I own an ibook 500 G3.
Lately my display gets brighter and lighter without me changing anything.
Like someone is playing with the dim switch on a light fixture.
I had this problem before, few months back, so I re-installed my OS and that seemed to help.
I'm just worried that one day the screen will die or it means something else.
I backup all the time, but I'm worried about losing important information and not being with a computer at this time.
I don't have applecare, and it's been 3 years... but if it died that would really suck at this time as I'm a writer and use my computer all the time.
Anyway, anyone else experience a similar problem with the display?
