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 system board (see Figure 6):
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 10 screws that secure the system board to the chassis.
c. Slide the system board toward the front of the computer, and then lift the board up to remove it.
6. To remove the power supply:
a. Remove the four screws that secure the power supply to the chassis (see Figure 7).
b. Press the tab in front of the power supply that holds it in place (see Figure 8).
c. Slide the power supply toward the front of the computer, rotate toward the fan so the power supply clears the lip on
the top of the chassis, and then lift the power supply out of the chassis.
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 plastic clamp that secures the wires to the power supply cover.
b. Using a phillips screwdriver, remove the six screws that secure the cover to the power supply chassis - four screws
on top, two screws on the bottom (see Figures 9 & 10).
NOTE: You do not need to remove the screws from the fan guard or the power connector.
c. Slide the cover off the power supply.
d. Remove the two screws that secure the top PCA to the power supply (see Figure 11).
e. Using dikes, cut all cables connecting the PCA to the power supply.
f. Remove the four screws that secure the power supply PCA to the chassis (see Figure 12).
g. Remove the power supply PCA from the power supply chassis.
h. Cut the small PCA from the large power supply PCA (see Figure 13).
i. Cut 4 capacitors from the PCA, as shown in Figure 13.
POWER SUPPLY 2:
a. Using dikes, cut the plastic clamp that secures the wires to the power supply cover.
b. Using a phillips screwdriver, remove the four screws that secure the cover to the power supply chassis - two screws
on top, two screws on the bottom (see Figures 14 & 15).
NOTE: You do not need to remove the screws from the fan guard or the power connector.
c. Lift the cover off the power supply.
d. Using dikes, cut all cables connecting the PCA to the power supply.
e. From the outside, remove the four screws that secure the power supply PCA to the chassis (see Figue 16).
f. Remove the PCA from the power supply chassis as shown in Figure 17.
g. Cut 5 capacitors from the PCA, as shown in Figure 17.
POWER SUPPLY 3:
a. Using dikes, cut the plastic clamp that secures the wires to the power supply cover.
b. Using a phillips screwdriver, remove the four screws that secure the cover to the power supply chassis - two screws
on top, two screws on the bottom (see Figure 18 & 19).
NOTE: You do not need to remove the screws from the fan guard or the power connector.
c. Slide the cover off the power supply.
d. Remove the two screws that secure the top PCA to the power supply (see Figure 20).
e. Using dikes, cut all cables connecting the PCA to the power supply.
f. From the outside, remove the four screws that secure the power supply PCA to the chassis (see Figure 21).
g. Remove the power supply PCA from the power supply chassis.
h. Cut the small PCA from the large PCA (see Figure 22).
i. Cut 9 capacitors from the PCA, as shown in Figure 22.
3.2 Optional Graphic. If the disassembly process is complex, insert a graphic illustration below to identify the items
contained in the product that require selective treatment (with descriptions and arrows identifying locations).
