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 NS-PCW4050/NS-PCW4050-C,
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.
