Solved Unable to adjust or change brightness

[KokoKid]

Describe the problem

Brightness will not go up when I tell it to. Screen too black. Unable to adjust brightness from control panel

What have you tried?

Restart (twice) Disabled display drivers, and Monitor drivers and re-enabled

Help? P.S. sorry for making so many threads ;(

Hi @KokoKid.
It sounds like it could be a problem with a driver update. Did you perform a Windows update recently?
I did a search I found this: Solved Laptop screen brightness won't adjust

I hope this can help.

Try this:

RUNNH

100- Go into Safe Mode and see if the problem exists.

120- If the problem is the same the issue is probably with your hardware, Go To End;

130- If the screen brightness is fine Go To 140

140- boot into Windows, go to Device Manager, Click Monitor and uninstall whatever shows up there, then reboot.

150- If on reboot things work, Go To End;

160- If things are the same go to 170

170- Cruelsister should stick with software.

End

Driver automatically updated itself. That's weird. Roll backed and should be good for now.

Above were the (2) steps that made me *Lol*!

I'll hope all stays 'good'.
If 'optional updates' remove system functionality, you can deactivate them to no longer be automatically by...

1- Under settings...

1.1- Choose "Control Panel"

1.2- From "System and Security" find...

1.3- Windows Update >> "Turn automatic updating on or off"

1.4- Like Cats-4_Owners-2, you may opt to automatically download & install only "Important updates"

1.5 Unlike Cats-... , you might not wish to completely ignore 86 optional updates which are available
(or maybe you do)
