Yes, it's ready to flash, S/N inserted, latest BIOS version
Erase - Program - Verify on AsProgrammer/NeoProgrammer software, make sure you get a good connection if using the clip

Make a good verified backup then flash the virgin bios from post 10 or this post - https://www.badcaps.net/forum/troubl...34#post3746434

Attached is a macro script that can copy the DMI (serial number etc) from your backup to the new bios, read the README.txt file how to use it.

Thank you very much, the laptop started up. Does this macro only work for the Lenovo Legion Y540-15IRH BIOS ?

It will not work with any, only if it has the same fixed offsets. Each model is different https://www.badcaps.net/forum/troubl...69#post1769669
