Re:Rattling sound in P620

2021-06-22, 0:49 AM

I received my P620 last week, and also have the rattling noise on the case fan (not the PSU or other fan; the one mounted to the case). Very annoying noise, as you can't help but hear it all the time.

 

Waiting for Lenovo support to let me know how we fix this...

I too have this PSU problem on my P620. Originally I thought the rattling is from the case fan. It turns out it's from the PSU.

 

The PSU is producing a very high pitch rattle noise.  Unfortunately when I login my Lenovo, it says that my system was sold with no warranty. 

 

Am I still eligible for the PSU replacement? 

 

Here's the proof of the noise (if you're sensitive to high pitch, just lower the volume) : https://www.youtube.com/watch?v=ykab-1u45kI

Hard to say what the noise is that you're referring to in that video.  As you moved down the system it sounded like the GPU was just as loud.  What GPU is installed in your system?

 

 

I'm not sure why the site would be saying that system was sold with no warranty unless it was a demo unit or something along those lines.  You'll be better off contacting support directly and trying to address that particular issue with them.

 

As far as I know, FRU stock for the P620 PSU should have been flushed some time ago to remove any units affected by this original problem.  So assuming you're getting a recent FRU from Lenovo (or Lenovo approved source), it should be OK.  The FRU for that PSU is 5P50V03189.  FRUs 5P50V03213 and 5P50V03212 will also likely be viable FRUs at some point as well as there has been some churn with the FRU PNs recently.  But 5P50V03189 is listed as the primary FRU from what I can tell.

I've recently found I have the same rattle issue.  I've reseated PSU, checked all cables to ensure nothing is hitting a fan blade but no luck.  It's a rattle that speeds up / down as the PSU fan goes up and is for sure not wind noise.  I've opened a ticket, but is there anything specific I need to do to have it addressed as I'm still under warranty?
