When I want to turn off my laptop It doesn't power off. The screen power off, but the laptop still making noise, and the work indicator is on. It powers off when the battery becomes empty. I don't know what to do. Can't you help me?

  • Could you edit your question to include the brand and model of your computer? This will help identify if it’s a known issue. If there is any error message or text on the screen when the notebook is shutting down, knowing what it says will also help 👍🏻

  • Can you report if opening a terminal and typing sudo shutdown now (and your user password when prompted) does a complete power down?

You can shut down from the command line (terminal) you will need to be root to do this;

sudo -i
shutdown -h now

sudo -i - changes you to the root user, you may be asked to confirm your password.

shutdown -h now - this issues the halt command 'now' which should cause the OS to go through the shutdown process. See https://linux.die.net/man/8/shutdown

If there is a problem, you should see output on the terminal window, and in /var/log/syslog

If you are not able to shutdown in the GUI, possibly your user does not have permission, see https://unix.stackexchange.com/questions/85663/poweroff-or-reboot-as-normal-user

I had the same problem and it was due to the Linux kernel upgrade to version 5.11.0-41.

You can try and confirm if that's the problem by booting to an older kernel version (5.11.0-40) in Advanced Options of GRUB.

If that is the case, you can definitely fix it by downgrading to version 5.11.0-40:

sudo apt remove linux-image-5.11.0-41-generic linux-headers-5.11.0-41-generic

And then reboot.
