Title: Ubuntu 20.04.3 won't shut down
Post by: mahesh on Sep 20, 2023, 06:03 AM
I'm having a problem:I have been trying to turn off my PC for days, the monitors turn off, but the power supply and the processor cooler are not cut off.
The components of my PC are:

AMD A10 9700
Asrock A320MK
16GB Ram
500 SSD
Sentey 500w generic

I tried the next commands:
$ sudo shutdown -h now
$ sudo poweroff
$ sudo reboot
-----------------------------------------------------
$ sudo grub-update
$ sudo nano /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
Add acpi=force at the end:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force"
$ sudo nano /etc/modules
Add apm=power_off=1
$ sudo update-grub
-----------------------------------------------------

Update BIOS
I tried ALT+SYSRQ+REISUB
I tried ALT+SYSRQ+REISUO
I try booting an older kernel

Without any positive result.

P.S. Before the update it turned off normally. The same is happening with 7 other computers with the same components. I need help, thanks!!
