The serial number is fixed, but the SSD issue persists. I'll have to dig in for some hardware repair!

Zephyrus G14 GA401QH-211 Bios missing serial number
Hi All,
I was told to post my corrupted bios dump here. My Zephyrus G14 GA401QH-211 is missing the serial number in the bios. NVME drives can't be detected by the bios either. The bios version is 410.
Serial: M4NRKD01530915H
Thanks in advance!... -
I use a CH341A. You’ll want one of the new ones with adjustable voltage.Leave a comment:

You can try flashing with a EEPROM programmer - but to me, it looks more like a hardware issue.
If you connect it to an external display, do you see anything?Leave a comment:

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