Changing the disk to AHCI in BIOS allows my 9310 to reach C10, fixing the sleeping heater issue.

I’m running linux kernel 5.14.3 for the QCA6390 support as my laptop is the Windows edition.

I have the same machine for work: early this year sleep mode was not very useful (it wouldn't pass a weekend), but after an Ubuntu upgrade a few months ago it got much better. Yet, it's still worse than my 6 year old ThinkPad.
