Ok, I can confirm now that the Xbox has been beeping. It did it again last night just as I was about to turn it off. It's emmitting a fairly long (1/2 second) beep that sounds like an alarm of some kind. But the unit still continues to function for at least a short period of time afterward. Although, I've not had it on more than 15 minutes after hearing the beep.

My guess is this is some sort of warning about temperature? But the manual doesn't say anything about it and none of the lights have turned red. I wish I could get some idea of what is going on here. The unit is fairly new and I could still take it back if its faulty. I don't really want to load up my hard drive with saves and arcade games and then loose them all by replacing the unit.

When you send your xbox in, you take the hard drive off, you keep all your profils, saves and games on it. I think mine's beeped before but I've never had any problems.
