Recently, but I don't know after which operation or update I've encountered the following problem with Ubuntu: when I shut down the system, the laptop doesn't power off, the power light and fan still work.
I've searched this forum, but the solutions I found didn't work.
First I tried this solution but nothing changed, then I tried to find out at what point the system would shut down using the command in the terminal
journalctl -b -1 -e
this is the output

As far as I have been able to understand, all the switch-off targets are reached, but the fan and the ignition light do not switch off. The only way to actually shut down the computer is to force the shutdown with the power button.
No problem with W10.
The laptop has the following specifications:
- O.S.: Ubuntu 20.04.3 LTS (dual-bot W10);
- Brand and model: Levono Yoga 510-14AST
- CPU: AMD A9 7th gen.
How can I proceed? Is there any procedure I have not considered?
A sincere thank you to anyone who would like to take the time to solve the problem!!!
