Weird. My Macbook Pro 2.2 (10.6) just emitted a loud beep (like a pager sound on a telephone) upon startup and the "sleep" light was flashing quickly and then went to it's slower pulsation for a second or two.
I had pressed the start button for almost 2 seconds to start the machine i don't know why.
WTF?

Reset the SMC and clear PRAM.

thank you!
my fan was acting weird last night, too. It must be the SMC.
I guess I will clear the PRAM as well. Shouldn't be any harm in that. I took snapshots of all my keyb/mouse settings in case I lose them.

Also, check if Apple System Profiler reports all of your RAM. An extra beep on startup could mean one of your sticks failed the startup RAM test.

Normally if the RAM is bad, there will be three distinct beeps.

Holding the button on startup is a way of triggering a firmware update, if the right files are in the right places. The beep and the rapidly flashing light are the machine indicating that it's trying to perform a firmware update. Since you hadn't actually run a firmware update utility, there was no new image to flash and nothing actually happened. Nothing to worry about; just don't hold the power button on startup if you don't want your machine to do this.
