Thank you.

Your bios backup is empty - full of zeros. Read the chip again.

Hello, I would say this is the wrong chip.
In their newer notebooks, Dell again divides the ME Region and Main Bios into two chips each.
There would have to be two chips, one with 16MB (128 SOIC) and one with 32MB (256 WSON 8 QNF CHIP).
The chip with the 32MB is required (256 WSON 8 QNF CHIP), only that can be put into manufacturing mode.
