lenovo legion 5-15ach6h bios request

[themosttogain]

Hi,

Another one with the same symptoms - had keyboard flashing but now just a solid power LED.

I've tried a couple of the good BIOS files from here just to see if I got any different symptoms, but issue remains the same so have provided the original BIOS dump for repair if anyone would be so gracious!

Model is again a Legion 5 15ACH6H - Serial number is PF468KP4

Not feeling particularly confident that it'll fix it now, but here's hoping.

Thank you.

Alan

Hi,

I have this laptop which kind of boots but has black screen on both built-in and through HDMI. I tried a few BIOS from this thread but none of them made any difference.

Laptop details are as follows:
Model: Lenovo Legion 5 15ACH6H
Serial number: PF3ZA928
MO:PF9XB2724064
Product ID/MTM/: 82JU0120MX
Main Board: HY660 HY561 HY572 HY56C HY57K NM-D562 Rev:3.0(2021-05-17)
CPU: AMD Ryzen 7
GPU : RTX3070 6GB (GN20-E5-A1)

I would appreciate if someone could check and repair original bios, if possible:

Thank you for your assistance! I was able to get picture on external screen but built-in one shows no life signs whatsoever, not even a backlight. It seems that I need to check for hardware failure in built-in screen connection.

Hello

Can someone take a look at my DUMP?

I tried using the dump from post 5 with a copy of DMI, but the laptop still boots without an image.
