    6. Remove any PC Cards.   
    To remove a PC Card from the top connector (see Figure 4-6), press the top 
    eject button (identified by an arrow pointing up) twice. To remove a PC 
    Card from the bottom connector, press the bottom eject button (identified by 
    an arrow pointing down) twice. If you are removing a type III card, press the 
    bottom eject button twice.
    NOTES: The first time you press an eject button, the eject button itself pops 
    out. The second time you press the eject button, the PC Card is released and 
    extends slightly from the slot.
    Grasp the end of the card, and pull it completely from the slot. Then install 
    one or both of the blanks provided with the computer to protect the PC Card 
    connectors.

    7. Remove the hard-disk drive assembly.
    Turn the computer over and remove the small rubber covers over screws 
    HD1 and HD2, then remove the screws. Pull the hard-disk drive straight out 
    of the computer (see Figure 4-7).    CAUTION: When handling the hard-disk drive, handle it gently and
    don’t bump or drop the drive. Rough handling of the drive could
    induce failure or loss of data.
    CAUTION: When the hard-disk drive is not in the computer, protect
    the drive from exposure to static electricity by storing it in a hard-
    disk drive case.

    ZIF Connectors 
    Some of the computer’s interface connectors are zero insertion force (ZIF) 
    connectors. These connectors are not removable; they must be released to 
    disconnect a cable from them.  
    To disconnect a cable from a ZIF connector, follow these steps:  
    1. Insert a small flat-blade screwdriver or dental pick under the movable part 
    of the connector (see Figure 4-10).
    For most ZIFs, carefully pry up first one end of the movable part of the con-
    nector and then the other end. Some ZIFs (keyboard connector on the main 
    board) may need to be lifted in the center. 
    .
    Figure 4-10.  Releasing a ZIF Connector
    2. Pull up gently on the movable part of the connector until the cable is 
    released.
    3. Grasp the cable and pull it out of the connector.
    To reconnect an interface cable to a ZIF connector, follow these steps: 
    1. Use the flat-blade screwdriver to open the movable part of the ZIF 
    connector.
    2. Orient the end of the 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: ZIF connectors are fragile. To avoid breaking the connec-
    tors, touch them carefully. Do not apply too much pressure to the
    movable part of the connector when opening or closing it.
