I can't find any schematics for the motherboard, presumably as it is too new.

Does the laptop indicate any signs of life e.g. battery charging light when charger connected etc?

You may have to check for any obviously damaged components on the board near to where the short occurred. If you're not sure, post some close up images of the board back here in your question and hopefully someone may see something that you missed.

Here's how on ifixit 在已经存在的问题里加入图片

1 - I checked the battery connector on the motherboard with a multimeter. voltage was present (19-20 V). 2 - the connector on the red and white cable of the battery touched the connector and suddenly the laptop stopped working. The BGA control chip is not supplying any voltage to the battery connector. The motherboard is completely silent. I think there is something wrong with the BGA control chip.

no short circuits and other burns occurred on the motherboard. when connected to electricity, it shows that the charger is connected - the small colored lights in the place where the laptop power cord is connected do not light up. but the laptop doesn't work at all. There is no voltage on the battery connector.

The scheme can be obtained by contacting Samsung in Kareya.

What advice can you give in this situation? looking for burnt details on the motherboard. or BGA chip replacement.
