Dell Latitude D620 ATG - Manual (Page 10)

Installing the Processor
1. Align the pin-1 corner of the processor so that it points to the triangle on the system board, and insert the processor into the ZIF socket.
When the processor is correctly seated, all four corners are aligned at the same height. If one or more corners of the processor are higher than the
others, the processor is not seated correctly.
2. Tighten the ZIF socket by turning the cam screw clockwise to secure the processor to the system board.
3. Peel the backing off the thermal cooling pad and adhere the pad to the portion of the thermal-cooling assembly that covers the processor.
4. Replace the processor thermal-cooling assembly (see Processor Thermal-Cooling Assembly ).
5. Replace the palm rest (see Palm Rest ).
6. Replace the keyboard (see Keyboard ).
7. Replace the media bay device (see Media Bay Devices ).
8. Replace the hinge cover (see Hinge Cover ).
9. Replace the battery.
10. Update the BIOS using a flash BIOS-update program CD. See Flashing the BIOS .

NOTICE: Ensure that the cam lock is in the fully open position before seating the processor. Seating the processor properly in the ZIF socket does not
require force.
NOTICE: A processor that is not properly seated can result in an intermittent connection or permanent damage to the processor and ZIF socket.
NOTICE: To prevent intermittent contact between the ZIF-socket cam screw and the processor when removing or replacing the processor, press to
apply slight pressure to the center of the processor while turning the cam screw.
NOTE: Ensure that you reconnect the coin-cell battery (see Coin-Cell Battery ) before you replace the keyboard.
