I have posted a few times on this laptop. It is a Core 2 Duo processor with an Nvidia G210m GPU running the latest 304 series binary driver and Ubuntu 12.04. I have gotten pretty much every issue with this laptop solved including suspend. However, the one thing I can't seem to straighten out is battery life. I bought a battery rated for a higher MWh and have tried every power saving trick I could find, but nothing seems to push the battery life beyond 2 hours and 20 mintues or so. I have tried both the nouveau driver and Nvidia binary. I have run both Ubuntu 12.04 and Fedora 17 on it and there is no variation. A full charge results in a little over 2 hours.

The tech specs say this is rated up to 4 hours under Windows. I know power management is a tricky thing, but has anyone had any success getting the battery life up on this model or something similar? Any help is much appreciated.
