4.0.2 can't shut off

I use v. 4.0.2 on my laptop computers. All works fine (except wireless, but that's another topic). When I try to exit and shut off my computer, it doesn't work. The program logs off fine, but it stalls at the end and I have to press the button on my computer for seconds to shut off. It seems to me it stalls afer "send the term command" and "sending the kill command".

I have two modern laptops (Toshiba 3.0 ghz and HP centrino 1.7) and the problem occurs on both computers. v. 4.0.2. DOES shut off on my desktop pc.

Is this a known error with laptops and, more important, is there anything i can do ?

Maybe I have found the solution: I use a USB stick for a permanent image. I have removed the USB stick before the final part of the shutting-off process. Now the laptop computer did shut off. Maybe the error was in the USB stick. Is this a common issue ?

if you're not booting from usb stick (not sure what you mean by 'permanent image')

Before logging off try;
sudo umount /dev/sda
or sdb/c/d

If there's an issue - try Logging off, instead of shutting down....then use the same command
If successful, use shutdown now orinit 6 when you're down in a VT (Shell) only (text mode) - the result of Logging off

Perhaps you need to bootup using apm=off or similar cheatcode

That's sending the Terminate and kill signals respectively and is likely having issue with unmounting the USB device before shutdown

While booted normally - post output of;
mount and cat /etc/fstab and fdisk -l
