Hello,

When I start my laptop up running on battery I can't adjust the screen brightness so it is stuck at 0% brightness. The weird thing is is that when I start the laptop up when its plugged in the brightness can be adjusted and its fine, I can even take it off charged and I can still adjust. Its just when I start up on battery its stuck at 0% and when I plug it in you can't change it.

Any ideas?

Thanks in advance

it might be just on power saver mode, allot of laptops pre set the brightness while on it

Thanks, but I've already checked this, all settings are high perfomance with supposedly max screen brightness.
