Caution: Be careful not to touch the capacitor wires as you work. If possible, use a capacitor discharge probe to safely rid the capacitors of dangerous charges.

Orient the base of the processor so that the power cord is facing you.

Locate the capacitor that you need to replace. The capacitor looks like a black cylindrical battery.

There are two capacitors in the device, but these steps refer to replacing the leftmost capacitor.

Slide the plastic covering off of the white wire connection on the top of the capacitor by pulling gently.
