Thank you Peste for your effort and the quick reaction but unfortunately the new bios with autpatcher isn't working.

I read somewhere in the forum that the Macronix chip could be the problem.

Has anyone solved the password problem in bios with lenovo P52. Autopacher does not work, a melody is heard when the laptop is started with a patched bios and now picture on screen.

in post 36 I posted both bios files.

Hi,
I've got the same Problem with my P52. When I flash the autopatched file i get this melody and the screen stays black. Maybe someone could help with my file?
I attached both the original and the patched file. After reflashing the original dump the system starts with a locked bios.

try chk

maybe even on this model the pins can be reconnected and the bypass password can be done

[dejankeke]

try chk

I tried, but the laptop starts up and shuts down immediately.


here is my original bios with password

[Maxpower3]

thank you for your efforts, the result is the same, the melody is heard and there is no image on the screen.

is there any solution?

try chk

[dejankeke]

try this file and follow steps from autopatcher. Use original adapter or >130W

Hello 👋🏻
Is there anyone left here that could help me remove a password from BIOS? I've found some .bin files online, didn't help...in addition, I've only located 2 chips on the motherboard one 32MB and another 1MB but in the downloaded bios dumps there were three files 32MB, 1MB and 256Kb... I don't even know where the third Chip is 🤦🏻 I have the 32MB and 1MB bin files I'll compress them ans post here if it's enough. I look forward to an answer and we'll go from there. Thanks

PS Disassembly of a Lenovo ThinkPad P52 is a BIG PAIN IN THE A** 🤣
