adapter. Plug the power cord into a power outlet, surge protector, or power strip.

•
If you are using a power strip, make sure the power strip is turned on. Or, try
plugging the product directly into a power outlet.
•
Test the power outlet to make sure it is working. Plug in an appliance that you
know works, and see if the appliance has power. If not, then there might be a
problem with the power outlet.
•
If you plugged the product into a switched outlet, make sure the outlet is switched
on. If it is switched on but still does not work, then there might be a problem with
the power outlet.
Cause: There was a problem with the power cord or the power supply.
