the last BIOS is actually A11
which is the one i'm running right now, but my webcam doesn't work anymore (no blue flash when the other USB devices get called up by the OS, doesn't appear anywhere in the devices lists nor in the diags)
it was available when i got the laptop a few weeks ago but as the newest BIOS is a recommended download on Dell's support site, it got downloaded & installed. after that the webcam wasn't there anymore.
i tried other available BIOSes (A06, A09) but none makes the webcam visible again.
thus A07 seems a reasonable (last) thing to try before having to replace the webcam, no?
