Set the keyboard upside down on a towel. Let it dry overnight and it should be fine. If the keyboard doesn t respond properly after a soaking incident, call in a professional. The mouse cursor moves on the screen when you slide the pointing device on a padded surface. When you notice that the mouse cursor does not respond quickly, it s time for a cleaning.
Most mice have a small cover that protects the ball hidden in the housing.
Remove the cover by twisting it, shake out the cracker crumbs, and wipe the ball clean. You should also blow gently into the ball-cage or spray canned air into the opening. Replace the ball and reassemble the mouse. Your computer, especially older models, may contain external drives. The read-write head in each drive scans the disk or tape as it reads and writes data.
