I can't take the credit for this but I wanted to share this info. Some of you may have already tried this but if not, it really does work and it's very inexpensive compared to the alternative of repair or replacement.
Everyone it seems on deployment has a computer of their own. You know as well as I do that the sands of the desert get into to everything. That's bad news for a computer. My PSG got a box of GLAD Press and Seal and put it over the entire keyboard area of his laptop to include the power button, etc. It did the trick of keeping the sand out of the keyboard and thus out the computer components inside.
As an IT Manager, I was impressed. Buy a rubberized keyboard for your laptop and look at the price tag that comes along with it. The nice part is when the press and seal gets dirty to the point you can no longer see the letters, simply tear off a new section and you're back in business. Press and seal does what it says. Try it.
