Dell Vostro 2520 (DV15 MLK MB) - what resistor R2941? diagram?

Hello,

I have a laptop as after flooding..
Unfortunately, the pads corroded so much that one resistor fell off.
I can't find a schematic anywhere.. Does anyone have this?
Or at least, if someone could tell me the resistance of this element, I would be very grateful.

It's about R2941 with the U2901 chip.





Plate:
DV15 MLK MB
11280-1
MXRD2 Rev:A00



Thanks in advance for your help.

U2901 designation?
Post a macro photo of its surroundings.
Album cast?
Is there a 48...... style mark on the disc?

Sorry.. I actually did not show off the above photo.
I put the plate designation as well as the place where the resistor is missing.

This is the Wistron DV15 platform on KBC NUVOTON NPCE885PA0DX
From the Polish forum Link_Elvikom

It's probably a sound chip from Cirrus A213DC?/*the name is hard to see link
* but the Cirrus company uses designations according to code e.g. CS 5333 (Cirrus)

Typically Dell used to have a series codec Link_ 92HD87B1X5NDGXTBX
Then helpful:
- SM from Quanta R53 and find the diagram on page xx under U35 (92HD87)
- meter and "on ohms find connections with the answer pin.u35"


This was done on Wistron Enrico Caruso DV15 HR MB 10316-1. Rev: A00

there were several revs in this DV15 series. sometimes differing in circuits in the audio path, KBC, chipset, in DC-DC converters, FAN control _no data and SM ,
* different numbering and descriptions of items elements per MB different rev.
- it ver. mainly for the US market

your model is on KBC NPCE885 and HM75 chipset (slj8f) under i3 (sandy bridge)

Take a look, for example, at the solutions from ENRICO's DV14

Hello,

Thanks for your answer, but I still can't solve it.

I found a sticker that might come in handy.

There you have a system in a 36QFN housing (i.e. 4x 9 pin)
Reading the brochure from the 2012 CirrusLogic company it turns out to be a CS42L55 chip

*unless it's something from early production

read the datasheet, compare by pins
- comes out of the photo. that the resistor is R2941 connected to pin.25 (A2INB analog signal input)
