Weird clicking sound from speakers on T-20

[dman535]

I have had this problem for a while on my T-20. It is best described as what sounds like someone dialing a phone number on pulse through the speakers. I hear it faintly anytime the machine is on. I have a docking station and a set of external speakers. I have tried to plug it in right through the audio out on the laptop but this noise is still there.

It doesn't seem dependant on cooling fan, hard disk or anything else. Anyone have an idea what it could be ?

Thanks

sounds familiar, it is the power brick that emits hich frequency click sounds, which are collected by the analog audio cable.

I have the same problem, bought expensive, fully coated audio cables which solved the problem a little bit.
