5.5.15 Removing and Replacing the DAB
Board
To remove the DAB Board, refer to Figure 5-18 and perform the following
procedure:
1. Turn off the computer, remove the battery packs and disconnect the
ac power adapter (if it is attached).
2. Remove the Display Bezel as described in paragraph 5.5.14.
c Caution: If the notebook is powered up with the LCD bezel removed,
you can be exposed to high voltages which could result in shock and
equipment damage. Ensure that the batteries and AC adapter are re-
moved from the notebook when working on the LCD/Display assembly.
3. Peel back the protective insulator from the DAB Board.
4. Remove the two screws that secure the DAB board to the cover.
Carefully disconnect all cables that mate with the DAB Board.
n
Note: The display cable connects on the bottom side of the board with a ZIF
connector.
5. Remove the DAB Board protective insulator from the cover.
6. To install a replacement DAB Board, reverse steps 1 through 4 above.
Carefully insert the video cable (ribbon cable) into the ZIF connector
on the DAB Board (unlock the connector, insert the cable and then
lock the connector) and insert the small connector on Connector J2
on the Power Inverter Board. Ensure that the grounding strap is
placed underneath the right side of the DAB board and tightly
secured by the right side screw. Tighten down the DAB Board, secure
the DAB Board insulator to the top of the board, and replace the LCD
plastic bezel.
