Just answer the F*#king question

So, you can’t get your Acer laptop to keep a nice bright display. You set it nice and bright, then a few seconds later it goes dim again. You change the profile in EPowerManagement, goes bright then dark again. Doesn’t seem to happen all the time. Hair pulling time.

Unfortunatley, your looking at an issue with the EPowerManagement software, and probably the issue is when another user is logged on to the laptop at the same time. The solution … err .. sorry, there is none. You just have to uninstall the EPowermanagement option from Add / Remove programs. In all honestly, not a major loss.
