How to detect the capacitance of the computer motherboard

The method of judging whether the capacitor on the motherboard is good or bad:

1. Discharge the capacitor, then connect the negative pole of the capacitor with an electric pen red and a black test pen.

2. Determine the quality of the capacitor according to the deflection of the hands:

a. If the hands are quickly swung to the right and then slowly retracted to the left, the capacitor is generally good.

b. If the needle does not turn after swinging, the capacitor has broken down.

c. If the needle is gradually returned to a certain position after the needle is swung, the capacitor has leaked.

d. If the hands are not placed, the capacitor electrolyte has dried up and lost capacity.
