Figure 4-3. Screw Identification
CAUTION: When reinstalling a screw, it is essential that a screw of the correct length be used. Otherwise, hardware damage could result. Make sure that the screw is properly aligned with its corresponding hole, and avoid overtightening.
The illustrations in the following removal procedures provide the correct screw length as part of the screw's label. A graphic for that length screw is also included in the illustration. Match the actual screw to the graphic in the illustration to check for correct length.
Some of the computer's interface connectors are zero insertion force (ZIF) connectors. These connectors are not removable, but they must be released to disconnect a cable from them
CAUTION: The ZIF connectors are fragile. To avoid damage, do not apply too much pressure to the movable part of the connector.
To disconnect an interface cable from a ZIF connector, follow these steps:
1. Insert a small flat-blade screwdriver under the movable part of the connector.
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 small flat-blade screwdriver 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.
