Hello people.

I own a Lenovo B590 and I want to remove the battery check from EC and the wifi whitelist.
These are the specifics:

Code:
Product: LENOVO B590
Model Name: 62742BG
BIOS: H1ET69WW (1.12)
EC version: H1EC31WW (1.11)



I performed a BIOS backup using Universal BIOS Backup Toolkit 2.0 and this is the generated file: https://file.io/UuEIYpnvmQyv
I'm not sure that's enough to provide me a patch, in case let me know what I should do.

Thanks in advance
