820-2850 backlight wont come back if mac is on and not used for a while
I have this board, backlight is OK while computer is on, but if you don't use it for like about 5-10, screen turns dim, this is normal. But when you hit any key or anything, backlight wont come back, although the screen is working and computer on. Any help?- Vinny
