Screw list
NOTE: When removing screws from a component, it is recommended to note the screw type, the quantity of screws, and then
place them in a screw storage box. This is to ensure that the correct number of screws and correct screw type is restored when
the component is replaced.
NOTE: Some computers have magnetic surfaces. Ensure that the screws are not left attached to such surfaces when replacing a
component.
NOTE: Screw color may vary with the configuration ordered.
