[UPDATE] different conditions
Hi all,
after the 2026-08-12 stable update, for two days in a row I experienced this strange behaviour:
after leaving unattended the machine for more than 1 hour (lunch break) I found the machine powered off.
I disabled in plasma everything related to power saving.
Looking alt the logs I don’t see anything strange (but maybe I don’t know what to look for)
I’ll verify if in the next days the problem reappear
What can I look for?

I have an old PC case with its power button on the top as well (not in use, need to fix the motherboard).
