Nikon Issues Overheating Warning for Coolpix L23
"In some rare cases," says the advisory, "when the batteries are inserted, or the AC Adapter EH-65A is connected, even with the camera turned off, excessive heat is generated in the top portion of the camera, which sometimes causes the top cover to become deformed."
If you have a white circle on your tripod socket, then you don't need to be concerned - your camera has already been inspected and it's just dandy. If not, or if you just want to make sure, you can contact Nikon at 1-800-Nikon US (1-800-645-6687) with your serial number handy.
