Hello everyone,

I’m looking for the schematic and boardview files specifically for the AMD version of the HP Omen 16 laptop, model xf0006AX, equipped with the Ryzen 7 7840H CPU.

Most of the files I’ve found are for Intel CPU versions, and I need the exact files for this AMD Ryzen 7 7840H model to assist with repair and troubleshooting.

If anyone has access to these files or can kindly share the boardview and schematic for this particular AMD version, I would really appreciate your support.

Thank you very much in advance!

Hi guys, I'm working on a MSI Ventus RTX 4080 16G. The GPU has 12v, 5v, however what I assume is the 1.8v rail has 1.1v and what I assume to be PEX is 0v. As you may have guessed already there is no Vmem and no Vcore.

I have looked around in related forum posts for a schematic so Much appreciated if anyone can share a Broadview schematic.

Thanks.

Hello,

I have re-soldered the loose pins on the RAM slot which is a common fault on these models..

It charges and turns on the power LED but is missing several voltages like RAM and CPU do not come up which I believe is due to MAINON & SUSON being missing to turn these supplies on..

What I am un-sure of is what is the ITC chip waiting for to send out these signals, what are the requirements?
I have checked these lines in diode mode and they seam normal -> 600.

I have checked to see if they come on for even a fraction of a second...

Hey there,
I'm largely still a student and unsure about identifying components like this, anyone have any idea what this is and if I have another one, fairly straight forward to swap out?
From my Bambu Labs AMS - had connected the wiring incorrectly .. Whoops!

Cheers!
