Hey,

I’m planning to get a Lenovo T420 with the Nvidia Optimus NVS4200 with a 9-cell battery. I had a question regarding battery life. On Ubuntu 12.04, how much battery life are u guys getting? Is it comparable to that in windows? (~10 hours) Also, would it be possible to follow all this method in CentOS 6.2 (since I prefer something very stable and not requiring regular updates).

Thanks for your reply.

Munaf.
