ZIF Connectors
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 (see
Figure 4. Disconnecting an Interface Cable
NOTICE: 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, perform the following steps:
1. Insert a small flat-blade screwdriver behind the movable part of the connector.
2. Push gently sideways 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, perform the following 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.
