The option of last resort is to unplug it. Also, on most computers built in the last decade or so, holding in the power button for several seconds will generally shut the power off (this is not necessarily any better than unplugging it, but usually the power button is easier to reach).
You should try rebooting it. (Turn off the computer and turn it back on.)

With most computers, you should not plug or unplug the power unless you turn off the computer, first.
