Chuwi Lapbook Pro power supply problem

Due to a faulty charging cable, the power supply logic board, which supplies power to the laptop and the batteries, broke down. Because, the laptop was running till there was charge in the batteries. But later when I connected a proper charger, it wont light up anything in the laptop.
I have also raised a ticket on Chuwi’s official page. But received no response (it is more than 4 months now). I am also unable to get any spares online or from local vendors.
Please help…

The problem is not with the charging cable, but with the power supply logic board which distributes power to the laptop and the battery to charge (that is what the repair guy said). I need either a spare motherboard for the Chuwi lapbook pro, or a power supply card. What I understood.

Very strange conclusion, there is no point in replacing the power supply board, it is much cheaper to buy a new power supply. If you need the board for the laptop itself, you can probably only buy it from
