Laptop not working properly when on battery
My system is:
Dell Latitude C840 with NVidia GeForce4 440 Go graphics card. Redhat 9 with latest updates.
I have the 4363 driver installed and everything works fine when battery is charging. However, if I remove the power cable the system (mostly just X) will after a few minutes crash. The screen resolution will decrease and everything is streched horizontally. Colors also look odd.
My first guess is that it has something to do with power management, but it happens even if I keep on working on my laptop.
Has anyone experienced something familiar? If so did you find a solution? Any comments/surgestions will be appreciated.
