Legion 5-17IMH05H

[DAMIGO]

Good evening together,

I kindly ask for support regarding the BIOS. My Legion-5 just start and after some seconds switch off no BIOS, no NOVO Button reaction,
black screen. I suspect maybe a corrupt bios or you have some more ideas for looking into or to resolve it..
I remember that it happens when I selected before the option for restoring optimized BIOS setting, before it went completely off to bricked mode.

System: I7 10th Gen., RTX2060
Model: 17IMH05
Type: 81Y8
Serial: PF24TPH0
MTM: 81Y8007PGE

I have add the original dump (approved by 3 time rereading from chip) and also the latest BIOS.fd from the Lenovo Page.
Please help and prepare it for flashing via CH341A Programmer (using AsProgrammer).

Am not sure what else needs to be transferred from the DUMP bin file to the fd file and how needs to be modified for programming.
Also regarding to the issues what happens, needs it a reprogrammed EC or something else so that the machine starts with good values.
Would be mega happy to ressurect this laptp.

Kind regards

First! A huge Thank You for your fast work!

Sadly i have still the issue that the power main button enlight at pressing it and after some second get sqitched off again. Screen stays black. I could programm the bios Chip with an external programmer (desoldered, programmed with reading back the bios and compate it, re soldered back) and still this behaviour.
