A Nikon Coolpix camera may be charged either by using the USB port to connect the camera to a computer, or by using the charging adapter. In the event the USB port does not work, using the charging adapter is the back-up procedure.
Before attempting to charge the camera battery, it is important to make sure the battery door is closed and to follow the order of connections correctly if using the charging adapter, since either of these conditions will prevent the battery from recharging.
The USB can simply be connected to a computer, which should indicate immediately if the battery is charging. Using the charging adapter in the correct way should auto-start the charging process.
Step 1: Connect the adapter
Plug the USB into the adapter. Then, plug the adapter into an electrical outlet.
Step 2: Connect the camera
Connect the other end of the USB cable to the camera, first making sure the camera is turned off.
Step 3: Verify the charge
Check to make sure that the green LED begins to blink to indicate that charging has commenced. The light will turn off when the battery is fully charged. If the LED does not turn on, try turning on the camera to see if that starts the charging process.
There are some models of Nikon Coolpix cameras with known battery charging issues. Users should consult the Nikon website in the event of any problems to check for firmware updates that may address the issue.
