3.0 Product Disassembly Process
3.1 List the basic steps that should typically be followed to remove components and materials requiring selective treatment:
1. To remove the access panel (see Figure 1):
a. Remove the two screws that secure the access panel to the computer chassis (1).
b. Slide the access panel back about 6 mm (1/4 inch), then rotate the top of the panel away from the chassis (pivot on
the bottom). and then lift it off the unit (2).
2. Remove or cut all expansion cards, cables, and any other devices from the system board.
3. To remove the system board (see Figure 2):
a. Remove the heatsink from the system board by loosening the four captive screws that secure the heatsink to the
system board, and then lifting the heatsink from the system board.
b. Remove the six screws that secure the system board to the chassis (1).
c. Slide the system board toward the front of the chassis, and then remove it (2).
4. To remove the battery:
Locate the battery and battery holder on the system board. Depending on the type of battery holder on the system
board, complete the following instructions to remove the battery.
TYPE 1 BATTERY HOLDER (see Figure 3):
Lift the battery out of the holder.
TYPE 2 BATTERY HOLDER (see Figure 4):
To release the battery from its 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 5):
Pull back on the clip that holds the battery in place, and then remove the battery.
5. To remove the power supply (see Figure 6):
a. Remove the four screws that secure the power supply to the chassis (1).
b. Slide the power supply toward the front of the computer, and then lift it out of the computer.
6. HP uses three different power supply vendors. See the instructions below to disassemble and remove required power
supply components:
POWER SUPPLY 1:
a. Using dikes, cut the two plastic cable clamps that secures the cables to the power supply cover (see Figure 7).
b. Using a phillips screwdriver, remove the five screws that secure the cover to the power supply chassis - three
screws on top, two screws on the bottom (see Figures 7 & 8).
NOTE: You do not need to remove the screws from the fan guard or the power connector.
c. Pull the cover toward the back of the power supply to remove it.
d. Using dikes, cut all cables connected to the PCA in the power supply.
e. Turn the power supply upside down, and then remove the four screws that secure the power supply PCA to the
chassis (see Figure 9).
f. Remove the power supply PCA from the power supply chassis.
g. Cut 8 capacitors from the PCA, as shown in Figure 10.
POWER SUPPLY 2:
a. Using dikes, cut the two plastic cable clamps that secures the cables to the power supply cover (see Figure 11).
b. Using a phillips screwdriver, remove the seven screws that secure the cover to the power supply chassis - four
screws on top, one screws on one side, two screws on the other side (see Figures 11 & 12).
NOTE: You do not need to remove the screws from the fan guard or the power connector.
c. Pull the cover from the power supply.
d. Using dikes, cut all cables connected to the PCA in the power supply.
e. Remove the four screws that secure the power supply PCA to the chassis (see Figure 13).
f. Remove the power supply PCA from the power supply chassis.
