Keep pressure applied to the slider-spring assembly while unsnapping the 
latch to prevent the slider-spring assembly from coming loose from the 
case. If the slider-spring assembly does come loose from the case:
a. Carefully reinsert the spring onto the plunger on the slider, and reinstall 
the slider-spring assembly into the holding features on the inside of the 
case.
b. Ensure that the plunger is inserted in its respective hole, that the side 
of the slider with the two bumps is facing the rear of the case, and that 
the surface with the wear ribs is facing the bottom of the case (see Fig-
ure 4-29).

The system board’s BIOS chip contains the system service tag number, which 
is also visible on a bar-code label on the bottom of the computer. The replace-
ment kit for the system board assembly includes a diskette that provides a 
utility for transferring the service tag number to the replacement system board 
assembly.

Be sure and transfer the memory module(s) to the replacement system board 
assembly. If you are replacing the thermal cooling assembly with a new one, 
remove any lining present on the thermal pad before installing the new thermal 
cooling assembly.
After replacing the system board assembly, be sure to enter the system’s ser-
vice tag number into the BIOS of the replacement system board assembly. 
Insert the diskette that accompanied the replacement system board assembly 
into the diskette drive, and turn on the computer. Follow the instructions on the 
display screen.

NOTE: When replacing the exhaust fan, orient the fan such that the fan label 
faces outward and the power cable is at the upper right corner of the fan 
(when viewed from the back of the computer). (This will prevent the fan wires 
from being pinched when you reassemble the computer.) Make sure that the 
wires are routed below the upper EMI shield.

b. Remove the remnants of the foam pad from the system board 
assembly.
