    • Once you have unclipped the power cable, use a multimeter (left) to test if the cable is still functional.

    • Turn the dial on the multimeter to continuity test mode.

    • Make sure the positive lead is plugged into the voltmeter/ohmeter outlet.

    • Use one multimeter lead to touch one of the prongs on the AC side of power cable. Use the other lead to touch one end of the clip side of the power cable.

    • The multimeter will show numbers if there is a good electrical connection. If it does not show any numbers the first time, try using the lead to touch the other prong.

    • Repeat the above directions with the other prong and clip side of the power cable.

    • If the multimeter does not show numbers during any of the connections, your power cable is dead and you will need to replace it.

    • If you found that the power cable has a good electrical connection, you will have to test that the cable has not shorted out.

    • To do this, touch each prong on the AC side of the power cable. If numbers show on the screen, your power cable is bad and must be replaced.

    • If your power cable is bad, do not replug the cable into the AC outlet.

    • If the cable works, the problem is with the motherboard.
