Surface Laptop 4 BIOS rebuilding AMD

BIOS/UEFI Modding BIOS Modding Requests

microsoft surface laptop 4 model 1958 is boot looping and wont enter Bios/UEFI.
I have a backup from the corrupted Bios (AMD chipset). What is the easiest path to rule out a BIOS issue?

  1. Can I burn another working 1958 model BIOS (downloaded from internet off another 1958 laptop) and at least be able to get into UEFI on this laptop?
  2. Or do I need to update the “another working 1958 model BIOS” with DMI information (serial number, windows activation key, etc) first before it even gets into UEFI screen?

Please advise. Thanks

so back in May what was the answer? BIOS looks ok so the problem is in the HW?

How about the question I was asking, can I try the internet BIOS for the same model and would it even get to UEFI settings screen without having to update anything from the OLD BIOS?

Can you try…? Sure, whose stopping you here, its your asset and your decision ONLY, not a forum rule or a forum user decision, yours’s only sir.
Does it work… who knows…
Does it need any data from old backup…it should matters to anyone who is willing to keep the original system data, OS lic, sn, mac, uuid etc.
That’s it, nothing more to add, you can wait for other users contribution, good luck.
