Hi

I don't know what has happened or if someone changed something but every single time I change the brightness control to 100% 2 seconds later it goes back to 0%. This is even when it is plugged in or has a full batter.

Even when i switch to that has brightness set to like 80% nothing happens. I went to maxium preformace profile and for some reason it is set to 0% when I change it to 100% and hit apply 2 seconds later it changes back to 0%.

Out side of windows(ie the login screen) I can change my brightness to 100% and it will stay there it's when I login it reverts to 0%.

I have the acer aspire 5100 laptop. Is there anyway someone could have changed something that makes this happen?

First thing first I would plug in an external monitor and see if it behaves the same way.

save the new profile first as something else, then apply that new profile. if you change a profile (e.g. high performance) then apply it you are just applying the original profile because you didn't save it.
