I haven't turned it on in a while, but no luck, and when I connect it to the charger, the red light energizes for a moment and then immediately shuts off.
When I looked at the current with the USB ammeter, 5V, 0.14A flowed for a moment, then the energizing lamp shone, and from there it was 0A and could not be charged.
The only thing I can think of is that it did not start up for almost a month, and there is no external damage.
Is there any solution to this problem?
