I have a locked BIOS from an HP800 series G1. The BIOS has both an Administrator and a User. I managed to unlock the Administrator using the HPUnlocker tool. All I can do now is enter as Guest User. Can someone kindly clear the user?

Re: locked BIOS from an HP800 series G1
Just to clarify this is the BIOS from the HP EliteBook 800 series G1 notebook (HP 820/840/850).
Not the EliteDesk 800. -

Re: locked BIOS from an EliteBook 800 series G1
Cool, thanks for replying my question. For a moment there I thought I was speaking Chinese and no could understand what I was asking.
Thanks for your effort at preparing this binary for me. Unfortunately it did not work. The only difference now is user string Sam Mason has been substituted for a blank string. The user password is still expected. Did you just replace the user string by hand? Or do you have a specific tool that you are using? It would be good to have this information but if it's proprietary and if the IP is yours then you're by all means entitled to said position.Comment

Re: locked BIOS from an EliteBook 800 series G1
Actually there is a trick to solve this problem. You need to set a fresh BIOS Administrator password. Then login again as Administrator using your new password and then delete users and their corresponding passwords from there on. So this is perfectly sound and logical so long as the device can be fully accessed as the Administrator.Comment

Re: locked BIOS from an EliteBook 800 series G1
I personally hate what the industry does with BIOS passwords. Setting passwords renders system next to useless in the event that passwords get lost. The security gains from setting BIOS passwords are questionable at best. In the end it's an immense waste of resources.Comment

Hello everyone.
In the last 8 months I have manually flashed about 150 HP laptops (BS series, Probook, Elitebook and Zbook). There are about 50 HP laptops, as I have already written before, they have been automatically flashed through windows updates.
Approximately 15% did not start after flashing.
I got the HP Pro, Elite and Zbook to work again with the exception of one using the familiar key combinations or the well known bios flash stick methode.
An Elitebook 840 G6, like many HP notebooks from the BS series (exclusively those with dedicated graphics c...03-08-2024, 10:49 AM -
Greetings badcaps community,
I havent done this for a long time and want to start it all again, after some evil and annyoing illness.
So I apologize in advance, if some phrases might sound a bit like gibberish or illogical to you.
Im trying my best to fully describe what I plan to achieve and hope I was choosing the right sub-forum for my new adventure.
I have a Elitebook 820 G1 and a Elitebook 840 G2 here.
These ask for a password when entering the BIOS, but boot just fine from the internal SSD.

Hello,
I have an EliteBook 850 G5. After a Windows update, including a BIOS update, the notebook turns on, but the screen remains black, and the fans spin at high speed—nothing else happens.
I assume the BIOS update failed, so I searched for the BIOS chip.
I found a Winbond chip located between the RAM and the hard drive, which has a size of 32 MB.
However, the BIOS update available on HP's website is only 17 MB in size. I used the update version that was previously installed when the notebook was still working.
