Service a keyboard: Service a mouse or a trackball:
 * 1) Disconnect the keyboard from the computer and turn it upside down. Remove the assembly screws and pry apart the top and bottom housings.
 * 2) Carefully lift off the top housing and either shake out or blow out debris with canned air. Use an electrical contact cleaner to remove any residue or corrosion.
 * 3) If the keyboard still doesn't operate properly, replace it.
 * 1) Unplug the mouse and turn it upside down. To remove the trackball, press the ball-cage housing cover clockwise or forward, depending on the model. (Most mice have instructions and arrows on the bottom.)
 * 2) Remove the track ball and clean it with a lint-free cloth dampened with denatured alcohol. Allow to air dry.
 * 3) Scrape any plaque from rollers on the inside of the ball cage and swab them with denatured alcohol. Use compressed air to blow out dust and debris from the interior.
 * 4) Reassemble the mouse.
