Found this through Googling, and have a few things to mention.
If this is the same problem as mine, the media bar is not lit up, and none of the buttons seem to work. Additionally, the SCROLL, CAPS, and NUM icons do not light up when I enable their respective...things. Locks.
Additionally, the built-in camera ( 2.0 Megapixels. :U ) doesn't seem to work. I ran CyberLink and it just couldn't detect it.

Any suggestions that don't involve wiping out everything I've done so far?
