Solved Laptop failed to completely power-down

[usakhncit]

Hi
When I try to poweroff my machine by (shutdown -p now), it gets stuck at the end of power-down process and gives following message:

some processes would not die; ps axl advised

at that moment keyboard does not function and I have to hard reset my laptop by pressing power button for few seconds. Kindly guide me to solve this problem.
Thanks

There's a process running that refuses to die and it's this process that prevents the machine from shutting down. Before you tried to shut it down were you working on something? Had some zombie processes perhaps?

This is happening everyone so there is a process which fail to die every time. How can I investigate it? Thanks

Was I working on something? Not something special, just usual browsing, playing video on smplayer stuff like that. However, before shutting down, I always close all applications (usually with Ctrl+Q).
Also, if it is a zombie process then could it be occurring every time?
Would there be any log entry for that, so I can check which process failed to stop?
Thanks

Not necessarily. Something could have happened that caused a process to wait for a signal(3) that never comes.

The first log you should always check is /var/log/messages. Maybe there are some clues in there.

Running fsck fixed the problem.
