Hi,

would a corrupted BIOS prevent booting or showing some sign of life for a L480?

Here's your New Bios, try it and give me the results.
This device is L480 not L580, next time find your device thread and post there or create your own.

If your device Model is L580, why your file name is (E590)?
Also Serial Number is Wrong! It must be 8 not 7 letters.
