I have the same problem on my notebook HP 640 G2.
I bought an eprom recorder and tomorrow I must have it at home.

Re: hp Probook 640 g2 bios password
I tried to run your program, but it presents me with the following message.
"Failed to execute script HPUnlocker"
I use Windows 10 and I'm running as an administrator, I also disabled my Norton, but even in compatibility mode with windows xp or windows7 it displays the error message.
Attached is the original file.
Thank you for help.

Re: hp Probook 640 g2 bios password
Did you just download and open exe? Or drag and drop your .bin file?
Please read first post on how to use it.Comment

Re: hp Probook 640 g2 bios password
I'm sorry, I'm sorry, I'm sorry.
I didn't really pay attention.
I dragged the file to your program and it identified the "UserCred".
PERFECT.
Now I am recording the chip and then I will test the notebook.
Just an observation.
I downloaded several programs to read the bin files, but none of them could find the word "UserCred".
Only yours.
Thanks for your help!!!

Re: hp Probook 640 g2 bios password
That is because it is UserCred in unicode. That means it is written with 00-s in between each character. Thus it is actually seen as U.s.e.r.C.r.e.d
Hex editor or uefitool work fine for that, just use unicode when searching for UserCred or use regular string when searching for U.s.e.r.C.r.e.dComment

Re: hp Probook 640 g2 bios password
Hello my friends.
I read the original BIOS and unlocked it with the friend's tool, RethoricalCheese.
But when testing the new unlocked BIOS, the notebook won't turn on.
Even if you reset the original BIOS with the password, the notebook will not turn on.
When placing another BIOS that I got here on this forum, the computer turns on, but emits 4 audible warnings and the monitor does not turn on.
My knowledge is limited.
Please, could someone help me.
Thanks.Comment

Seems like you did not verify the file you read. So your backup is faulty.Comment

Hello everyone, I come here to tell you my problem regarding the power-on password. It is not a bios reset demand, and i can't have any access to windows. This is the bios and power-on password that is blocking all other things.
My Omen 15-dh0052nf purchased second-hand was configured with the bios password upon purchase (very simple password :P ).
Having decided to sell it in order to get something more powerful, I reset all BIOS settings and set a blank administrator password. But the power-on password cannot be changed to a blank one so I let the actual password set.... -
