How old is it, and when did this start happening ?

Any recent updates done ?

Do you have any Restore Points ?

Dark, or just darker ? When does this happen ?


Check your power settings ? Some laptop manufacturers have built-in darken facility when batter reaches certain level ?

Is the battery removable ? If so, try it without the battery just with direct power connection ... does it still happen ?


Laptop brand/make/model?

Lots of possibilities, in so many settings before need to consider hardware faults.

Bit of a shot in the dark but you might mean that the display dims but does not go blank after, say, 30 seconds of inactivity and returns to its normal brightness if you start using the keyboard or mouse once more.

See these methods of controlling this behaviour
Add or Remove Dim display after from Power Options - TenForumsTutorials
Add or Remove Dimmed display brightness from Power Options - TenForumsTutorials
or you can change the dimming behaviour directly using PowerCfg commands, see

Writing using correct grammar and stating what laptop you have might help get a useful reply

Probably just 'screen off' or 'monitor off'. Mine does that. You can set the timeout.


also here:

I notice that the OP has been re-written.

So the display is turning off not just dimming.

I cannot see any explanation of when this happens.
