3.0 Product Disassembly Process
3.1 List the basic steps that should typically be followed to remove components and materials
requiring selective treatment:
SYSTEM BOARD
1 To remove the access panel (see Figure 1 below):
a. Loosen the captive thumbscrew that secures the access panel to the computer chassis.
b. Slide the access panel back about 2.5 cm (1 inch), and then lift it off the unit.
2 Unplug all cables from the system board (see Figure 2 below).
3 To remove the heatsink (see Figure 3 & 4 below):
a. Disconnect the heatsink fan cable from the system board.
b. Loosen the two screws that secure the heatsink to the processor.
c. Twist the heatsink to break the bond between it and the processor.
d. Lift the heatsink from the processor.
4 To remove the processor (see Figure 5 below):
a. Rotate the socket handle to its fully open position.
b. Lift the processor from the system board.
5 To remove the system board (see Figures 6 & 7 below):
a. Remove the eight screws that secure the system board to the chassis.
b. Slide the system board toward the front of the computer until the rear I/O connectors
clear the chassis, and then lift the system board out of the chassis.
POWER SUPPLY PCA
1 To remove the power supply (see Figure 8 below):
a. Disconnect all power cables from all devices.
b. Remove the screws that connect the power supply to the chassis.
c. Slide the power supply toward the front of the computer, and then lift it out of the
computer.
2 Remove the cover from the power supply by removing the screws from the power supply
surface, and then lifting the cover off of the power supply (see Figure 9 below)
3 Unplug all cables and remove all screws inside of the power supply.
4 Cut the four cables (two each) connected to the Switch and the Inlet
(see Figure 10 below).

POWER SUPPLY PCA (
continued )
5 Remove the power supply PCA from the power supply (see Figure 11 below)
6 Cut the two capacitors (C4, C5) (see Figure 12 below) solder joint using dikes (see Figure
13 below), and then remove the capacitors.
BATTERY
1 Locate the battery and battery holder on the system board.
2 Depending on the type of battery holder on your system board, complete the following
instructions to replace the battery:
Type 1 Battery Holder (see Figure 14 below)
- Lift the battery out of the holder.
Type 2 Battery Holder (see Figure 15 below)
- To release the battery from the holder, squeeze the metal clamp that extends above one
edge of the battery. When the battery pops up, lift it out.
Type 3 Battery Holder (see Figure 16 below)
- To release the battery from the holder, press back the lever that extends above one edge
of the battery. When the battery pops up, lift it out.
