I've installed Linux Mint 13 (Maya) Ubuntu 12.04 based on 6 PCs for educational purpose.
Shutdown via GUI does not work at all. The PCs remain powered on, but no input is possible.... I tried to turn them off on a console but only one manages to power off after :~$ sudo shutdown -h now:~$ but not always... The others show the line [876.9876] Power down. forever until i turn them off manually.... After googling around I've found the kernel parameters noapic nolapic acpi=off ...but it didn't change the problem really, sometimes it worked, sometimes not... Then I read the posting from plum7500 (plum01) wrote on 2012-06-13: and i tried: :~$ sudo su - :~# shutdown -h now I use kernel 3.2.023 The PCs have nvidia cards...could this be the problem? I tried to switch from "nvidia current" to "nvidia current-updates" on one PC: After restart i tried to turn off via GUI and it did not power down... I tried again as root on the console, the PC had noapic and nolapic options as kernel parameters: Ctrl-Alt-F1 => console loggedin as user :~$ sudo su - :~# shutdown -h now ...and it did shutdown.... All PCs used to power off since Ubuntu 8.04 ....what can I do?

It often does not complete turn off the computer. The power LED and the LED of the bluetooth unit remain on. Also the fan is still running and won't stop. Shutting down the computer with "sudo shutdown -h now" using the terminal works fine. I am using a Dell Inspiron 1720.
