Touchpad – What is the easiest way to disable the touch pad on a laptop?

What is the easiest way to disable the touch pad on a laptop?

I have a laptop which lacks a means to turn off the touchpad with a simple Function key sequence.  I would like to disable the touchpad so that it stops detecting movement when I am typing.  This is quite an annoyance as it sometimes results in deletions of sections of a sentence I am typing.  Right now I have a thick piece of paper over the top to decrease the sensitivity.

Any other suggestions on how to do this?

Solution:

Original post isn’t real clear on if you need something that can be quickly turned back on or not.  Typically, the connector from the touchpad to the mobo is easily reached under the keyboard.  You could unplug it as long as you don’t need to be able to turn it on/off on the fly (and you’re not worried about warranty/possible accidental damage concerns).  Obviously, don’t do this unless you’re quite certain of what you’re doing, etc.  Poking/proding the wrong thing could cause permanent damage.  Insert additional disclaimers here, etc.
