hi guys, My mba camera seems not working at all. I am not sure when it started, it was all fine last month. couple of days ago I had the software updated as prompted, and then today I found that the camera is not working not on my facetime nor skype and photobooth. It says that the camera is not connected. I googled and tried to do a smc reset. here is what I did:- -turned off macboook and connected to power. -pressed shift+control+option+power at the same time, 5 seconds and released -turned on power Nothing happened when I did the smc reset (no led light changed etc) and the camera is still not working. What should I do??
