I'm using HP Elitebook 1040 x360 G8 with Ubuntu 22.04 LTS and found out that system is not waking up after being suspended despite that power is definitely switched on and fans start spinning - screen stays turned off and laptop not react on any keyboard combinations. That's the last messages in journalctl output:

Yeah, I've found out issues with suspend mode is quite common for HP laptops for almost 2-3 years already. But still wondering if there will be some solution one day. Or maybe somebody already have workaround for such case?
journalctl --system --boot=0 | egrep -i "suspend|resume|entry|exit"
? It probably is diff. than what you posted and should also show a message about the why. My bet? the system is too new :P – Rinzwind Jun 21 '22 at 18:35
