a. Loosen the microprocessor socket cam lock screw. The location of the screw and the rotation direction may vary with the socket manufacturer;
look for small icons indicating open and locked positions.
b. Use the microprocessor extraction tool to remove the microprocessor module.
Replacing the Microprocessor Module
1. Align the pin-1 triangle on the microprocessor toward the pin-1 triangle in the connector, insert the microprocessor into the socket, and move it around
slightly until you feel it settle into the socket.
When the microprocessor module is correctly seated, all four corners are aligned to the same height. If one or more corners of the module are higher
than the others, the module is not seated correctly.
2. Tighten the cam lock screw.
3. Replace the microprocessor thermal cooling assembly.
4. While pressing lightly down on the center of the retaining clip, insert a pry stick into the latch mechanism and pivot the top of the pry stick away from
the clip to close the latch.
NOTICE: After replacing the microprocessor module, update the BIOS using a flash BIOS update program floppy disk or CD that came with the
replacement microprocessor.
NOTICE: If the computer is running Microsoft®Windows®Millennium Edition (Me), you need to download the operating system update utility for
Windows Me from http://support.dell.com and install it before you upgrade the BIOS.
