On my Lenovo Ideapad 3 and Lenovo Ideapad 3 Gaming 15ACH6 this occurs usually when I am browsing with Firefox.
Is this a known issue and what are some fixes?
The screen goes black and then it shuts down improperly like I hit and held the power button.
Edit: My Ubuntu 22.04 just hung and I did cat /var/log/syslog
and see a bunch of stuff stopped. I could move the mouse cursor but no mouse clicks nor keyboard. ctrl-alt-del and ctrl-alt-shift-"REISUB" did not work.
I skimmed cat /var/log/syslog
and did not see anything that stood out.

It just shut down again so I checked the log below, can anyone see anything that stands out? I also had a flash of green screen on a shutdown, not this time, but a few shutdowns ago.

. Without specifics, it will be darn near impossible to find a cause 😕
