Powering off a stuck computer

If you have ever experienced a time when your computer has frozen and nothing can be done with the keyboard or the mouse.  Well, some people unplug the computer, but there is a simpler way to shut down the computer.  All you have to do is hold down the power button until the computer shuts down itself.  I wouldn't recommend doing that unless it was your last option.  I say this because you have no chance to save anything that you have been working on.  Plus, don't power off your machine if the computer is doing something for you (the hard drive light is flashing).  But if the computer is frozen, it should be fine.

This is a simple tip that I will start with after being back from my blog vacation.
