Bad news - the BIOS update only fixed it for a few days, and the webcam stopped turning on again.

Can you think of anything else that might be causing this problem? I haven't had time to try fixing it until now, but I'm starting to think it's a hardware issue... I just hope it's something else because I don't know if the webcam is covered by my warrantee and I don't feel like going to all the trouble to get it serviced.

Any help would be greatly appreciated.
