Service Issues; Palm Rest Removal; System Board Replacement - Dell LATITUDE D620 User Manual

Dell - Latitude™ D620 - Printer-Friendly Format
You need to address the following issues when replacing parts on the Latitude™ D620.
The palm rest on this system needs to be removed in a certain manner. Follow these steps:
1. Remove all parts necessary to access the palm rest.
2. Remove the nine securing screws from the bottom section of the system.
3. Remove the three palm rest screws from the upper section of the system.
4. Disconnect the cable connector attached to the system board located on the left side of the system.
5. Starting with the back of the palm rest (located near the LCD mounts), separate the palm rest from the base of the
system, and work it loose along the sides towards the front.
WARNING:
You must start removing the palm rest from the back. Failure to do so will damage the connector hooks located along
the front edge of the base plastics.
6. Once the back and sides of the palm rest are free, slide it forward to release it from the securing hooks located along
the front edge of the base plastics.
7. Remove the palm rest from the system.
The system board removal is straightforward.
However, replacing it correctly involves lining up
the wireless sniffer switch correctly, or the board
does not seat properly in the system.
When you reseat the system board, the wireless
switch must line up with the plastics as shown to
the right. If it is not lined up correctly, the board
does not seat down fully and hangs over the right
edge of the bottom plastics. At no point should
you force the board into place; this will damage
the plastics, the switch, or worse.
The easiest method of aligning the switch with the
plastics is to have both the interior switch on the
system board as well as the exterior switch on the
outer plastics in the "off" position, all the way
towards the back of the unit (closest to the LCD).
