Help me plase

solved with Harware User Manual:

You're Welcome. First you got to lenovo website and download the bios image using your serial number. After that you should extract the FD file from the exe file using innoExtractor. Then you cut the bios region from the downloaded file, and replace it with your dump bios region using UEFitool or any hex editor. Next you should move your DMI from the dump file to the new one, then clean ME Region using a proper versions.

ThinkBook 13s G2 ITL Corupt Bios Issues

Hello,
I have issues with my Lenovo ThinkBook 13s G2 ITL Type 20V9(S/n:R911EP86),
when i updated its bios(F9CN46WW Old Bios) with this new one(F9CN54WW) using a faulty battery pack in place, it completed the bios update process and on restart the screen only glows and doesn't display anything not even the "bios self healing screen".
As for now the laptop is rendered unuseable.
Any help or assistance from you will be of great value.
Thanks.

Attached is the latest Bios update Patch i used.

Good afternoon colleagues, I have this Lenovo Thinkbook that is experiencing the following issue: the customer was installing updates when it shut down due to a power outage. Upon turning it back on, it no longer displays video. We have tried BIOS updates from this forum and others, and while it does display an image, it does not recognize the NVME drive. We have already attempted several BIOS versions. Could someone assist me?

Hi, Just some more information about my issue. The laptop completely doesn't turn on, when plugging in the charger the orange charging light turns on but nothing more.

My laptop also is a ThinkBook 13s G2 ITL. I have tried the bios listed above and the others but none work. I would really appreciate the help.
