Does anyone have a dell 9430, (LA-L461P) schematic and boardview diagram, i really appreciate your help.

I found the fault on the motherboard. It's the PU501 labeled (APAN 433), which powers the M2 slots.
I've searched all over the internet, but to no avail. It would be nice if someone could identify this component.

Thank You So Much, SMDFlea! 🙏
I was finally able to identify the mystery component labeled APAN 433. It turns out it's the NB679AGD, a synchronous buck converter. I had been stuck for days, and your post was the breakthrough I needed.

I really appreciate your help — you saved me (and probably my SSD too 😅).
Thanks again for being awesome!
