Need help identifying resistor on Asus FA507RC DA0NJNMBAD0 schematic

[dutchgaucho]

Hi colleagues,

Looking for a schematic DA0NJNMBAD0 or the MP2845A 6-phase PWM controller.

Working here on a DA0NJNMBAD0 rev D motherboard (Asus FA507RC) with liquid damage. Board has some tiny corrosion around the MP2845A controller and one resistor is missing. I need to know the value of the resistor, but no schematics are available. Not even for the MP chip or anything similar (this is a 6 phase PWM controller).

On one side of the pad 20V is present. The other side connects to a cap and to pin 16 of the MP2845A. Resistor seems too small for VCC input so it's probably some feedback line or resistor for sensing but I'm not sure.
Does anyone have a clue?

Thanks a lot!

Nobody? There seems to be a datasheet on ******** but I don't have an account there. If somebody does have access to their website, I'd be very grateful! \

Hello everyone, I am working on a liquid damaged Asus FA507RC in 2024 and there still isn't schematic or boardview unfortunately. This board has got quite a few components missing and on attempt to power via bench power supply only draws 160mA ...
there is no voltage present even on the battery charging terminals. The areas that are missing components seems to be in the area of the EC controller so I am guessing it is related. May i kindly ask for help to identify the missing components in the areas circled marked in the pictures?

Pictures attached are the same area just different levels of zooming in. Or is there a way to infer from existing BV of similar motherboards the missing components?

Thank you all in advance.

guyandpit I have not been able to find any schematic or BV related to FA507R series, closest i have is BV for DA0NJSMBAD0. I think you can find adequate information from the older FA506 series in which there are quite a number schematics available. If you like PM for the NJS boardview and I would really appreciate if you can help me by taking a picture of the back view of your board as i would like to see if the missing components on mine match up with your board. perhaps we can help each other.?

hi sorry late reply hope you still need this see backview of the motherboard

Hello, could some one help me with one value of the same board DANJNMB1AA0 i need the value of one cap and one resistor, thanks!

Colleague, were you able to get the schematic diagram for the ASUS TUF A15 FA507RE with the motherboard DA0NJNMBAD0?
