To replace the display assembly, the assembly must be removed from the system unit module. This is done by removing the keyboard assembly, disconnecting the display cable and display ground cable from the system unit module, removing the tilt feet and handle brackets, removing the rear clutch screws, and lifting off the display assembly. To service display components, do not remove the display assembly from the system unit module (unless the display enclosure or clutch replacement is required). Access display components (inverter board or latches) by removing the bezel secured with four screws on the front of the display. The display cable is a prefolded, flex cable that connects to the display inverter board with a low insertion force (LIF) connector. The other end of the display cable is exposed at the bottom of the display enclosure and connects to the system board with a zero insertion force (ZIF) slide connector. The display ground cable connects to the display shield on one end, and the other end clips to a LIF-type spring clip located above the serial port between the system board and system chassis. The display inverter board is aligned to the right of the display enclosure with pins. One end connects to the display cable; the other end connects to the backlight cable of the LCD panel.
Chapter 1.5 Docking Base The docking base includes the following replaceable parts: o Battery door o Feet o Handle
Chapter 1.6 Monitor Support Cover The monitor support cover is used with the docking base. The foot on the monitor support cover is the only replaceable part.
