Troubleshooting
If your new power supply is not working correctly, try the following:
- Make sure that the computer power cord is firmly plugged into the power cord connector on your computer.
- If you are using a surge protector, make sure that it is plugged in and turned on.
- Make sure that the wall outlet is supplying power. For example, plug a lamp into the outlet and turn it on.
- If you have the DX-400WPS, make sure that the red voltage switch (located on the back of the power supply) is set to the correct voltage setting. The setting for the United States is 115 V. The setting for Europe and other countries is 230 V.
