no power to Dell desktop

Kenny,

I’d suggest that you follow the steps mentioned below and check for issue resolution.

1. Switch off the computer.

2. Disconnect the power cable from the wall.

3. Disconnect all the peripherals from the tower

4. Press and hold down the power button for 15 seconds.

5. Then connect back all the peripherals and check if you are able to switch on the computer.

Also, please let us know if you find any Light indicators on the AC adapter and the system.

In addition, please revert to us with exact system model.

Replace your power cable to understand it's power cable fault or not.
