Am running opensuse 11.2 along with windows vista on my thinkpad t400 - which has the ‘switchable graphics’ capability. The switchable graphics does not work on linux, but I am seeing large differences in the battery life too.
I get about 2 hrs of running time on my 9-cell battery when I am running Linux, whereas with the ‘performance’ mode in windows vista, I get almost 4 hrs (3 hrs 48 mins). Switching to the energy saving mode in vista gives me just over 5:30 hrs running time.
Any suggestions on how I can change things around to get more life on opensuse?
Thanks in advance.
