HP computer won't turn on after getting wet.

Hello, I need help diagnosing and repairing the problem with my HP laptop.

While it was powered on, I spilled a glass of water on it and it immediately turned off. I quickly removed the battery and the power cord. I let it dry for several days and now when I try to turn it back on, nothing happens, no LED indicating that the charger is plugged in, and of course, no fan starts up. From now on, I don't know what to do. I've disassembled the motherboard:

In the photos, I have removed the RAM stick, the m.2 nvme SSD, the wifi card, the speakers, and the cooling fan.

I have a multimeter, a soldering iron, some old faulty motherboards for parts, and I can buy a hot air soldering station if needed.

So my question is: how to diagnose what the problem is and how to fix it if possible?

Here are the references for the laptop: hp 14-dk1022nf

And the motherboard reference: 14-fp5-6l-gddr5x2

    Hello

    It's pointless to waste your time if water has touched the motherboard while powered on, it's dead.

    Look to buy an identical motherboard on AliExpress, that's the only economically interesting thing to do.

    Yes, I'm afraid the processor took a hit tonight. But a motherboard costs at least €150, so it's not worth buying a new one.

    I'm staying optimistic, and I would really like to test the mosfets and the 3v and 5v chip. Because I should note that I can still measure a voltage of 3v and 5v on 2 coils. But I can't locate the mosfets and the 3v and 5v chip on the motherboard.
