Computer won't shutdown

[shaggy_160]

When I shut it down the screen goes black, and the keyboard LEDs are turned off. Even the power button on the tower is not lit, but I can hear sound coming from the tower like it is still running. I have to pull the plug to turn it off. I have a system 76 meerkat nettop with Ubuntu 9.10. One day I hibernated my system and I think this is how the issue began. I am new to Linux so I have no idea what the problem is.

Do you have any CIFS or NFS shares mounted when you power it off? Up until 9.10 I found Ubuntu would hang forever when I tried to turn it off with these shares mounted in the same manner you're describing (black screen, etc..).

Thanks for the reply. I'm sorry I haven't replied but I have two jobs and almost no free time! I am still learning how to navigate these forums. In response to your question, I don't think I have anything mounted. The computer's power button and the keyboard look as if the computer is off, but I hear a sound coming from the tower like it is still running. When I push the power button to turn it on, it won't do it. I have to unplug the power cord and to plug it back in before pushing the power button in order to turn it on.

The next time that happens, let it run for a few minutes, then shut it down. Then turn it back on, open a terminal (Applications > Accessories > Terminal) and run this command

cat /var/log/syslog >> ~/Desktop/syslog.txt

This will create a file on your desktop that you can attach to this thread. Also, make note of the time on your system clock when the computer comes back up.
