Comment 23 for bug 987220

I really wonder why people post comments stating they "are affected too", and don't click on "Does this bug affect you?" at the top of the page. Only stating that you are "affected too" this way will draw more attention to this bug. I've counted 6 comments, but only 4 votes.

I'm experiencing the problem occasionally on Lenovo Thinkpad X220. The system basically goes to halt, but doesn't switch off the laptop. I have to long-press the power button to switch it off. During the next reboot, I don't get a filesystem check - what makes me think that it was umounted properly.

In what log files can I check what the problem is? And what to look for?
