Acer AN515-55-57 LA-K861P

Looking for board schematic for an AN515-55-57
board writing is GH51M LA-K861P Rev: 1B

When given power, the unit has lights for RGB keyboard that light up but fans do not engage and unit doesnt post. I have isolated unit down to just the required pieces and still will not post.

Thanks in advance.

Hey thanks!

I started working through the power supply side of this board and am having a hard time locating the components listed in the schematic. It seems like only a few of the components actually have silkscreened identifiers on the board. Looking through the schematic, I do not see a componentry or location diagram, is that typically not available or is it housed in another document?

Not sure of the customs on this forum so I am just going to continue in this post. Digging through and testing using the provided information has led me to a lack of +VCC_CORE that is preventing startup. It looks like +Vcc_Core is supplied by D2/S1 of PQZ1 which is closed by D1 of PQZ1. Am I missing something?
