Thinkpads Forum

i will try to describe my problem:

got my new laptop yesterday. i now have a lenovo t60p (2007-FBG) with external speakers connected. in the right speaker i hear a very very low (and very very annoying) kind of high pitch electric click-click-click noise every 5 seconds or so. all the time. ALL THE TIME! it wont stop until i turn the computer off. and then it comes on as soon as i turn the computer on again. this is very irratating because even if i play music loud it comes thru.

i've tried reinstalling the soundcard just about a thousand times. nothing changes. i've tried disabeling microphone input, cd-player, syntheziser and everything else in the sound device manager - but nothing helps! even if i turn volume completely off it is still there. all the time. click-click-click.

it is seven very quick "electric" clicks.

what the f can this be? and more important - how do i fix it??
please please someone help me i am going totally mad over here!!

and it is definately not the speakers! ive tried them on several diffrent computers and none have had this horrible defect.

(excuse my poor english, i am swedish)

come on guys help me out here!

Sorry mate --

I'm sure there are plenty of people reading this, but they have no idea how to help. It's obviously not a software issue (I think) -- in that the sound is not being generated by software (because if u turn the master volume off, it is still there).

I'm guessing that it is some hardware change which is occurring periodically (e.g. CPU clock changing, hard disk read, etc.) that is not properly electrically isolated on your machine. Lots of these kinds of noises come through. There was recent mention of the sound that occurs when you move the mouse -- this sound seems to come from an actual capacitor, rather than through the speaker output (this happens on mine). I have hooked up my headphones to my machine and I don't hear the sound at all on either AC or battery.

I guess what I'm trying to say is that I think there is probably very little that you can do about it -- which is more than a little disappointing.

That said, I just had a thought -- Do you hear the sound when you're on battery? Are your speakers powered separately? Perhaps it is the AC adaptor switching on and off?

thanks for your reply astro!

yepp, i've tried it batterypowered - same thing.
i don't think that there is anything wrong with the speakers they are real studiomonitors from mackie - which i tried just yesterday on a acer laptop without this problem. i'm thinking the same thing as you are. probably some bad isolating issue.

i am about to purchase an external soundcard (rme multiface ii) and hopefully this will disapper then. but i was just praying someone would have come across this kind of error before and could guide me thru it. kinda hoped i could get it fixed before i buy a soundcard for $1000 so that i dont stand there with that clicksound with the external soundcard as well...

jesus christ i think i actually solved it!

disabled the ir-port and the internal modem, and now its gone!
i dont use them anyway so it not a big thing...

JIPPIE!

so much for the superior build quality of Thinkpads,
and the advertised "new" HQ audio hardware on the T6x models.

I just read this thread. this weird sound(the ir is searching for other ir-hardware around itself) is there already since the t2x-series.
yes, just disable the ir port.

and yes, i think it is still a bug.
