When your computer is plugged in to a electrictal outlet the screen is brighter then when running on battery power. That is unless you are on my computer. A few months ago I noticed that when I was using the computer on battery power the screen became brighter then when plugged in to the wall plug. I bought a new power cord (with transformer) thinking there was a short or something. This did not help. Has anyone heard of this and know how to correct? I would appreciate any help with this problem before I go blind.
Thank you Toni Lucas
