I have a lenovo something or other (got it as a christmas present, not sure of its actual make) and just today when I turned it on, the screen brightness was a bit low so I hit the fn button and up arrow (the keys to up the brightness on it) and it wouldn't move up from the first notch up. I tried manually adjusting the scroll bar, tried going into the display settings, nothing that I could find would work. Does anyone at least know what's wrong if not how to fix it?
Also, if it's any help, it went to sleep while updating yesterday and a guy at the computer ship had to take out the battery, but it would adjust after that, only now after I've shut it down does it fail to change.
