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 surface when
replacing a component.
NOTE: Screw color may vary with the configuration ordered.
