    MSI ms-15ck1 motherboard died while unplugin internal display connector

    Hello, could you help me ?
    I think I killed my MSI ms-15ck1 motherboard while unplugin internal display connector i tried to replace , without previously unplugin battery connector because now i cannot turn the laptop (msi delta 15) on . Not light turning on at all. Can it be fixed? What component should I check *fuse , transistor...?) And where to check in the mother board ? . Thank you for your help!

    Do you have a voltage at the eDP connector? It's likely that if the fuse is blown, then the mainboard still can start.

      Thank you for your answer.
      I can find some voltages around the eDP connector in the motherboard side but i dont know where to check exactly ? Attached to my post i took a photo of the connector in the motherboard side. Could you help where/ what to check? I can add that the laptop do not start a all when trying to turn it on. No fan, no charger light.. thank you !

        It looks like that there is a hole in the chip next to U37

          Thank you diamon FriedFred i checked and i did not find a hole in a chip next U37. But I found this grey smd next to the edp connector. It seems to be shorted? when testing with multimeter and puting the probes at both ends . could that be a shorted capacitor or is it something else normal. Thanks you for your help!

              This component is a ferrite bead / coil that is acting like an EMI noise filter. It is present to clean up certain frequency noise. The measurement across the contacts will read a ~0 ohms which is normal unless the part is damaged.

                  Suggest to start with the DCin power connector. Review the voltage to ground on each pin of the power adapter. Do you have the expected ~19v at the DCin power jack?

                  Then continue to locate the 2 x DCin mosfets between this connector and the battery charger IC. Which battery charger IC is onboard? Share the topside markings. This may be the popular BQ series by Texas Instruments. From that knowledge, we can review reference schematics to get a feel for what may be onboard your logic board.

                  At this time, do not believe there is a schematic for your board.
