The interface you see will depend on the particular driver and wireless card and may be different than the one shown in the illustration but you should look for something like "channel plan" or "country" or something similar. 
    In other Windows versions I suppose the procedure is similar in concept but I cannot provide the details as to how to do it.  
    
Linux 
    My laptop has an internal Intel-3945 wifi card and I have not been able to get it to work in the upper channels in Linux.  Again, it depends on the drivers and I do not know enough about Linux to mess about too much with drivers.  There's plenty of discussion about this problem in Linux to be found on the Internet but it is all quite esoteric and every adapter seems to be a different case.  On the other hand my RTL8187 external USB wireless adapter works fine in the upper channels with no tweaking needed.  I always carry an external adapter anyway because internal adapters are not very good when confronted with weak signals and an external adapter will perform many times better.

Here i found Kaspersky Internet Security 2010 Trial Reset trick. You don't need to download anything.

Just follow following steps and don't miss a single one.

Part 1: Create REG file

Copy following text into notepad and save it as KasperskyRestartTrial.reg somewhere..

Windows Registry Editor Version 5.00
[-HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SystemCertificates\SPC\Certificates]
[-HKEY_LOCAL_MACHINE\SOFTWARE\KasperskyLab\LicStorage]
[-HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\KasperskyLab\LicStorage]
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography\RNG]
"Seed"=hex:

Note that the icon of this file should look as reg file and not text file.



Part 2: Actual resetting
1. Disable Kaspersky Self-Defense. Open Kaspersky, go to Settings > Options> Disable the item "Enable Self-Defense"> OK



2. Run KasperskyRestartTrial.reg created in previous part.(Click "Yes" then "Ok")

3. Using right mouse button, click on Kaspersky icon near the clock and select Exit.

4. Go to Kaspersky data folder(C:\Documents and Settings\All Users\Application Data\Kaspersky Labs). To go direct, copy the address below. On Windows, click on Start button and run the address below.

%ALLUSERSPROFILE%\Application Data\Kaspersky Lab

5. Go to AVP9 folder and rename the Data folder to any other name. For example "DataMe" (Rename...dont delete!!!!)



6. Open Kaspersky Internet Security or Kaspersky AntiVirus.

7. If Kaspersky remakes the Data folder, then delete the new Data folder it recreated. For this you may have to exit kaspersky again as in step 3.
* Be careful not to delete the original folder from step number 5, because we need it!

8. Rename back the original Data folder to its original name. Start kaspersky again if you exited it in step 7.

9. Select "Enable test version (30 days)"

10. Enable Kaspersky Self-Defense!
DONE :)

Computer Laptop Battery Care and Usage Tips for getting more from a notebook battery.

1. Turn off Wi-Fi and BlueTooth - Most laptops have shortcut keys to instantly disable wireless networking.

2. Don't play computer games, music or DVD movies - Multimedia activities drain laptop batteries.

3. Disconnect all external device like PC Card modems, Firewire, USB devices and optical drives. Use the notebook touchpad instead of an external mouse.

4. Adjust your screen brightness - Dimming your display saves battery power.

5. Tweak Windows Power Options - Choose a Laptop power scheme that turns off the notebook monitor and hard disk after 10 minutes of inactivity.

6. Decrease or mute the Laptop Speaker Volume.

7. Turn off all scheduled tasks.

8. Turn off Auto-save features in Microsoft Office and other applications.

9. If your PC has a built-in wireless card, turn it off or disable it when not in use.

10. Programs that are run from a CD or DVD can be copied to and run from the hard drive, which typically consumes less power than an optical drive.

Looking for the longest battery life laptop ? Actually, many factors affect the amount of time that a laptop battery can deliver power before it must be recharged.

How to extend laptop battery life? Here are some more tips to improve your notebook's battery life:

1. If you do not use your laptop for extended periods of time (a week or more), remove the battery pack from the laptop.

2. Do not expose the battery to high heat or freezing temperatures. Do not leave your battery in your car in the summer. Hot batteries discharge very quickly, and cold ones can't create as much power.

3. Make sure to plug your laptop charger adapter into a UPS and not directly into a power outlet or surge protector.

4. If you have a nickel-metal hydride battery, completely drain and recharge the battery once a month to maximize its capacity to hold a charge.

5. Fully charge new battery packs before use. New pack needs to be fully charged and discharged (cycled) a few times before it can condition to full capacity.

6. For laptops that work as Desktop Replacement, the battery should be re-installed every 3-4 weeks and allowed to fully discharge.

7. Leaving a battery in a laptop while using an electrical outlet for long periods of time will keep the battery in a constant state of charging up and that will reduce the life cycle of the battery.

Battery-saving sleep modes: Should I use Stand By or Hibernate

Standby mode
Use standby to save power when you will be away from the computer for a short time while working - your monitor and hard disks turn off, all applications and open files are stored in RAM. When you want to use the computer again, it comes out of standby quickly, and your desktop is restored exactly as you left it.

Hibernation Mode
Use hibernation to save power when you will be away from the computer for an extended time while working - your computer shuts down to save power but first saves everything in memory on your hard disk. When you restart the computer, your desktop is restored exactly as you left it.

When you choose Start, Turn Off Computer in Windows XP, your options are Stand By, Turn Off, and Restart. To Hibernate, place the cursor over Stand By, then hold down Shift and click.
