Hi Satya,
Thanks for the reply. Actually i bought laptop with ubuntu 11.10 OS not with windows. And Processor is i5(3rd gen).
So 3 hrs of chargin and backup of 2 hrs is fine ??

TIA

Hi rajatkapoor,
6 cell battery charge under typical operating conditions should run up to 2.5 to 3 hours. However if the battery is used to run videos and high-end games it will drain faster.
Ensure the system has the latest BIOS version. To check the BIOS version, click Start and type 'msinfo32' in the search box. In the system information page, the BIOS version is listed with the release date.

For more information on battery usage and tips check this FAQ link:

Please revert if you have any clarifications.

Hi RajatKapoor,
I personally never got to work on Ubuntu but after little research I could find some threads that has few options to increase the battery performance. Have a look at these links:

Hope this helps and please revert for any clarifications.
