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:
- Turning off Wake up on LAN and Wake up on USB in BIOS settings.
- Running
apt update
andapt upgrade
. - Unplugging all USB devices before shutdown.
- Editing
grub
file withGRUB_CMDLINE_LINUX_DEFAULT="quiet splash" acpi=force apm=power_off
. - Trying other ways to shutdown like
sudo shutdown -h now
,sudo poweroff -f
, etc... - Reinstalling Ubuntu 16.04 (Erase and install from Live USB).
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:
- Sometimes after login I can't use any USB port (I tried with my mouse and USB flash stick).
- Even when I connect to the internet using an Ethernet cable, it still notifies/prompts me to connect to available WiFi connections.
Can someone help me with this problem. Thanks a lot!
fast boot
orquick start
or other similar Windows gimmick and see if anything changes.
