resume from suspend while connected to power results in roaring fans

[Darko Veberic]

since upgrade to ubuntu 20.10 my thinkpad x1 carbon gen5 resumes from suspend with a roaring fan. i have to make sure to start the resume while the power cord is not connected, let it wake up fully and only then connect the power cord. this is quite an annoying regression, still persisting in ubuntu 21.04, since there is no way to calm the fan noise except to do a complete shutdown and power on cycle (reboot still keeps the fan at max).

Does this still happen on 22.04?

[Darko Veberic (darko-veberic-kit)]

give me a day or two to test it.

currently i am actually annoyed with another bug: closing the lid does not trigger hibernation anymore; i have to explicitly choose hibernation from the menu.

[Darko Veberic (darko-veberic-kit)]

confirmed: the fan does NOT come up in full power anymore when waking up from suspend. thanks!
