Can't shutdown properly

Basic Help & Support
1

When I try to shut down, my screen turns off, but my desktop doesn’t turn off until I force it to power off. This happens both when shutting down with the UI and in the terminal with systemctl poweroff. This is especially concerning assuming that I need to safely shutdown my computer for driver and kernel updates.

There are quite some points to look at.

Below a list of possible causes + Todo

Problem                                    | What You Can Try
------------------------------------------|------------------------------------------
BIOS doesn't work well with Linux         | Check for BIOS update on ASUS website.  
                                          | Try adding `acpi=force` to boot settings.

Fast Boot is causing issues               | Go into BIOS (press DEL at startup).  
                                          | Turn off “Fast Boot” option.

Power-saving settings are wrong           | In BIOS, look for CPU C-States.  
                                          | Try turning them ON or OFF.

Hidden Intel features cause problems      | Look in BIOS for "Intel ME" or similar.  
                                          | Turn it off if you find it.

Something hangs during shutdown           | Open terminal and type:  
                                          | `journalctl -b -1 -e` to see what failed.

Linux version is too old for your CPU     | Install a newer kernel (like 6.4 or 6.5).  
                                          | In terminal: `sudo mhwd-kernel -i linux64`

Startup settings are wrong                | Edit the file: `/etc/default/grub`  
                                          | Add: `acpi=force` or `noapic`, then `sudo update-grub`

Linux doesn't force shutdown properly     | It might miss a timer or crash silently.  
                                          | Try adding `nowatchdog` to boot settings.

Graphics drivers not shutting down clean  | If you use Nvidia or Intel graphics:  
                                          | Try using open-source drivers instead.

External hardware causes freeze           | Unplug USB drives, gamepads, etc.  
                                          | Then try shutting down again.

Hope this gives some directions to look at.
