Ok, the model number would probably help you guys help me. Where can I find that? I looked on the bottom, but it is hard to tell which number is the right one. Oh! I can see the serial number, would that help?
Anyway, the real problem is that I can't turn the brightness up or down. Sometime it will flicker at me, but usually it just stays really dim. It's really frustrating, since a lot of the places I use it are fairly bright. I have tried checking if it will dim to save battery, and I have held down the "Fn" key while pressing "F6" or "F7." If anyone can help in any way, that would be great. Thanks in advance!
