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.
