the original bios has 8mb, not 4mb... use an SPI programmer to extract the bios content...

I thought it could be done without unsoldering because I'm not capable, the bios that I flashed downloaded from the lenovo site is 4 Mb

excuse my ignorance, I don't have equipment to solder/unsolder from the motherboard, I can do it in another way..I'm telling you this because in another forum they asked me for money to do it with software like H2OUVE or Flash Programming Tool. Version: 10.0.30.1054 ,but I think the spirit of the forum is to help each other without asking for money

LENOVO G50-70 Bios Password

Hello,
i hope i'll be ok and not against rules with my request.
So i have a Lenovo G50-70 , S/N : YB08544882, MB model : ACLU1/ACLU2 Rev 1.0 with Bios Password locked.
I try with autopatcher and the result is : "Dump.bin is corrupted or does not contain a valid dump".

I think my model isn't compatible and some skills missing me to remove the password by myself.
Can someone help me to do that please?

Thank you very much.

Thank you very much. I'll try to find how and where is the DMI area. If someone else can help, that will be fantastic !
Thank again

I tried every file in this thread, but i got no luck. I have black screen that flickering at boot, no picture. I will upload original file, if somebody can fix it, so i can be sure that is the problem. I also tried other rams, other monitor, etc. All voltages seems to be fine. Somethimes after long waiting in that blank screen , he start normally. I think its cpu/gpu issue, but i would like to try one more time with BIOS.
MB is ACLU1/ACLU2 UMA NM-A272
SERIAL YB07183383
