Maybe someone has a boardview or a schematic for this motherboard?
I need a verified kbc and bios dump. I'm thinking about trying to replace the KBC with a new one.

HP ENVY X360 15-EU0005NA 203037-2 does not turn on, something whistles on the board.
Hello, HP laptop model 15-EU0005NA. It does not turn on, 1 in 100 manages to turn it on then after a while it freezes/disappears/flashes, etc.
After removing the motherboard and connecting the board with RAM to the power supply, I noticed that at first all voltages start correctly and after a few seconds 3.3V on the PL4501 coil disappears and somewhere in this area something starts beeping on the board, sometimes after touching it with a finger in the area of PL4551 it stops beeping and 3.3V appears again.
Original HP 150W power supply, the diode in the power socket lights...

I only have the U2101 32MB chip on the board, there is no U2104 and it looks like it was never there....

The laptop does not respond to the power button, voltages of 3.3v and 5v are present. On the 3.3v switch it drops to 0 when pressed, charging the batteries.
After connecting the power supply, the battery charging LED lights up and the power LED flashes 3 times.
The U2104 chip is not on the board

The original upload looks damaged to me because it is very different from the ones I downloaded here....

I'm bumping the topic, would someone help me unpack a clean BIOS from the manufacturer's website?

The laptop with the original batch does not display the image and displays error 3.6 (Flash memory corruption).
I uploaded the batch from post #4 but it still does not display the image and this batch displays error 2.1 (Possible processor failure)....
