Removing and Replacing Parts : Dell Inspiron 8100
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.
NOTICE: Proper seating of the microprocessor module does not require force.
NOTICE: A microprocessor module that is not properly seated can result in an
intermittent connection and subsequent failures.
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.
NOTICE: Hold the microprocessor down while turning the cam lock screw to
prevent intermittent contact between the cam lock screw and microprocessor.
2. Tighten the cam lock screw.
NOTICE: Do not over or under tighten the screw. Tighten it until the screw
indicator points to the "closed" or "locked" indicator on the socket.
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.
