Change to a new power supply may solve the earlier crash problem, but the problem we facing now may caused by the bios missing or the power management damaged.
So I think you can try to re-flash the bios follow the way above.

Hi, you said that the red light blinks when the power button pressed. So what is the status of the Red light before you press the power button?

Actually the LattePanda need 5V and at least 2A current. Please make sure the charge can provide enough current. Maybe the reason of the board crash down is the low current.
And now if the red led blinks all the time ,there are two most possible reason of it.
(1) The bios documents was missing , because of the abnormal crash down.
And you can try the solution below to fix the problem.

(2) The power management is damaged by the long time low supply. And what a shame there is no good way to fix it.

The red light shines indistinctly before you press the power button.
I have just tried to power up a 5V 2.5 amp ; charger, but the situation hasn't changed.

I powered up and booted up 5 V2 A charger.
The power went out while I was trying to move the file. This situation happened after several iterations of the procedure.
