B Notes About Charging with Connection to a Computer
• The battery cannot be charged, nor can data be transferred, when the camera is connected to a
computer before the camera’s display language and date and time have been set (A24). If the
camera’s clock battery (A25) has been exhausted, the date and time must be reset before the
battery can be charged or images can be transferred with connection to a computer. In this case,
use the Charging AC Adapter EH-69P (A18) to charge the battery and then set the camera’s date
and time.
• If the camera is turned off, charging will also stop.
• If the computer enters sleep mode while charging, charging will stop and the camera may turn off.
• When disconnecting the camera from the computer, turn the camera off and then disconnect the
USB cable.
• About 4 hours are required to charge a fully exhausted battery. Charging time increases when
images are transferred while the battery is charging.
• When the camera is connected to a computer, an application installed on the computer, such as
Nikon Transfer 2, may start. If the camera was connected to the computer for the sole purpose of
charging the battery, exit the application.
• The camera turns off automatically if there is no communication with the computer for 30 minutes
after the battery has finished charging.
• Depending upon computer specifications, settings, and power supply and allocation, it may be
impossible to charge the battery using a computer connection while it is inserted into the camera.
C The Charge Lamp
The following chart explains charge lamp status when the camera is connected to a computer.

• The ambient temperature is not suited to charging. Charge the
battery indoors with an ambient temperature of 5°C to 35°C (41°F
to 95°F).
• The USB cable is not connected correctly, or the battery is faulty.
Make sure the USB cable is connected correctly and replace the
battery if necessary.
• The computer is in sleep mode and is not supplying power. Wake
up the computer.
• The battery cannot be charged because the computer cannot
supply power to the camera due to the computer’s settings or its
specifications.
