My laptop works perfectly when it's plugged in but when I am on battery, it will turn off randomly. Usually after 2 or 3 hours but not always. It will occasionally not turn off but freeze completely. In that case the screen has half of the pixel green or pink and there's a bit of flickering. When I turn the laptop on, it boots normally but it may turn off randomly again after a while.
I am wondering if disabling the power saving mode on some of the laptop components could help me figure out what's wrong.
Which component with a power saving mode should I try to disable?
- XPS 13 Ivybridge 8Gb RAM, 256 SSD, Ubuntu 14.10
- I got this laptop 1.5 years ago. The battery lasts around 5h.
