That worked, fantastatic. Thank you very much for your help!

Hell everyone,

I have a All-In-One PC on my table which has suddenly a startup password which is unknown. I have no access to the bios or any boot medium.
After dissassembling the device I checked online to find some information about it but it seems to be a cheep chinese version and imported to the german market.


I give you all the information I have and hope that someone can help me to retreive the password out of the dump or patch it. Any other help is also much appreciated.

Update to my request:
Got it to work. I had to clean up the me region of my bios dump. After that everything works as expected. Thanks to everyone.

Re: HP Probook 450 G2 440 G2 LA-B181P BIOS

I have a HP probook 470 G2 with a bricked bios. I flashed the bios file from post #1 and the notebook works again.
Now I discovered that the AMD discrete graphics is missing. There should be a AMD R5 255M.

Does someone have a bios dump with amd graphics? I attached my broken dump if it is useful.

Hello everyone,

Greetings from Germany,
I started repairing notebooks a few month ago but I have to learn a lot more.
I'm glad that you share your knowledge and experience.
