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....

This is just a dump for kbc and I need the main bios....Leave a comment:

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....Leave a comment:

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)....Leave a comment:
