[Surface Pro 9] Fan still running during suspend #1445

Open 3xfc opened 1 month ago

If I run a task that gets the fan spinning and suspend the system, the fan keeps running for a while until the device cools down. The fan always turns off during standby on Windows.

Environment

Hardware model: Surface Pro 9 (Intel)
Kernel version: 6.8.8
Distribution: NixOS

Nothing seems to stand out in the dmesg log.

I am also experincing this issue

Suspend appears to work, the screen goes black and Fn keys don't light up. However the fan continues to run.

This may or may not be related, but I am experiencing bug 1442 as well. https://github.com/linux-surface/linux-surface/issues/1442#issue-2284496806

Environment

Running Fedora 40 on a Surface Laptop Studio 2

uname -a Linux fedora 6.8.8-1.surface.fc40.x86_64 #1 SMP PREEMPT_DYNAMIC Tue Apr 30 08:25:23 UTC 2024 x86_64 GNU/Linux Relevant Journalctl May 24 12 10 56 fedora.txt

Also having that problem on newest ubtuntu lts. Sometimes the typecover restarts when waiting a little bit and detach and reattach to the (in my case) sp8 but this behavior is not reproducible.

I thought there might be some connection between the difference in hibernation and standby to this problem, since I've read to enable hibernation you'd need a swap partition. I wanted to test if using hibernation solves the problem.

I'll try around later in the eve and if I success I'll let you know.
