"There are several reasons why your camera's battery may not charge, and none of these will be affected by such a thing as a factory reset (if such a thing even exists on this camera).
The battery might be dead (worn or damaged)The camera's USB socket (which is also used for charging) might be worn or dodgyThe USB cord might be badThe charger might be bad.
You can do the following:
Check if the camera will charge with any other USB charger (for a phone or tablet, they are interchangeable)Check if the camera will charge from a computer's USB portCheck if the camera will charge using a different USB cord
If none of this works:
Take out the battery, clean its contacts with a pencil eraser and reinsert. Try if it will charge.Delicately wiggle the USB connector in the camera's USB port. If the camera charges (intermittently) the USB port may be dodgy or damaged. This is a common problem with micro-USB ports on many devices.Replace the battery with a new one or a spare if you have one."
