ThinkPad X1 Extreme "Electrical" Noise

2019-03-10, 0:16 AM

I got mine X1 Extreme back in December 2018 and it's been making this strange electrical type noise similar to how a regular hard drive sounds while it's plates are spinning. It doesn't sound like the fans. It is not really loud but it does vary in loudness. When it's at its loudest, I can hear it while typing in a quite room. Other times, I can only hear it if I put my ear next to the keyboard. I read some posts here about the coil whine. Is that it? Is it normal? Any way to get rid of it?

Reading the following article I am quite sure the noise I have is the coil whine: What Is Coil Whine, and Can I Get Rid of It on My PC? - How-To Geek. I can only assume that there is no good way to get rid of it completely in this laptop or is there?

I have the same issue.  Not thrilled with this and another issue of freezing several times an hour.  I'm going to request a replacement tomorrow...  A lot of time wasted.

Hi, could you please share the result of the replacement? Have you resolved this issue? My X1E has the same issue but I'm not sure whether it's a feature of X1E or a bug of X1E. Thanks!

I submitted mine for repair, and the service team replaced the CPU fan, to no avail. I am going to record the sound/video and upload later, so others can compare.

Spectrum analyzer from the microphone on my phone and tablet show a clear pitch following some pulse train, based on whatever circuit is under load I can only imagine. 3008-3012 Hz or so.

I have an X1C5 20HR and it also has excessive coil whine. In faze2's recording I can hear a quite similar vibe. <:

 

In my case the coil whine sounds like this: https://clyp.it/v2ky42w4 

 

Spectrogram attached. It is the loudest over the "g" key, right where the CPU is.
