Tips on Increasing Laptop Battery Life  

Posted by Laptop Tips

Battery life is one of the most important aspects people look at when buying laptop computers. The longer the battery lasts, the more work you can get done away from a power source. Therefore, it is important to take steps to reduce power consumption, and increase the overall life span of the battery.

1. Switch-off Wi-Fi and/or Bluetooth when you don't use it.

Wi-Fi and Bluetooth drain your battery power fast. When you are not connecting to a wireless network and any bluetooth device, try to switch off both to save your battery power.

2. Draw less power when using your laptop.

The more applications you run on your laptop, and the higher your power settings, the more the battery will drain during use. Running fewer programs at one time, and changing power settings, such as reducing the brightness of the display, will extend battery life. Running graphically intensive programs like games is especially hard on batteries, since graphics cards draw large amounts of power, and generate a lot of heat.

3. Do Away with unused peripherals.

Computer peripherals such as mice, external hard disk drives and external optical drives need electricity to run. When you are done using these equipments, unplug them from the system so they will no longer drain battery power. Laptops have a touchpad so you can actually work without a mouse.

4. Avoid extreme temperatures.

Laptop batteries are designed to function properly within a set range of temperature. Avoid using or charging your laptop in hot or cold conditions. Likewise, laptops normally run more efficiently when it is cooler. Try to keep the internal temperature down by keeping the fan free and clear for proper ventilation

You just got a shiny new laptop to use on your commute to the office, on business trips, vacations and at the coffee shop down the street. Congratulations! You'll be a productivity powerhouse! But hold your horses for a minute there, bucko.

Any road warrior will tell you life with a lappie isn't always easy. As a freelancer with a keyboard permanently propped up on my thighs (like right now on an airplane bound for Seattle), I've got a few hints and tips for extending the life of your laptop and easing the pain of the never-ending outlet and hotspot hunt.

Extend your battery life.

Laptop productivity on the cold, cruel and often electrical outletless road often depends entirely on how much juice you've got left. The screen draws the most power from your battery. When you don't have access to an outlet, dim your screen to the lowest setting to make your battery last as long as possible.

Also, disable unnecessary CPU-cycle-eating processes - like auto Bluetooth device and wifi network detection - to save juice and make your battery last longer.

Save your keyboard and screen.

At the beach house there is sand, at the coffee shop there are crumbs, and right now your fingers are covered in Dorito dust. Protect your keyboard from stray crumbage getting into the cracks with a protective cover. At a reader's recommendation, I invested in the iSkin which does double duty: it keeps crumbs out from between the keys and also protects the screen from keyboard scratches.

Another way to prevent screen scrapes is a piece of rubberized shelf liner cut to fit inside your lappie like the bologna in a sandwich when you shut it. I've also seen people use a thin piece of cloth.

If your laptop keys are already sticky and furry, give it a good cleaning with some compressed air, cotton swabs and elbow grease.

Keep it cool.

After an hour or so, a computer can burn one's thighs and wrists (like my super-heat conducting titanium Powerbook). If this is a problem for you, get material that doesn't conduct heat well between your skin and your lappie, like a lap desk or your laptop sleeve. Long-sleeved shirts with big cuffs help on wrists when the top of your keyboard gets hot to the touch.

Work offline.

Web-based email's great, but the dream of always-on Internet connectivity hasn't yet come true. Get yourself set up to work offline on your laptop on the plane and other wifi-less locations.

For example, Mozilla Thunderbird is a must-have install on your laptop. In addition to downloading all your mail locally for working with offline, Thunderbird 1.5 has excellent SMTP management so you can switch which server you send your mail through when you get online very quickly. Using a NetZero dialup account that requires you use smtp.netzero.net? Need to use the secure SMTP server at the office for work mail? No problem. You can set up multiple SMTP servers and associate them with different email accounts with Thunderbird.

For more on working offline or with a super-slow connection, check out previously-posted feature How to survive a slow internet connection.

Secure your data.

While you're out and about and on open wireless networks, make sure you've got a secure firewall installed on your laptop and that its settings are extremely restrictive. Turn off folder sharing and any local servers you have running (like a web, FTP or VNC) to keep others from peeking in on your data. Make sure your laptop's logins have strong passwords assigned.

Also, consider encrypting the data on your disk in case of theft, using a utility like Mac OS X's FileVault. If you're really concerned about someone grabbing your laptop and running, check out "Lojack for Laptops" software which helps you trace and recover your stolen computer.

Carry it well.

Your laptop spends a lot of time swinging over your shoulder, banging around on your back, bumping into the guy next to you on the subway, and sliding around on your car's back seat. Wrapping it up in that spare Linux tee-shirt and shoving it into your messenger bag full of gadgets probably isn't a good idea. Make sure that sucker's snug as a bug in a rug. Invest in a padded sleeve or bag made to carry laptops that'll protect it when your bag falls over or gets kicked. I really dig the spendy but stylish Booq bags and sleeves; a little research will turn up the right one for your budget and style.

Back up when you get home.

Portable computers deal with a lot more wear and tear than desktops, and this increases the risk of hard drive failure. So most importantly, make sure you back up the data on your laptop.

A few months ago, a panicked Lifehacker reader wrote in saying the laptop from which she runs her business was stolen and that she had no recent backup. DO NOT LET THIS HAPPEN TO YOU. Create a lappie docking station space at home where you can plug in to recharge the battery and hook up an external drive to backup your data. See more on how to automatically back up your Windows data here.

Pack some helpful extras.

If you've got a CD-R or DVD-R drive in your lappie, keep a few spare blanks or a USB drive for easy backup on the road. A 2 to 3 prong electrical plug adaptor might help in places where your 3 prong plug needs to go into a 2 prong outlet. And of course, an extra charged-up battery, an ethernet cable or phone cord or an extra mouse might be a helpful addition to your portable arsenal.

Notebook Processors  

Posted by Laptop Tips

Notebook Processors
In the following report we present all laptop processors which are available at the market at present and give a rough classification of the current consumption and the performance of the different architectures. An approximate rating with average benchmark values can be found in our beta version benchmark list of mobile processors (coming soon).
..
Intel Core 2 Duo (Merom)

This is the Core Duo and Core Solo successor with a longer pipeline and 5-20% more speed without more current consumption. As an addition to the Core Duo design there exists a fourth decoder, an amplified SSE-unit and an additional arithmetical logical unit (ALU).
Features are 2 cores, a 64-bit EM64T command amplification and 2 or 4 MB L2 Cache and 291 millions of transistors, which are finished in 65 nm. Furthermore all types support "Execute Disable Bit" technics, SSSE3 (SSE4), Enhanced Speedstep, LaGrande and most types the virtualisation technics (VT) Vanderpool.

The Core 2 Duo for laptops is identical to the desktop Cure 2 Duo processors but the notebook-processors work with lower tensions (0.95 to 1188 Volt) and a lower Frontside bus clock (1066 vs 667 MHz). The performance of equally clocked notebooks is 20-25% lower than Desktop PCs because of the lower Frontside bus clock and the slower hard disks.

The energy need of the processors is marked by pre-set letters in front of the type designation (number).E ... 55-75 WattsT ... 25-55 Watts (standard version in notebooks)L ... 15-25 Watts (low boltage)U ... <15> Intel product informations
..
Intel Core 2 Solo (Merom)
This is the successor of the Core Solo and technically a Core 2 Duo with only one core. It will be available for laptops starting with the 3. quarter 2007 and only as an Ultra Low Voltage (ULV). Therefore the core tension is very low (=economic). 2 versions are planned at moment:
U2100, 1.2 GHz, 1MB L2 Cache, 533 MHz FSB, 5 W max. TDP
U2200, 1.06 GHz, 1MB L2 Cache, 533 FSB, 5 W max. TDP
Intel Core Duo (Yonah)

Pentium M successorDouble Core processor with a very good relation of performance to current consumption. The 2 MB L2 Cache are used together by the double. The maximum capacity of 31 watts is only 4 watts more than with the Pentium M (predecessor). Both cores are lowered automatically and independently of each other by speed steps down to 1 GHz. In addition it now supports also SSE3 instructions.
..
After first benchmarks the Core Duo completes all tests at least just as fast as a equivalent Pentium M. With applications, which were designed for multi-processors, the performance can be nearly twice as fast as with the Pentium M (e.g. CineBench around 86% fast)
Models (clock, TDP):T2700 (2.33 GHz, 31 W, FSB 667 MHz)T2600 (2.16 GHz, 31 W, FSB 667 MHz)T2500 (2.00 GHz, 31 W, FSB 667 MHz)T2450 (2.00 GHz, FSB 533 MHz)T2400 (1.83 GHz, 31 W, FSB, 667 MHz)T2350 (1.86 GHz, FSB 533 MHz)T2300 (1.66 GHz, 31 W, 667 MHz)T2250 (1.73 GHz, FSB 533, MHz)T2050 (1.60 GHz, FSB 533 MHz)T2050E (1.60 GHz, FSB 533 MHz): current saving version with 1.3 instead of 1.4 Volt supply voltageL2500 LV, 1.83 GHz, FSB 667 MHzL2400 LV, 1.66 GHz, 15 W, FSB 667 MHzL2300 LV, 1.50 GHz, 15 W, FSB 667 MHzU2500 ULV, 1.20 GHz, 9.5 W, FSB 533 MHzU2400 ULV, 1.06 GHz, 9.5 W, FSB 533 MHz
Pentium Dual Core T2060: 1.6 GHz, FSB 533 MHz, 1 MB L2 Cache (the return of the name Pentium, though Yonah core)Pentium Dual Core T2080: 1.73 GHz, FSB 533 MHz, 1 MB L2 Cache

Core Duo produkt description

Intel Core Solo
Single core version of the Core Duo and successor of the Intel Pentium M; Because of the 65nm reduced structure width also smaller current consumption than Pentium M (maximally 27 Watts); the performance is comparable with the equivalent clocked Pentium M (somewhat faster because of a few improvements).
Models:T1200 mit 1.50 GHz, FSB 667 MHz, 2MB L2 CacheT1300 with 1,66 GHz 2MB L2 CacheT1350 with 1.86 GHz, FSB 533 MHz, 2MB L2 Cache (about the same level like Pentium M 750)T1400 mit 1.83 GHz, FSB 667 MHz, 2MB L2 Cache
Ultra low voltage models (maximum 5.5 Watt):U1300 mit 1.06 GHz, FSB 667 MHz, 2MB L2 CacheU1400 mit 1.20 GHz, FSB 667 MHz, 2MB L2 CacheU1500 mit 1.33 GHz, FSB 667 MHz, 2MB L2 Cache

Core Solo product description

Pentium M
Intel Pentium M
900 - 2260 MHz, 1-2 MB level 2 Cache, 90nm and 130nm production process, 400 and 533 MHz front Side bus (FSB);With Intel chip set (855 or 915) and Intel WLAN also available with the name Centrino (name for the package).In the comparison very fast per megahertz and very modest with weaknesses in floating point operations.It is also available as a low voltage version with very small current consumption.

Celeron M
Intel Celeron M
800 - 1500 MHz, 512KB - 1 MB level 2 Cache. It is a Pentium M with halved level 2 Cache and limited on FSB 400. The characteristic of this processor is the speed, which is hardly slower than an equivalent Pentium M. However it can change the speed not dynamically like the Pentium M and therefore needs without load more current.It is also available as Low Voltage Version with very small current consumption.
The 4xx series is based upon the Core Solo and has a Front Side Bus (FSB) of 533 MHz, but only 1 instead of 2 MB L2 Cache. It seems to be bring enough performance for office applications (as the 3xx series).
The 5xx series is based upon the Core 2 Solo (Merom architecure) and is slightly faster than an equally fast 4xx Celeron M. The Celeron does not support any virtualisation technics and has no ViiV and vPRO certificate (in contrary to Core 2 Solo).
410: 1.46 GHz, FSB 533, 1MB L2 Cache420: 1.60 GHz, FSB 533, 1MB L2 Cache423: 1.06 GHz, FSB 533, 1MB L2 Cache, Ultra Low Voltage = current saving
520: 1.60 GHz, FSB 533, 1 MB L2 Cache, 64 Bit530: 1.73 GHz, FSB 533, 1 MB L2 Cache, 64 Bit
523: 0.933 GHz, FSB 533, 1MB L2 Cache, 5 Watt max TDP, Ultra Low Voltage = current saving (starting with quarter 3 2007)

Intel Mobile Pentium 4 M
2,4 - 3.46 Ghz (in former times starting from 1,4 Ghz) with FSB 533 (in former times 400) and 512KB to 1 MB level 2 Cache. It is produced in 90 - 130 nm production process and is relative slow, but uses much current and heats up considerably per megahertz (compared with mobile processors like Pentium M). Technically it is a Pentium 4 with some current saving mechanisms (e.g. speedstep) and less current consumption.
There existed type variants of Mobile Intel Pentium 4 for DTR (desktop replacement laptops). It supports Enhanced Speed Step and other features for the reduction of current consumption, but needs clearly more current than the Pentium 4-M models. It was intruduced with FSB533-connection and clock frequencies between 2.4 and 3.06 GHz.

Intel mobile Celeron 4 M
Technically it is a Pentium 4 M however without speed steps and with less level 2 Cache. In contrast to the Celeron M it is very slow, since the long pipeline of architecture needs a large level 2 Cache. Slow, warm and very hungry for current per megahertz.

AMD Turion64 X2
64 bit dual core (2 core) processor, code name Taylor (2 x 256 KB L2) and Trinidad (2 x 512 KB L2), DDR2-667 support, Pacifica (AMD-v) virtualisation technics, 31-35 W TDP, socket S1, 90 nm fabrication, separated L2 Caches, integrated 333 MHz DDR, 800 MHz Hypertransport
AMD Turion 64 X2 is intended to be positioned against the Intel Core Duo was presented in 17. May 2006. The current consumption is not higher than with Centrino-Duo-notebooks (TL-45 with ATI Xpress and Mobility Radeon X300). This means, that approximative the same battery runtime and fan functions can be expected (with this chipset). However, the performance was 20% below the T2300 (1.66 GHz) due to the lower L2 Cache (Core Duo has 2048 Kbyte shared L2 Cache). Nevertheless, the performance is sufficient.
In March 2007 a Turion 64 with reduced structure was announced (as a response to Intels Santa Rosa Core 2 Duo), which have up to 2.3 GHz.

RAM Failures  

Posted by Laptop Tips

Bad RAM is somehow harder to diagnose as similar symptoms may be caused by software problems, other hardware problems or even motherboard failure. However if you experience any of these symptoms, you should check for bad RAM before attempting any other troubleshooting.

Symptoms:

  • Windows doesn’t start showing different error messages each time.
  • Windows crashes (blue screen) or freezes frequently.
  • Windows crashes as soon as you try to start a program.
  • Unexplained random crashes and freezes without error messages.

Troubleshooting:

Download Memtest86+ and burn it to a CD or make a floppy. For CD get the “Pre-Compiled Bootable ISO (.zip)” and for floppy (if you can start your laptop from a floppy drive) get the “Pre-Compiled package for Floppy (DOS – Win)”. If you are making a CD, you will have to “burn” the ISO image to the CD, not just copy it. There are numerous guides how to do that with different CD burning software (you cannot do it with the build-in Windows CD burning). In general you need to find where on the menus of your favourite CD burning program it says something like “Create CD from Image” or “Burn Image to Disk” or similar. Then select the .iso image file and burn it. If your laptop crashes a lot and you cannot make the Memtest CD or floppy, ask a friend or talk to your local repair shop and ask them to make one for you (it probably will be $5-$10).

Start the laptop from the CD/floppy and let Memtest86 run for a couple of hours. To start your laptop from the CD you may need to select a temporary boot device by pressing F12, F11 or F8 as soon as the logo appears on the screen (2-3 sec. after turning it on) or immediately after entering the BIOS/HD password if you have set one. If that doesn’t work, you will have to change the boot order in the BIOS. To do that try pressing F1, F2 or “Esc” (for Toshiba) to get to the BIOS settings and make the CD the first booting device.

If Memtest86 finds errors (there usually will be thousands of them) try removing one of the RAM chips (if your laptop has two of them) and run Memtest86 again.

Most laptops have two RAM slots that are easily accessible under a tab on the bottom. Others have just one slot there and the other is under the keyboard, on some there is RAM soldered on the motherboard (Toshiba), and a few laptops have just one RAM slot.

Removing laptop RAM: remove the screws, touch an exposed metal part of the laptop with both your hands (usually the VGA connector has two visible screws that you can touch to discharge any static electricity), then release both clips that hold the RAM and it will pop up. Hold the RAM on the sides (avoid touching the chips) and gently pull it out. To install, insert back the RAM and gently push it down until it locks in place.On some laptops the RAM is under the keyboard, or one chip is on the bottom of the laptop as described above, and another is under the keyboard. It is usually very easy to remove the keyboard on almost all laptops. Try to find the service manual for your model and find the description there. Alternatively, there are step-by-step picture guides on the Internet for most laptop models.

Memtest86 will run until you stop it by pressing “Esc” key. If your laptop freezes or restarts by itself while running the RAM test, it either is overheating or has another hardware problem.

Save battery usage on your laptop  

Posted by Laptop Tips

Here are some tips to help you save the batteries on your laptop:

What consumes power?
Electronic and mechanical components consume energy (Electricity).
There are devices like the hardisk, DVD reader, screen etc. There is also the Motherboard and the processor.
So you should keep in mind, the more you use the processor i.e. the Cpu rate used will consume more power.
When you are playing to 3-D games, more power is consumed than using a simple text editor.

How to reduce consumption of power
-The Screen brightness can be adjusted. Try to reduce but enough to be able to see easily.
-Adjust the Energy Usage in Windows so that it can turn your screen and hardisk to stand by mode when not in use.
- You can even stop Windows, Use the hibernation Mode. This will help Windows to start more rapidly.
- There’s an option to avoid the CPU to run at a maximum speed, which will help to reduce power usage.
- Some devices (graphic cards, modems, PCMCIA cards) do turn off when they are not used. So some devices cannot be used when they are on power saving mode.
- Use integrated devices on your laptop and avoid using the mouse (it consumes more power). So try to reduce the use of USB devices.
- Defragment your hardrive regularly, i.e. once each month. Less the hard disk is fragmented, the less there will be trips heads playback, and therefore there will be less current consumption. Use BootVis which is useful to manage your system files at startup.. then windows will start more rapidly.
Another important fact: The more you have programs running and consuming CPU time, the more you eat of course.
- Close down on programs running in the background. Itunes, Desktop Search, etc. All these add to the CPU load and cut down battery life. Shut down everything that isn’t crucial when you’re on battery.
- Add more RAM - This will allow you to use the laptop memory, rather than relying on virtual memory. Virtual memory results in hard drive use, and is much less power efficient. Note that adding more RAM will consume more energy, so this is most applicable if you do need to run memory intensive programs which actually require heavy usage of virtual memory.
- Keep operating temperature down - Your laptop operates more efficiently when it’s cooler. Clean out your air vents with a cloth or keyboard cleaner.

Configuration of your OS
It is important to disable unnecessary programs and services.

Disable unnecessary services, especially the Indexing Service. This service is a little heavy on CPU and lots of disk access.

Reduce the number of programs launched at startup. There are certainly full are useless (QuickTime Task Java Update Scheduler, Office toolbar, "Quick Start" Office, RealPlayer, etc.).

Change the subject of Windows: Use the standard theme. Indeed, the Aqua theme for Windows requires a bit more computing power, and therefore consumes a little more current.

Disable visual effects (animations, transition effects). They are pretty, but require the CPU to make further calculations, and thus consume more current. Especially under Vista, and Linux (with Beryl / Compiz / XGL): All the 3D effects and transparency are major consumers of CPU. Turn them off.

Disable ClearType.
If it is not necessary, cut the sound (mute);

Avoid animated screensavers (3D or otherwise). Choose the screen saver or the standard Windows screen blank. Do not forget to enable the economy to energy to the screen in "Power Management".
If you do not use your WiFi connection, disable it. This saves your WiFi to deliver consistently to find an access point (it consumes power).

Under Windows 95, 98 and ME, use programs such as ATM (Another Task Manager) to force the processor to execute the instruction HTL (halt) when it does nothing. This helps to save energy. (Some laptops are already supplied with utilities doing this). This manipulation is not necessary under Windows NT, 2000, XP, 2003 and Linux because they already use a standard instruction HLT.

Maintaining the battery  

Posted by Laptop Tips


Intro
Li-Ion batteries, are the mostly used technology nowadays.This type of battery cam be found on most laptops and netbooks as their main advantage is their ability to pack up a large amount of energy in a small volume. These batteries come along with many other advantages that in a way justify their cost prohibitive cost. Some of them are listed below: * Secure compared to the first versions of lithium batteries (covered with plastric) * Self-discharge (when not in use it will naturally be discharged) * Require less maintanance. * The physical properties of lithium ensures a good energy/ volume ratio. These advantages come along with several drawbacks: * Slow to charge up. * Very expensive. * Low resistance to high temperature * Batteries wear out over time. * Deterioration occurs when the battery discharge below 10%


How to make a good use of your battery
Changing your battery will cost a lot of money....So if you have one that is still in good state and working properly or if it is imperative for you to buy a new one ,here are some tips, on how increasing its lifespan and make an optimal use. Before getting started, here's are some technical terms, you better get used to before going any further. The battery voltage measured in Volts (V) As for the amount of electricity, it is measured in Ampere/hours (Ah) or milliamp-hours (mAh) The efficiency of a battery can be determined through this equation: Voltage (V) x amount of electricity (Ah) = Energy (Wh)


Points to consider
* Never exceed the discharge current specified by the manufacturer. * Don't to use your battery to power other machines. * Perform Calibration, minimum 2 times a month: this process is to "reframe" your battery. Perform it a maximum discharge level (not below 10%) , it must then be fully recharged without interruption (OS in standby mode). * When you buy a battery, the first thing to check is (after its power in W) , the date of manufacture (don't forget that your battery deteriorates with time)... * You should never buy cheap batteries, such as the ones imported directly from China, they are quite unsafe. * Don't fall below 10% of charge. Normally your OS, directly put the computer to sleep mode when only 15% remain in charge. You can really lose 20% of the efficiency of your battery. * Take care battery charger: its not just a simple power cord , you will spare some battery use while using it(on one end it charge up your battery and on the other it power up your laptop.


Things to avoid
*Unplug the power cord of a laptop when it is off, to avoid micro-charge of the battery. *Never try repairing a battery by opening it. You can get injured (burned) or seriously become intoxicated. *Rechargeable batteries, lead acid batteries & lithium are harmful to health and to the environment So they should never be thrown away. They must be completely recycled.

Upgradig your laptop  

Posted by Laptop Tips



It's not really easy to upgrade components on a laptop. 

Upgrading a laptop is divided into 2 categories:1. The change of internal components

- Memory (the simplest operation). 
- The Hard disk. 
- The optical drive. 

Upgrading the motherboard, processor or the screen, is very expensive and complex ...2. The addition of PCMCIA cards:

- USB 2.0 and Firewire. 
- Network card. 
- WIFI map. 

In addition the possibility for USB or Firewire: 

- USB Hub. 
- Keypad. 
- Reader / writer optical (CD / DVD). 
- Floppy Drive, memory cards. 

Every peripherals that plugs into these ports ... 


Adding memory in a laptop. 

This operation is the easiest to achieve, we must know where to find the location of them: sometimes with a trapdoor on the underside of the laptop, sometimes under the keyboard ... The manual of the laptop will often be necessary to locate them. 

This fact must then determine the type of memory to use (PC100 or PC133 for older PC2100, 2700 or 3200 for new laptops, all in SODIMM format 

Changing the hard disk of a laptop. 

This operation is somewhat more complex: it will be necessary, as in the case of memory modules, locate the door concealing the hard disk. 

This is generally set on a rack: it will need to unscrew and then recover the adapter pin fixed on the front of the disk, reinstall it exactly the new disk, and finally reinstall the operating system. 

Unlike a desktop PC, mobile ones generally offer the possibility of installing a single hard drive. 
These hard drives are formatted in 2.5 "(against 3.5" for desktops). 
The interface is most often PATA (or UDMA). 

Upgrade the optical drive. 

To replace a CD drive or combo DVD / CD with a DVD burner, it will often have to go through the manufacturer of the computer to hope to find a compatible hardware. 
Indeed, if the optical drives of desktops are usually provided in standard format 5.25 "is different for each laptops, the racks are often different from one manufacturer to another. 

It is sometimes not possible to change the drive, which is incorporated directly into the casing of the laptop. 
The only solution in this case would be to buy an external USB or Firewire Drive. 

Sound  

Posted by Laptop Tips

If you are a computer user, whether a moderate or a frequent user, it is evident that you use some sound system with your PC and as such it is often seen that there is some problems with the sound that you must deal with. Some of the common sound problems encountered by PC users include when sound can be heard coming out of only one speaker or when you need help because the volume control of your speaker is not functioning. 

For the first problem, it is imperative you pinpoint exactly what is causing the problem – whether the sound card or the speaker cable or the speakers themselves. To tackle with the first type of problem, check if the cables that connect your sound card to the speakers are firmly in place and ensure that the sound balance setting of your speakers is neither to extreme right nor to extreme left but in the middle position. If you are still having sound problems then to find out if your speakers are faulty and need repairing, connect them with a separate sound source and check the quality of sound output. Now what can you do if you cannot control the volume of your speakers? 

The basic reason why this happens is that either you have forgotten to insert batteries or you have overlooked connecting the speakers to an external source of power. Taking care of these mistakes can fix the sound problem of your PC. However if your sound problem is centered on why you cannot see the red light on your speakers after you have turned them on, then be assured that it is only a power issue taking care of which your problem also gets solved.

Airport Security Checks
Airport security has been tightened dramatically as a result of the terrorist attacks in the United States on September 11, 2001. This has obvious ramifications for travelers. Get to the airport two or three hours earlier than normal. You can expect security clearance to take an unprecedented amount of time.Take nothing with you on your person or in carryon bags that has sharp edges or could be construed to be a weapon. This includes pocketknives, corkscrews, dinner and carving knives, forks, screwdrivers, pointed pliers, letter openers, scissors and similar items. After highjackers used box cutters as weapons, the FAA has issued guidelines that will be interpreted strictly by airport security workers. All suspect items will be confiscated so if they are necessary to your trip either pack them in luggage that is being checked or send them to your destination in advance.

Plan ahead. Pack your laptop with security and boarding gate checks in mind. Use an easily accessible inner or outer compartment of one of your carry-ons so that your laptop can be easily removed and restowed at the security checkpoint. Also make sure to use a carry-on that won't be deemed too big at the boarding gate - or be prepared to quickly remove your laptop and stow it in a smaller case if it is.

In preparation for airport security checks, use the "suspend" mode (Windows) as an alternative to making sure your battery has enough power to boot up. Activate the suspend mode the last time you use your laptop before going to the airport. It will restart quickly and consume almost no battery power, leaving the maximum battery charge if you want to work during the flight. (for Mac users, it is the "sleep" mode)When you go through airport security, you may be asked to turn your laptop on. Make sure your battery has enough power left to avoid delays. The process may also be sped up by booting from a floppy diskette.X-ray machines at airports are not a threat to your laptop's hard-drive or floppy disks. However, the security checkpoint conveyer belt is a target for thieves who watch for unattended equipment passing through the x-ray machines. As a result you may want to have a security guard hand check your machine rather than putting it through the conveyer.

Hotel Room Security
If you're feeling insecure about leaving your notebook computer in the hotel room. leave it stowed in your room but take the removable disk drive with your when you leave.

Disguise Your Laptop
To help safeguard against theft, disguise your computer while traveling. Trade in the traditional computer case for a less conspicuous bag such as a Crumpler Case.

5 Tips for Using a Laptop Computer  

Posted by Laptop Tips

  • Un-ergonomic Laptops - the design of laptops violates a basic ergonomic requirement for a computer, namely that the keyboard and screen are separated. In the early days of personal computing desktop devices integrated the screen and keyboard into a single unit, and this resulted in widespread complaints of musculoskeletal discomfort. By the late 1970's a number of ergonomics design guidelines were written and all called for the separation of screen and keyboard. The reason is simple - with a fixed design, if the keyboard is in an optimal position for the user, the screen isn't and if the screen is optimal the keyboard isn't. Consequently, laptops are excluded from current ergonomic design requirements because none of the designs satisfy this basic need. This means that you need to pay special attention to how you use your laptop because it can cause you problems.

  • Laptop User Type - how to you use your laptop? Are you an occasional user who works on your laptop for short periods of time or are you a full-time user with the laptop as your main computer? Occasional users will have less risk of problems than full-time users. All users should pay some attention to how they use their laptop, but full-time users may have more problems.


  • Laptop Posture - as indicated above, laptops violate basic ergonomic design requirements, so using a laptop is a tradeoff between poor neck/head posture and poor hand/wrist posture.
    • Occasional Users - because the neck/head position is determined by the actions of large muscles, you are better off sacrificing neck posture rather than wrist posture. For occasional use:
      • find a chair that is comfortable and that you can sit back in
      • positioning your laptop in your lap for the most neutral wrist posture that you can achieve
      • angling the laptop screen so that you can see this with the least amount of neck deviation
    • Full-time Users - if you use your laptop at work as your main computer you should:
      • position this on your desk/worksurface in front of you so that you can see the screen without bending your neck. This may require that you elevate the laptop off the desk surface using a stable support surface, such as a computer monitor pedestal.
      • use a separate keyboard and mouse. You should be able to connect a keyboard and mouse directly to the back of the laptop or to a docking station
      • use the keyboard on a negative-tilt keyboard tray to ensure a wrist neutral posture
      • use the mouse on an adjustable position mouse platform
      • follow the postural guidelines for working at a computer workstation
  • Laptop dimensions - many laptops offer large screens (15" plus) and can work as desktop replacements (giving the viewing area of a 17" monitor). However, think about where you will most use your laptop to help you choose the best size. The larger the screen the more difficult it will be to use this in mobile locations (e.g. airplane, car, train). There are a number of smaller notebook and ultraportable laptops on the market. Consider issues of screen size and screen resolution. A small screen (e.g.12.1") will be useful in mobile settings, but if the resolution is high (e.g. XGA - 1024 x 768) make sure that you can read the screen characters and can easily use the input device to point to areas on the screen. The smaller the laptop, the smaller the keyboard, so make sure that you can comfortably type on a keyboard that may be only 75% the size of a regular keyboard.


  • Laptop weight - if you are a mobile professional who will be frequently transporting your laptop think about the weight of the system. By the word 'system' I mean the weight of the laptop plus the required accessories (e.g. power supply, spare battery, external disk drive, zip drive, CD_RW etc.). Many lightweight portables can become as heavy as regular laptops when you add the weight of all of the components together. If your laptop + components weighs 10lbs or more then you should certainly consider using a carry-on bag that you can pull along. If you want a smaller bag and can comfortably carry your laptop consider a good shoulder bag design

    Posted by Laptop Tips

    You just got a shiny new laptop to use on your commute to the office, on business trips, vacations and at the coffee shop down the street. Congratulations! You'll be a productivity powerhouse! But hold your horses for a minute there, bucko.

    Any road warrior will tell you life with a lappie isn't always easy. As a freelancer with a keyboard permanently propped up on my thighs (like right now on an airplane bound for Seattle), I've got a few hints and tips for extending the life of your laptop and easing the pain of the never-ending outlet and hotspot hunt.

    Extend your battery life.
    Laptop productivity on the cold, cruel and often electrical outletless road often depends entirely on how much juice you've got left. The screen draws the most power from your battery. When you don't have access to an outlet, dim your screen to the lowest setting to make your battery last as long as possible.

    Also, disable unnecessary CPU-cycle-eating processes - like auto Bluetooth device and wifi network detection - to save juice and make your battery last longer.

    Save your keyboard and screen.
    At the beach house there is sand, at the coffee shop there are crumbs, and right now your fingers are covered in Dorito dust. Protect your keyboard from stray crumbage getting into the cracks with a protective cover. At a reader's recommendation, I invested in the iSkin which does double duty: it keeps crumbs out from between the keys and also protects the screen from keyboard scratches.

    Another way to prevent screen scrapes is a piece of rubberized shelf liner cut to fit inside your lappie like the bologna in a sandwich when you shut it. I've also seen people use a thin piece of cloth.

    If your laptop keys are already sticky and furry, give it a good cleaning with some compressed air, cotton swabs and elbow grease.

    Keep it cool.
    After an hour or so, a computer can burn one's thighs and wrists (like my super-heat conducting titanium Powerbook). If this is a problem for you, get material that doesn't conduct heat well between your skin and your lappie, like a lap desk or your laptop sleeve. Long-sleeved shirts with big cuffs help on wrists when the top of your keyboard gets hot to the touch.

    Work offline.
    Web-based email's great, but the dream of always-on Internet connectivity hasn't yet come true. Get yourself set up to work offline on your laptop on the plane and other wifi-less locations.

    For example, Mozilla Thunderbird is a must-have install on your laptop. In addition to downloading all your mail locally for working with offline, Thunderbird 1.5 has excellent SMTP management so you can switch which server you send your mail through when you get online very quickly. Using a NetZero dialup account that requires you use smtp.netzero.net? Need to use the secure SMTP server at the office for work mail? No problem. You can set up multiple SMTP servers and associate them with different email accounts with Thunderbird.

    For more on working offline or with a super-slow connection, check out previously-posted feature How to survive a slow internet connection.

    Secure your data.
    While you're out and about and on open wireless networks, make sure you've got a secure firewall installed on your laptop and that its settings are extremely restrictive. Turn off folder sharing and any local servers you have running (like a web, FTP or VNC) to keep others from peeking in on your data. Make sure your laptop's logins have strong passwords assigned.

    Also, consider encrypting the data on your disk in case of theft, using a utility like Mac OS X's FileVault. If you're really concerned about someone grabbing your laptop and running, check out "Lojack for Laptops" software which helps you trace and recover your stolen computer.

    Carry it well.
    Your laptop spends a lot of time swinging over your shoulder, banging around on your back, bumping into the guy next to you on the subway, and sliding around on your car's back seat. Wrapping it up in that spare Linux tee-shirt and shoving it into your messenger bag full of gadgets probably isn't a good idea. Make sure that sucker's snug as a bug in a rug. Invest in a padded sleeve or bag made to carry laptops that'll protect it when your bag falls over or gets kicked. I really dig the spendy but stylish Booq bags and sleeves; a little research will turn up the right one for your budget and style.

    Back up when you get home.
    Portable computers deal with a lot more wear and tear than desktops, and this increases the risk of hard drive failure. So most importantly, make sure you back up the data on your laptop.

    A few months ago, a panicked Lifehacker reader wrote in saying the laptop from which she runs her business was stolen and that she had no recent backup. DO NOT LET THIS HAPPEN TO YOU. Create a lappie docking station space at home where you can plug in to recharge the battery and hook up an external drive to backup your data. See more on how to automatically back up your Windows data here.

    Pack some helpful extras.
    If you've got a CD-R or DVD-R drive in your lappie, keep a few spare blanks or a USB drive for easy backup on the road. A 2 to 3 prong electrical plug adaptor might help in places where your 3 prong plug needs to go into a 2 prong outlet. And of course, an extra charged-up battery, an ethernet cable or phone cord or an extra mouse might be a helpful addition to your portable arsenal.

    Next up: how to find a wifi hotspot when you're out and about with your laptop.

    SEO marketing  

    Posted by Laptop Tips

    SEO Marketing and effective Search Engine Optimisation are all about improving your website’s organic (natural, non sponsored) rankings in the SERPs (Search Engine Result Pages) for relevant keyword phrases, which convert to targeted traffic, conversions and revenues.

    Most Internet users believe that websites found on the first page of the organic SERPs are the marketing leaders in their particular field. High ranking gives those sites authority because in the searcher’s eyes the engines have endorsed them for those particular keywords.

    Sites listed on the right side of the page, or sometimes at the top of the page in a colour-coded area, are seen as “ads” (which they are) and appear because an advertiser paid for them to be there.

    An valuable internet marketing campaign can also make use of either natural search engine optimization or paid SEO such as Pay Per Click services. Where some online companies are concerned, a proper blend of non-paid and paid options have streamlined search engine marketing service and yielded the best outcomes.

    Affiliate internet marketing is an excellent way for an online product or site to reach out a wider audience or market. If you possess an existing online item and intend to promote is a far-reaching as you can, you can use an affiliate to promote the merchandise for you. This internet branding strategy can help your business boost online profits within a targeted time frame.
