This old laptop crashed too many times & my pal installed Windows 7 and all is good. I am not so PC savy but get around enough to screw things up. All is good except I notice thatthe brightness control for my screen seems to be stuck in low power mode and I like it bright due to being half blind. I can't get it to function by the "fn" key & up/dn control. I have gone into the settings and unable to change it. Can anyone help?
