How withstand your laptop away from your sockets?

For more time work or entertainment outlet from your Laptop: 
1. Create non-energy-Hardware Profiles (right-click on My Computer and select Preferences), disabling wireless, Ethernet, VGA, PCMCIA, and USB ports. 
2. Reduce the brightness of the screen to a minimum and turn off when not using it (in Control Panel -> Windows Power Options give the time to close the screen). 
3. Do not use the CD / DVD. 
Good luck.
