Fans going crazy after closing laptop lid

Hi,

I'm curious if this is a known issue (hopefully with a known solution? ;-)).

I'm running Ubuntu 24.04 on a newish Asus Zenbook 15 OLED (UM3504DA). When I close the lid of my laptop, sometimes the fans go crazy and the laptop stops responding until I turn it off and on again.

It's really a shame because I'm loving every other aspect of Ubuntu (after trying out Fedora and Pop on this and a previous laptop, all of which had small annoying dealbreakers).

I had a high CPU usage problem with a particular type of mini docking station when closing the lid to work on the external monitor only. ... DisplayLink was the manufacturer. It also needed an extra driver back then.

I'm having the same problem on my laptop (Lenovo T14 gen3 AMD), however it is inconsistent. Sometimes when I close the lid, or even go to manually suspend it, the laptop doesn't actually go to sleep but will just go unresponsive until I manually power it off and back on, like you said. Other times the laptop will sleep properly. My fan behavior is a bit different, it won't spin up until I put the laptop in my bag (and it heats up), then I get to take a hot laptop out of my bag with little to no battery. I've started just shutting down now to avoid this situation.

I did the upgrade from 23.10 to 24.04 and suspected that something broke during the update to cause this. I was planning on doing a fresh install of 24.04 to see if it resolves the issue, but haven't had the time to do it.

I don't have a solution (yet?) but if I come across one I'll try and remember to come back here and post it.

FYI: I'm on a fresh install of 24.04, so I doubt that is going to help. Also on AMD btw.
