Hello. The "NM-C821 DUMP" post on the site shows a corrupted picture and then remains black, but it won't open again. Attached is the E8CN18WW picture.

Then I found this thread and did as instructed, but no picture appeared. Attached are the files. Did I make a mistake?
(There is no picture in my original bios backup) There is no label on the case. When I opened the BIOS from the website (by copying the DMI), I wrote down the serial numbers...

Hi,

I have a Lenovo IdeaPad 3 17IADA05 (81W2) with a BIOS problem.
S/N : PF2LSSVK

The laptop powers on, the fan runs and the screen backlight turns on, but there is no display, no Lenovo logo and no POST.
and I cannot enter BIOS with F2 / Fn+F2.
I now have a dump from the original SPI chip and I’m hoping someone can help check, repair or rebuild it so the laptop can boot again.

Thanks in advance....
