Microprocessor Module: Dell Inspiron 1100, 5100, and 5150 Service Manual
NOTICE: Ensure that the cam lock is in the fully open position before seating
the microprocessor module. Seating the microprocessor module properly in the
ZIF socket does not require force.
NOTICE: A microprocessor module that is not properly seated can result in an
intermittent connection or permanent damage to the microprocessor and ZIF
socket.
1. Align the pin-1 corner of the microprocessor module so that it points to the
triangle on the system board, and insert the microprocessor module into the ZIF
socket.
When the microprocessor module is correctly seated, all four corners are aligned
at the same height. If one or more corners of the module are higher than the
others, the module is not seated correctly.
NOTICE: Hold the microprocessor down while turning the cam screw to prevent
intermittent contact between the cam screw and microprocessor.
2. Tighten the ZIF socket by turning the cam screw clockwise to secure the
microprocessor module to the system board.
3. Wipe the thermal grease off of the microprocessor thermal-cooling assembly
with a clean paper towel.
4. Squeeze all of the contents of the thermal grease packet (provided with the kit)
on to the microprocessor thermal-cooling assembly.
5. Replace the microprocessor thermal-cooling assembly.
6. For the Inspiron 5150, replace the palm rest and then replace the display panel.
7. Replace the EMI shield.
8. Replace the keyboard.
9. Update the BIOS using a flash BIOS update program CD.
