Ask Ubuntu Asked by Cuong T.Tran on December 30, 2020
I have a laptop (HP Probook 450 G0) with both Windows 10 and Ubuntu 14.04 in a dual boot configuration. Recently I upgraded Ubuntu to 16.04 using do-release-upgrade. After the upgrade, when I shutdown Ubuntu, the laptop automatically turns on after a few seconds (pretty similar to the problem in this thread Ubuntu 16 reboots seconds after shutdown). Windows 10 still works fine. I read a lot of boards looking for answers and tried some solutions, which are:
apt update
and apt upgrade
.grub
file with GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" acpi=force apm=power_off
.sudo shutdown -h now
, sudo poweroff -f
, etc…None of the above solutions work for me. The only solution that worked is to turn off WiFi using the shortcut button, and only then the computer will not start itself after shutdown.
Some side-notes:
Can someone help me with this problem. Thanks a lot!
Try this dude.
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
Type in terminal sudo nano /etc/grub/modules then add apm power_off=1 under line lp. Save and close the terminal.
Update the GRUB
sudo update-grub
Source: Reboot after shutdown (Ubuntu 14.04 (also 12.04); Dell latitude E7440)
It worked for me
