I had problems with my built in webcam, whenever I moved the screen it would shut off. Today while on a skype call I tried a video call and the webcam stopped working but the cams light stayed on. Device manager says there is no cam. After a few restarts the problem persisted: web cam light is on andit doesn't show on device mananger.
I remember that once I solved a similar problem in another laptop by draining the static from it.
So I took the AC and battery off, pressed the power button for 30 secs and...
now I get a dead black screen and get 5 beeps (the first one louder than the others) like 1 sec apart and it repeats itself. The only way to stop it is to take the battery off.
I found that error code means a possible faulty cmos battery or RTC but unless it got damaged BECAUSE of the static drain I found it hard to believe. The computer is 1.5 years old.
Any suggestions>?
Thanks for your help
