HP 15 bW032WM error eMMC malfunction

I'd really love to get this thing up and running! Just went black screen one day, can't access bios or anything.

Got an error message via the caps lock light that iirc traced back to Means eMMC - embedded multimedia card failure.

This is where my confusion comes in, web searches tell me this is for storage and came before SSD, was used on the first steam decks etc.

But the hard drive inside is a 1 TB 5400 rpm SATA according to HP and my eyes when I opened the case.

So I'm assuming, unfortunately that the embedded Radeon 7 graphics card is the eMMC the error is referring to?

Really hoping not because it's the most valuable part of the laptop to me right now. Assuming it is because the screen is black, can't access bios or anything.

If this is the case, am I 100% going to have to order and solder in a replacement or is there any way I could potentially save the eMMC/GPU?
