flashes green and goes out AC200P

Good afternoon!

The station was charging at night, sometimes the fan turned on, as I understand it - it was a little noisy. In the morning it showed a charge of 100% and I unplugged it from the outlet.

Three hours later, it turned on, the display lit up and went out.

The next time you turn it on, it flashes green and goes out.

What to do and why it happened?
