How to test ncp81382

[khelane]

Hello
please help me. How can I check if this IC ncp81382 is healthy or not?

The zbook 15 G3 had a problem with the CPU controller IC and the 5V part was connected, after replacing it it was fixed, but now I still don't have the CPU voltage output.

What is the resistance to ground of the cpu power rails? No power to the board during resistance checks.

PL47&PL49 : 3.1 Ohm
PL48&PL50 : 4.1 Ohm

The device would not turn on. After checking the two type c controllers, the device was burned, as well as the two USB ESD protection diodes. I removed all four, the problem of connecting the voltage input 19 was solved, but I had a connection in +5VDS. After checking the processor controller IC with the number NCP 81205. There was a connection on its pin 16. I removed this IC, the problem was solved, and then I replaced the IC. Now the device starts and the voltages are established except for the processor voltages. Separate graphics voltage is also generated.

What is the voltage of the pwm pin?

Problem solved
Resistors PR 174 and PR 193 were replaced and the problem was solved.
Now the VCORE voltage is established and the device shows an image after the BIOS program, but the inductors 48 and 50 do not have voltage.
Now the device shows an image but the SSD and hard drive are not recognized and I am currently looking for the BIOS for the device to see if it is from the BIOS.
This is the BIOS of the device itself

Can you fix the BIOS for me?

tnx

Post the same request inside the dedicated bios forum. See above. Someone there will be able to help.

I requested the BIOS.
I got a BIOS that came with the image but gave a warning.
I accidentally faked the BIOS of the device itself and with that image came the image but it still gives two warnings.
I set the factory settings in the BIOS and restarted it but
it does not recognize the SSD and WLAN.
I also updated the BIOS to the latest version but these two components are still not recognized. While I can install Windows with the
HDD
SSD AND WLAN
tested and works.
By the way, I am still waiting for the BIOS that I requested in a separate thread.
