Editing /etc/default/grub won't work until the grub config file is refreshed, either manually with grub-mkconfig or via the package manager after a kernel update. Also, /sbin/shutdown isn't the final executable—it's just a wrapper or symlink depending on the init system; I'm going to assume you're using systemd and the direct command would be `systemctl poweroff`. Whether you must run it as root depends on your system permissions.
This likely involves ACPI settings, causing a reboot instead of shutdown. You might attempt to trick the ACPI into thinking it's running Windows by modifying GRUB configuration and updating it. If problems continue, experiment with different ACPI values and ensure you refresh the GRUB setup regularly.
I observed two opening tags but just one closing tag. That looks like a syntax issue.
It's an HW-related concern only if it activates automatically after being fully turned off. You might test by checking if it shuts off when using a Windows USB drive. Don't forget to run acpi=force without any other ACPI settings, and also make sure to update the GRUB configuration.
It seems the system briefly powers down, but only for a short moment. My PC behaves the same when it restarts. I used Windows 8.1 before switching to Ubuntu, and it shut off without problems. Tomorrow I’ll format and reinstall Ubuntu to check if it works.
I made changes to the message as well, setting acpi to off just to confirm we’re testing everything. Edited January 12, 2019 by Guest
