It might also be worth mentioning that you can ALMOST always force a
system to power down by pressing and holding the power button for 5
seconds. This has always worked for me and is pretty fundamental, but
it is claimed that there is an exception to every rule. (Some systems
allow this to be disabled in BIOS, though.)
In any case, this is easier than pulling the battery.
