3.0 Product Disassembly Process
CMOS BATTERY
1 Remove the two screws that secure the cover to the chassis (see Figure 1 below).
2 Pull the chassis cover off the chassis.
3 Disconnect the speaker cable from the system board.
4 After locating the battery on the system board, pull back on the clip that holds the battery
in place, and then remove the battery (see Figure 2 below).
SYSTEM BOARD AND CAPACITOR
1 Remove the four screws that secure the system board to the chassis (see Figure 3 below).
2 Loosen the four screws that secure each heatsink (eight total heatsink screws)
(see Figure 3 below). You can either remove the heatsinks or leave them on the PCA.
3 Remove the two black screws, one on each side, near the back of the unit (see Figure 4
below). The screws hold the copper tubing in place. You can remove the copper tubing
now or when you remove the system board from the unit.
4 Lift up the rear of the PC, and then lift the PCA up and out of the chassis.
5 Using diagonal cutters, cut the one capacitor as shown in Figure 5 below.
