Medion Erazer X15803 - blown resistors

[gurj1979]

Hi folks.
I have a Medion Erazer X15803 with board number MBPGK7CP7C-SN12 (no schematics on the internet) which uses Monolith Buck Converter MP2949A for CPU power. It has 2 burnt out resistors.
R332 is missing the solder tabs so I cant even get any reading from it.
R330 shows 5ohm.1

What are the values of these 2 resistors ?
Image attached.

Thanks.

I guess upper resistor is related to VIN_SEN? not sure about the other one. Share the value of the resistor to the left of the upper missing resistor and clarify to which pin the second resistor has to be connected. Should be possible to work with schematics from another board here, at least till some degree.

I checked with another Monolith buck conv but for GPU and tried it. Different model chip, but I found a pattern of circuit. It uses 2MOhm in that circuit. I could only find 1Mohm from my stash of battered boards. So 20v goes in, and 2v comes out when used with 1Mohm.

CPU just reballed, so I'll check it out in a bit.

Not sure whether it is a good idea to place a resistor there with half of the resistance. From my research I've also seen 2m and 133k for this voltage divider. However, you decide.

CPU back on. Missing resistors in place. Still no VCORE
