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 BI\
OS, 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. 
1.  Align the pin-1 triangle on the microprocessor toward the pin-1 tria\
ngle in the  socket, insert the microprocessor into the socket, and move it around sl\
ightly 
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.
