Recently I have meet this problem that when I shutdown my laptop, Ubuntu auto restart and cannot shut down. I tried some methods around internet, and I see many other people have troubles with this. Then I want to share with anyone here who have the same problem with their computer. I tracked this for somedays, and I know that it worked successful)
( If I made this topic wrong, please remove it, thanks)
If you use hp probook then, it may happen to your laptop when using Ubuntu.
Please follow these steps to fix it.
I did this step before:
- Type in terminal sudo nano /etc/default/grub - then find a line GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" - Modify it to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" acpi=force apm=power_off
But it's not work because the next line they guide me is not found:
Type in terminal sudo nano /etc/grub/modules then add apm power_off=1 under line lp. Save and close the terminal.
Then I tried these two steps: And it worked.
Step 2: sudo update-grub
Step 3: Turn off wifi, wired network
hope that help.
