T41p 'klank' sound, not the hard disk

I have a T41p, and there is this occasional 'klank' sound, like a metallic noise, and thinking it may have been a hard disk beginning to go bad, I contacted IBM (Leveno) and got a replacement HD under warranty.

However, still the same noise exists, disproving it may have been the heads of the hard disk, etc.

It seems to be at the top left area of the keyboard...and it only happend once in a while.

I'm curious if anyone else may be experiencing this noise and if so, what it is.

My warranty expires in 7 months.....and if needed, I'd like to get it fixed while it's still free.

In my experience, the harddisk will once in a while emit a "clank". This is quite common, and I suspect it has more to do with the reader heads stopping than an actual error being present

Someone please correct me if I'm wrong...

Just double confirm that raabjerg is correct.

Welcome to the Thinkpad Forum

I have heard that sound, rarely, and it is indeed the HDD. Most often it resets the heads for thermal recalibration sometimes (although this is a very infrequent occurance on modern HDDs).

I disagree.
Are you all saying it's something inherent to a Thinkpad?
I've never in my life ever heard it in 15 years on anything, except a bad HD (going bad).
I never heard it before the last 3-5 months.....never before.

How about this?
The shock/active protection maybe?

In any event, it in no way can be a brand new hard disk, 1st the hard disk is on the right side, the klnak is from the left side.

Fan, heat, contraction, expansion, CPU?

No, it isn't inherent to a Thinkpad. It is a side effect of a mechanical process, although much less so nowadays, of modern HDDs. If I take it correctly, it is a loud "klank" that is far louder than head parking; that is the sound that I have heard on a variety of laptops, including Thinkpads, usually when they are in the "newer" stages of ownership and are fresh out of the box, which coincides with the 3-5 month timeframe and what I have seen.

Just a thought - to see if it is indeed the harddisk, try removing it, leave the computer on for a couple of hours, and see if the sound still persists...

If it's a quiet sound I really think it is just the head parking due to the active protection system. Yeah, other laptops that you have had may not have done this.. because they'd rather your hard drive just fail if you drop the laptop
