Offhand two (2) options to address your concern:

• use a small external USB or PS/2 keyboard;
• order a replacement keyboard. Pls reference 1, 2 or 3.

Im afraid to suggest this but if his/her hands were wet which I suspect might be it the keyboard might be killed by the water but only selective keys are working.

Since this is a Compaq do you have HP's ADP plan for it?
If you do they will fix that for free. Mind you it will take 2 weeks.
