Shutdown, Hibernate and cli shutdown, only reboot the system

Hello,

have you tried these in terminal

Code: [Select]

sudo shutdown -h now

Code: [Select]

sudo init 0

Code: [Select]

poweroffsudo is not meant to be needed for "poweroff" in 16.04, it may be worth checking this yourself.

for to force a shutdown

Code: [Select]

sudo poweroff -f

What happens when you press ctrl-alt-delete and select the Shut Down option?

ctrl-alt-delete in desktop does nothing. No response at all.

After loading of Linux boot and login is fine. None of the above work to shutdown the system. If I press and hold the power button the system will power off..... BUT..... as the power button is released the system boots back up.

Any ideas.... I have followed most suggestions and not found a fix. I do not believe it is an OS problem... seems to me a BIOS problem. There seems to be no setting in the BIOS that will prevent the reboot.
