Dust damage

DUST DAMAGE Army friends who have used laptops in Afghanistan and Iraq report serious problems with the fine dust that infiltrates everything and damages moving parts. Somehow even the contacts for keys in the keyboards become disabled. Covering the keyboards with membranes slowed the damaged, but didn't stop it. Users considered the equipment expendable because of dust damage and no solution was suggested. I have no idea how to cope with such a problem, but can see how it could pose a major problem for many areas where laptops will be distributed.
