Zephyrus G14 GA401QH-211 reaches bios but has no serial number and can't detect NVME drives

[evilgenius31]

Hi Everyone -

I'm working on a Zephyrus G14 GA401QH-211. I bought it on ebay, knowing it only boots to the bios. The serial number is missing when I enter the bios. I've also attempted to use multiple NVME SSDs, but the bios can't detect them.

Does this seem like a software issue, or a hardware issue with the nvme slot / pcie controller?

Thanks!
