1 keyboard flex cable
6. Use the pull tab to pull the keyboard flex cable up from its connector on the system board.
The keyboard is now disconnected from the bottom case.
Replacing the Keyboard
1. Replace the hard drive .
2. Place the keyboard face-down on the palm rest, with the keyboard flex cable pointing toward the back of the computer.
NOTICE: To avoid damage to the connector pins, press the keyboard flex cable connector evenly into the interface
connector on the system board, and do not reverse the keyboard connector.
3. Connect the keyboard flex cable to its interface connector on the system board.
To aid with proper flex cable connection, a white locator line has been added near the end of the flex cable. Press the
cable into the connector until the white line disappears and hold it steady while you snap the flex cable connector down.
(The white line may reappear after the connector is closed; this should not indicate a problem with the connection.)
NOTICE: Position the keyboard flex cable so that it is not pinched when you replace the keyboard in the bottom case.
