Gracias por la ayuda, estaba leyendo que al tener distintos dmi con el tiempo trae problema, es posible modificar mi bios y arreglarla manteniendo todos mis datos? solo arreglar la parte del voltaje que toque? gracias!!
Thanks for the help, I was reading that having different dmi's causes problems over time, is it possible to modify my bios and fix it while keeping all my data? only fix the part of the voltage that touches? thank you!!

If you can`t use a hex editor you can still add the DMI yourself using this guide https://www.badcaps.net/forum/showthread.php?t=116311 .
Follow the Easy guide and use the attached script.

Hi
Please help me fix this BIOS!
Lenovo Legion Y740-15IRHg
I have attached the faulty bios!!!
Officially, from Lenovo's side, it was done by automatic BIOS update. After the update, the machine does not turn on, the cursor in the top corner of the display flashes rapidly! and then black screen
Can I do anything with it? or the video card of the machine is faulty! Can you disable the NVIDIA video card in the Bios completely to leave only the Intel card.... ??

Thanks
