T470 bios needed

[Nino RIcca]

Hello.
This laptop starts normally, the power button lights green, and the fan turns on. A few seconds later the power button light goes out and the fan stops spinning, the laptop never boots and the screen stays black. The laptop was working untill a windows BIOS update failed, I'm looking for a clean BIOS bin file or a clean up of the corrupted BIOS dump. Any help would be greatly appreciated Thank You.

Dear Friends., working on a Lenovo T470. All required voltages are present & the require Amps (.95mili amps), Also goes through the start process, turns off & then turns on but no display or any beeps. I think the BIOS Bin files are corrupted & has to be re-build. Can some pls. re-build the Bin File, Original Bin uploaded. Thanks in advance.

Hello.
I came to a very weird situation with a T470.
Laptop worked great but locked, backed up the BIOS, successfully verified it, patched it with Autopatcher, boot successfully and completed the DXE procedure, flashed back the old unpatched bios and now only the green led of power button turns on and nothing else.
Tried CMOS reset but no luck. No physical damage around BIOS chip, i was very careful and checked MB on microscope.
Any ideas?

Both bios attached
