Occasional single high-pitched beep

Every so often I hear a single, short, high-pitched beep emitted from my MacBook Pro. It doesn't sound like it's coming from the speakers--at least it isn't a system beep, but perhaps a hardware beep?

Any reason to be concerned about this?

MacBookPro2,2, Mac OS X (10.4.10), 2.33 GHz, 3MB

No flashing light. I don't think it has to do with the RAM. And the beep occurs well after the startup anyways.

Funny though, it has been quiet for the past few hours. I'll keep posting updated if it starts to make noises again. Then hopefully I will be able to see if anything in particular brings back the beeps.

No after market RAM. Order direct from apple.com with no 3rd party hardware. The machine does not crash and everything seems to be functioning as normal. It is a single short beep that is NOT emitted from the speakers but something else internal. There is not a particular action that causes the beeps to occur.

Does the sleep light flash when it makes this sound ?

Beeps are usually a ram issue. Have you installed after market ram? Does the machine crash? What are you doing when these beeps occur? Is it just one tone? Is it a long tone or a single short beep?

Watch and see if /Utilities/Console/system.log shows anything at the time it beeps ?
