Replacing the Microprocessor Module
NOTICE: If you received a flash BIOS update program diskette or CD with the
replacement microprocessor, you must update the BIOS after replacing the
microprocessor module. For instructions on updating or reflashing the BIOS, see
the Dell Portable Computer BIOS Update Guide.
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.
