Figure 4-3.  Screw Identification
The removal procedure illustrations provide the correct screw length in 
parentheses next to the screw’s label. Also, a graphic for that length screw is 
included in the illustration. Match the actual screw to the graphic in the illustra-
tion to check for correct length.CAUTION: It is essential that the correct length screw be used when
reinstalling a screw. Otherwise, hardware damage could result. Make
sure that the screw is properly aligned with its corresponding hole, and
avoid overtightening.

ZIF Connectors
Figure 4-4.  Disconnecting an Interface Cable
Some of the computer’s interface connectors are zero insertion force (ZIF) con-
nectors. These connectors are not removable, but they must be released to 
disconnect a cable from them. 
To disconnect an interface cable from a ZIF connector, follow these steps:
1. Insert a small flat-blade screwdriver or a chip-removal tool under the 
movable part of the connector.
If a small flat-blade screwdriver is unavailable, use a chip-removal tool to 
carefully pry up on first one end of the movable part of the connector and 
then the other end.
2. Pull gently upward on the movable part of the connector until it 
releases the interface cable.
3. Grasp the interface cable and pull it out of the connector.
To reconnect an interface cable to a ZIF connector, follow these steps:
1. Use a flat-blade screwdriver or chip-removal tool to open the movable 
part of the ZIF connector.
2. Orient the end of the interface cable with the ZIF connector, and insert 
the end of the cable into the connector.
3. While holding the cable in place, close the ZIF connector.
To ensure a firm connection, make sure the ZIF connector is completely 
closed. CAUTION: The ZIF connectors are fragile. To avoid damage, do not
apply too much pressure to the movable part of the connector.
