computer doesn't turn off after shutdown

Asked by TheKey84 on 2010-11-21

Hello,

I have an installation of Ubuntu 10.04 server. That Computer should shutdown automatically in the evening via a cronjob. But since some time it doesn't turn off completely after shutdown. When I use halt, everything looks normal at first. The last thing it says is: System halted. But power supply, monitor and fans keep running.

I already tried acpi=force, but this didn't work. Some other parts of ACPI stopped working also. For example, there is no path /proc/acpi.

Thank you for your help.

Hi

Have a look at the 'shutdown' command and try using the option below:
-h halt or power off after shutdown
-H halt after shutdown (implies -h)
-P power off after shutdown (implies -h)

So for -P command would be:
sudo shutdown -P now

It sounds like your system is halting but not powering off.

Hope that helps.

Andy

Hi Andrew,

I'm sorry, I already tried the shutdown command. It didn't help.

But thank you anyway.

Problem solved. ACPI was disabled in BIOS-Setup.
