You can 'cold-spot' a motherboard etc. with compressed air, etc. A
compressed air 'cleaner bomb' will do. You might get enough effect just
by using a hose connected to the back end of a vacumn cleaner, blowing
on the suspect area.
Of course, any expanding gas will draw heat from the surroundings. So
you could use a CO2 fire extinguisher or even a butane refill for a
lighter if you want to live *really* dangerously*. (Of course, the
Goreacle would have you believe that you are doing more damage to the
planet using the fire extinguisher than by releasing a more complex
heavier more carbon carrying gas...but that's a different rant!
I presume that you have disconnected, cleaned and re-connected the
keyboard cable connector on this laptop?
