|Does the black screen come back to a lit screen when inputs are touched (mouse, keyboard)?|
When the screen goes black is the laptop still powered on?
Things to look for:
- Could be a timed power setting for the display to go off (power save mode) in Windows Power options. It could be going into Standby Mode (Sleep) as well. Note there are differences in b/w "On Battery" & "On AC or plugged in" power saver settings too.
- Could be an LCD issue: Bad bulb (would stay dark though if it was a bad bulb), Bad LCD inverter, bad LCD cable connection(s).
- Could be a power interruption issue if the laptop is powering off of the battery or the AC.
- Or could be a more serious motherboard issue.
MOOOOooove! OH and you're welcome!
