1 Securing clips (2) To reinstall a RIMM, perform the following steps: 1. Locate the plastic securing clips at each end of the socket (see Figure 26). 2. Press the clips outward until they snap open. 3. Press the RIMM straight into the slot running down the center of the socket until the securing tabs snap into place around the ends of the RIMM. 4. Replace the computer cover. 5. Reset the chassis intrusion detector. Figure 26. RIMM Installation 1 Securing clips (2) 2 Notches (2) 6.
1. Remove the computer cover. 2. Disconnect the cooling fan power cable from its system board connector. 3. Remove the metal retaining clip that secures the cooling fan/heat sink assembly to the microprocessor package by gently pushing down on the folded part of the retaining clip with a small screwdriver. The retaining clip hooks over the sides of the zero insertion force (ZIF) socket. 4. Remove the heat sink assembly from the microprocessor package.
NOTICE: Do not reuse the old heat sink assembly when you replace the microprocessor package. Using the old heat sink assembly can cause the microprocessor to overheat because there is not enough thermal compound between the old heat sink assembly and the microprocessor package. 9. Replace the heat sink assembly. a. Peel the release liner from the adhesive tape attached to the bottom of the new heat sink assembly. b. Place the heat sink assembly on top of the microprocessor package. c.
1 System board 2 Screw To remove the system board, perform the following steps: 1. Disconnect all cables from their connectors at the back of the computer. 2. Remove the drive shelf assembly. 3. Remove the expansion-card cage. 4. Remove the hard-disk drive/bracket. 5. Disconnect all cables from the system board. 6. Remove the screw that secures the system board to the bottom of the chassis (see Figure 31). 7. Slide the system board toward the front of the chassis until it stops. 8.
