I can't change it either by using the Fn and key on the keyboard, or through the power management thing in Windows. Can this be caused by the BIOS? I think this happened when I updated the BIOS.
I don't see how resetting BIOS settings would help if the screen brightness isn't working :\http://forums.toshiba.com/t5/Genera...33-Brightness-Setting-Not-Working/td-p/155026
This dude says to reset the BIOS settings. If I do that, what will happen? Will everything mess up?
