Follow the troubleshooting steps below. Expand the sections below to learn how to perform each troubleshooting step to identify the cause and resolve the power issue on a Dell desktop or all-in-one.
Most often, restarting the computer resolved many issues. The residual power in the computer may cause the laptop not to turn on. Follow the steps below to drain the residual power.
If this did not resolve the issue, go to the next step.
The power cable, AC adapter cable, and power cables may get frayed or cut, and wires may become exposed at either end of the cables. This may be due to the way the cable is wrapped around the AC adapter, or if the cable is subject to undue stress. If the damage is severe enough to expose wires, you should discontinue using the power cable or AC adapter. To check the power cable, AC adapter, cables, and the power port on the desktop or all-in-one for any damages:
If you notice a damage, contact Dell Technical Support for repair options. If you do not find any damage, go to the next step.
If the power cable and the wall outlet are working correctly and the computer is not able to turn on, go to the next step.
Reseat the AC adapter by following these steps:
If the AC adapter LED indicator is on, go to the next step. If the AC adapter LED indicator is off or turns off when it is connected to the computer, contact Dell Technical Support for repair options.
It is important to verify that the voltage selection turn on the power supply unit is set to the correct voltage based on your current location. The power supply unit (PSU) of certain Dell desktops allow you to change the voltage from 110 V to 220 V depending on your current location.
For example, the standard voltage that is supported in the United States is 110 V and 230 V to 240 V in the United Kingdom. Ensure that the toggle turn on the power supply unit (PSU) is set to either 110 V or 220 V based on your current location.
If this did not resolve the issue or if there is no voltage selector toggle switch, go to the next step.
Dell Inspiron, XPS, OptiPlex, Precision, and Vostro desktop computers include a power supply with an integrated self-test (BIST) feature that helps diagnose the health of the power supply unit. The LED indicator on the PSU helps identify if the power issue is caused by the power supply unit.
If this did not resolve the issue, contact Dell Technical Support for repair options.
