Question about Garmin nuvi 780 GPS
Possible bad battery---are you charging with the lighter plug in the vehicle or what? That plug it uses for the lighter will have a fuse inside it in most cases.........

with the garmin off, hold down the right bottom of the screen and turn the garmin on, it will then ask you if you want to perform a hard reset. Choose yes and that should fix your problem.

Hold your finger on the top left corner of the screen while turning it on. Release the power button when you see the Garmin logo pop up but keep your finger on the top left corner until the white calibration screen shows.
