Anleitung Zusammenfassung
To assist in keeping track of the screws, use a tackle or pill box as a storage device. A location template (see Figure 4-19) is useful as a label for the storage device for the screws. The information in parentheses ( ) denotes the screw name(s) called out in the figures. Be careful not to scratch the computer plastic case by allowing the screws to get between the disassembly surface and the plastic case. Also, to prevent case scratches, a soft padded work surface is suggested.
