nvm, just figured that type somewhat under microscope. It's LV5116AGQW

Mod can lock this thread, solved. Thanks anyway.

Thanks,the info that PU4 is a LV5116AGQW . The thread will stay open,someone will post the schematic if and when it becomes available

Can somebody perhaps provide a schematic for this motherboard? I am working on a repair but sadly could not find the schematic for download. The CPU supply DCDC converters seem to be shorted on my board but without a schematic it's a guessing game what exactly is causing this.

I don't have it. But I have the sister to this design. Motherboard looks exact the same too in pics. if it helps at least.

This might be boardview

what application do you use to open the FZ file, it does not open with boardviewer or flexbv. thank.

Oh sorry, just rename it to GE4B0.fz

Sorry again, it didn't work to rename the file Ge4B0.RAR to Ge4B0.FZ... can you please confirm the file on your side or upload it again, thanks again.

thank you Lisa Su, i can open the file with TeboView...

Sorry, again. I meant to write "just rename it to GE4B0.tvw" in my previous post.

UnRAR GE4B0.rar > GE4B0.fz > GE4B0.tvw

thank you Lisa Su, i can open the file with TeboView...

Once renamed, you can also open it with BoardViewer 2.0.1.9

Hey so, I'm pretty new to this so forgive my ignorance here. I got the file opened in that BoardViewer software mentioned by Lisa Su and it is really cool!

I was just wondering if there was a way to view the component values, and/or if the part info was to be trusted. I was randomly looking at some of the resistors and their info said something like, "1/16W_0_5%_0402". Does this just mean the particular resistor I'm looking at is 0 ohms, or is this some kind of error?

Any input would be appreciated! I'm trying to undo some damage caused by a repair shop and I will probably need to replace some 0402 passives that are mysteriously absent...

yes,one sixteenth of a watt , 0 ohms 5% tolerance , 0402 size.

Awesome thanks! Does anyone know the minimum hardware I need to connect(fan, keyboard, etc) in order to see if it is receiving power via the USB C input?

Right now my plan is to replace the port and all the 0201 components near it because I suspect the previous repair attempt may have dislodged some, as there seem to be quite a few missing components. From there I can start troubleshooting component failures deeper in.

Actually, is it typical for boards to have a few unpopulated components? Does this sound like a dumb approach?
