My sister has a ACER Extensa 4620/4620Z Series Laptop and it has a problem with the built-in cam a more detailed description. The cam worked just fine one day after that day it stopped working. Also the USB 2.0 Ports don't work anymore they stopped working the same day the cam did. BIOS Version is 1.6 I think or close to that it isn't using Windows Vista cause she prefered XP Home Edition. I have been trying to find out how to fix the problems for about seven weeks and found nothing to help me. Please let me know if you know what to do with the computer, Drivers, BIOS updates, ETC.
