When shutting down in 12.04, either in terminal or GUI, the result is a laptop (dell inspiron M4300) which is still powered. I then have to hold the power button for 5 seconds to depower. It's just an annoyance, but an annoyance i wouldn't mind getting to the bottom of. Any thoughts?

Please try the boot parameters noacpi OR acpi=force. It's usually an ACPI incompatibility of some sort. –  izx Jul 11 '12 at 1:23

Try the following:

Modify /etc/modules and add:

 apm power_off=1

Edit /etc/default/grub and add this after quiet splash:

acpi=force apm=power_off

Finally update grub:

sudo update-grub
