Hi! I have a old acer 1200 with xp home on it just as a computer for a young kid to play with. recently it started shutting down unexpectedly. or so it seemed. It actually seems to be going into standby mode, but when i hit the mouse or a key the screen backlight does not return. in the right light you can see the screen and manipulate it, but the backlight will not come back until you restart.

I have tried updating the video and display adapter drivers with no luck. there are no errors being recorded in event viewer either. Anyone had this problem?? any help will be appreciated.. Thanks.

You removed the old video drivers...and then installed new/fresh drivers?

Installing drivers on top of troubled drivers...can lead to frustration.

Just the video drivers...they seem to sometimes cause problems with hibernation/standby.
