Comment 2 for bug 776637

Happens on my N130 as well. Few points not mentioned by the reporter:

- It only happens on battery mode IF the screen brightness is set to anything brighter than the MINIMAL BRIGHTNESS. Then the screen starts to flicker between the minimal and the set brightness.
- If it starts flickering there is not much you can do (apart of ctrl+alt+delete). Fn + Brightness Up/Down doesn't work.
I found that it is possible to stop flickering by pressing Fn+volume up/down as soon as the flickering starts.

Hope this helps!
