CentOS on old Sony laptop (battery issue)

Post by sndlt » 2015/03/20 00:44:56

I installed CentOS 7 on a laptop that used to run Windows Vista and 7.

But when I leave it on for a while come back, it's always hibernated with a battery level of 0 or barely above.

Somehow it seems like power supply gets cut off when CentOS gets into screensaver or sleep mode. This never happened in Windows.

Does CentOS have any detailed screensaver or power settings that I can modify to make it stay up all the time?

It's so weird when power supply is connected the whole time.
