I do not know if the boardview of GX650PI is also applicable to GX650RX because of different Architecture (Zen3+ for 6900HX vs Zen4 for 7945HX) that can lead to also different pin layout, I am not an expert on this so correct me if I am wrong.
Also, maybe you could verify the RAM?
Checking the IC U3001 (IT5125 Super IO Chip), it is the one powering up the GPU, but without the schematic diagram of this motherboard in the Power Sequence we cannot know if the Super IO Chip turns on the GPU alongside the CPU or after the initialization is complete....

Did you check if you have the correct voltages on all Power Rails? Did you try to reflash the BIOS on the flash chip, some laptops that I see on youtube after replacing the PCH Chip needed to reflash the BIOS on the chip, maybe it is applicable on GX650PY as the PCH Chip are on the CPU itself and you replace it?...Leave a comment:

Sadly, I cannot find it on digikey, mouser, rs-online, or even JLCPCB. I think you could find a replacement for this chip in donor boards only, or on ebay/aliexpress (but last time I check I could not find it there either).
Could you please perhaps share the measurements of the Voltage Rails on your unit? Thank you in advance. As I think I will need to do a CPU Replacement on my unit, and I will need a reference for the VDDIO_MEM_S3 Rail. When I get back home I will share an updated image to reflect all non-affected rails on my unit, so that you could also use it....Leave a comment:

Hello Guys, I would like to ask for help to anyone that has a Schematic and Boardview of Asus GX650PY, Basically I messed up when I was cleaning the fans and heatsink of the Laptop and made some drop of Liquid Metal in the Board. It cause a short, I already located the precise location of the short through measuring the resistance of all Inductors, the problem is that I cannot push through without knowing the schematic/board view of the Laptop. Also, I can inject a power through the Main Power Rail and see with a thermal camera the short because the short is also on the Main Power Rail, but I...Leave a comment:
