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. Pull up and hold open the latch on the top of the computer.
b. Slide the access panel back about 1.3 cm (0.5 inch), and then lift it off of the unit.
2 To remove the front bezel (see Figure 2 below):
a. Pull up on the three release tabs on the top of the bezel.
b. Pull the front bezel away from the chassis.
3 Rotate the drive cage to its full upright position (see Figure 3 below).
4 Unplug all cables from the system board (see Figure 4 below).
5 To remove the heatsink assembly (see Figures 5 & 6 below):
a. Loosen the two captive screws that secure the heatsink to the system board.
b. Twist the heatsink slightly to break the bond between it and the processor then, and
then lift the heatsink from the processor.
6 To remove the processor (see Figure 7 below):
a. Rotate the socket handle to its fully open position.
b. Lift the processor from the system board.
7 To remove the system board (see Figures 8 & 9 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 remove the system board from the chassis.
POWER SUPPLY PCA
1 Make sure the drive cage is rotated to its fully upright position, and then disconnect all
power cables from all devices.
2 To remove the power supply (see Figure 10 below):
a. Remove the three screws that connect the power supply to the chassis.
b. Slide the power supply forward about 0.95 cm (3/8 inch), lift it to clear the guides on the
floor of the chassis, and then pivot the top of the power supply to clear the top chassis lip.
3 Cut the tie-wrap (see Figure 11 below).

POWER SUPPLY PCA (
continued
)
4 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 12 below).
5 Cut the two cables that connect the Switch (see Figure 13 below).
6 Cut the two cables that connect the Inlet (Figure 14 below).
7 Remove the power supply PCA from the power supply (see Figure 15 below).
8 Cut the capacitors (C4, C5) solder joint (see Figure 16 below) using dikes (see Figure 17
below), and then remove the capacitors.
9 Cut the capacitor (C11) solder joint using dikes, and then remove the capacitor (see
Figure 18 below).
BATTERY
1 Locate the battery and battery holder on the system board.
2 Depending on the type of battery holder on the system board, complete the following
instructions to replace the battery:
Type 1 Battery Holder (see Figure 19 below)
- Lift the battery out of the holder.
Type 2 Battery Holder (see Figure 20 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.
