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. Table 1.
