This was a funny one.
After taking some time to inspect carefully the SMC area, I noticed a blurry stain under it on the 4th solder ball zone, the PM_PWRBTN_L contact point!
It was hard to check under it as the angle is not the best, but there it was.
Some flux, a good reflow . and...
J1800 area is clean, the board is as new
R1450 is OK.
I guess only thing pulling down this signal is the SMC or U0500 right?
Diode mode at PM_PWRBTN_L 0.52

All the power rails read OK for this stage, and I'm using a 820-00239 schematic and BV.
This comes out from U0500 and I've measured...
