My new 15" AlBook 1.25 makes a strange "tick" sound every few minutes. Its pretty quiet and I only notice it when I'm working in a quiet room. But its there.

I think its coming from the right side of the case and I believe it "ticks" even with an audio plug in nthe speaker jack.

Has anyone else experienced, heard about or solved this?

Could be an instance of the infamous 'sizzle'... if you do a search you can get all the info.

Or, could it be HD heads parking?

It possibly could be the HD. I know there is some software which causes the head to continually cycle, older HP software to be precise. A tick noise is never very good.

Depending on the loudness of the tick, I'd say it's either nothing to worry about (just the HD parking/unparking its head), or something to be very worried about (thrown bearing in the HD or other nastiness).

More than likely, it's the former, not the latter, since your machine is still in a functional state.

Some HDs will do that regularly. If it happens regularly every few seconds, then it's probably normal. I have an HD that's been doing that all it's life and it's about 10 years old now.
