Screw Identification
When you are removing and replacing components, photocopy the screw placemat as a tool to lay out and keep track of the component screws. The placemat
provides the number of screws and the sizes.
NOTICE: When reinstalling a screw, you must use a screw of the correct diameter and length. Make sure that the screw is properly aligned with its
corresponding hole, and avoid over tightening.
