Applicable Products and Categories of This Article

The camera may become unresponsive or fail to turn on after the firmware is updated. This may be due to a low battery or an incomplete firmware installation. Follow these steps to address the issue:

1. Make sure the battery is fully charged. If you have the optional AC power adapter, connect it to the camera and a working electrical outlet.

**Note:** Batteries discharge faster when used in cold weather conditions.

2. Check if the USB cable is working properly.
3. Perform a manual reset on the camera.

1. Remove the battery.
   2. Set the power switch to ON.
   3. Press and hold the shutter button for 30 seconds.
   4. Set the power switch to OFF.
   5. Insert the battery back.
   6. Set the power switch to ON to see if the camera will turn on.

4. If the camera won't turn on after the manual reset, run the firmware again.
5. If necessary, use a different computer.

If the issue still occurs, repair may be required.  [Go to Product Repair.](https://us.esupport.sony.com/support/s/service?language=en_US)
