Moin, I replaced the charging socket on my laptop with the cable that leads to the mainboard, because the old one was broken and could not be used. Now I have the problem that the laptop no longer works and also no longer addresses because the battery is empty. The question is whether the mainboard is defective because there was a short spark in the old cable (I suspected a short circuit) and with the new one nothing works, but the voltage on the mainboard comes from the power supply.
Polarity reversed?
After a flight of sparks it can be assumed that the laptop has drifted into the eternal hunting grounds.
If I understand that correctly, is the charging contact on or in the housing on a separate board? Or do my thoughts go the wrong way
I have already watched it but in my view it is correct
You are probably right there.
It will probably have shot the charge controller.
That's right, the charging contact has its own board, which is then connected to the main board via cable.
There was a flying sparks in the cable, the circuit board looks perfectly
I believe you… PCBs are multi-layered and you can't see into the components with micro circuit.
Maybe you also used the wrong soldering iron, either GAS, ACCU or voltage-free (potential-free) it has to be… Not a snot from the hardware store for 8 euro
I swapped the board where the connector was on, since the board is inside
I'm not talking about the connection board, but the mainboard… It's hard to see a defect on the outside.
Oh well, then I think the mainboard is really defective
