Have you some other location?

I will update the post here, but I leave it mostly for historical purposes.  My main point for up to date information will always be my (Youtube), and the thread over at MDL.

Hi! 

how can I force BIOS update on HP Elitebook XX30 series? 
I'd like to remove BIOS passwords, but they show all the time: 
"The current BIOS doesn't support this feature"

Thanks! Smile

[INTRO]
My story begins as this:
A few months back, I got an HP Core i7 Probook 6550b from my dad (that he picked up 2nd hand). It had a busted display though. Upon repair, it was found to be BIOS Password protected. And thus began my quest. Long story short here, I did what I set out to do. I was able to reset the TPM, and clear the password. Along the way, I have applied my technique to a few other models and have confirmed successful TPM reset. This is a software based solution. No disassembly, or removal of any parts (unless your boot order is locked, then there is a little work to be bone, see end of post)


I have outside confirmation that my utility works on these models.

[CONFIRMED]
Elitebook 6930p :New
Probook 6470b :New
Elitebook 8560w :New
Elitebook 8530p :New
Elitebook 2560p
Probook 6550b
Probook 6460b
Elitebook 2560p
Elitebook 2740p
Elitebook 8440p
Elitebook 8640p


And I am confident that my utility will be successful on these listed models as well, but I need help testing.

There may be more.

[LOCKED BOOT ORDER]
If your BIOS has a locked set boot order, and will only boot to HDD, you need to take a laptop sata drive and use an external adapter and make it dos boot-able on another host machine also placing the files on this drive, then replace the internal hdd with your created dos boot-able HDD. Powering on the machine will boot to the dos environment. Using DOS commands, navigate to your files and execute them following directions on screen. BIOS will be free of passwords, TPM will be cleared.

[OTHER]
I have a set of 'test' files that may be used on models other then the ones listed here as kind of a fisher. We could tell from a resulting error if we would have success. If you would like to try a model other then what is listed, PM me your UUID and SN.

[USE]
To use this system, select your supported hp probook/elitebook model from the dropdown list. The Serial Number field and UUID Filed will populate with data and will need to be changed to that of your own laptop's. You can get your UUID and SN usually by pressing F1 at system boot. If not, use the included 'HPSET146.EXE' utility included in the 'tools' directory. This must be run from DOS. Once data is entered into the fields, click the patch button and a file will be created in the /output folder. Take the exe file and copy it to your dos bootable media (usb/cd/floppy). Boot to DOS and run the created file.

Inside the /tools directory you will find some tools. A utility to create USB Dos bootable thumb-drives, a windows 98 boot cd iso, and a tool to get SN and UUID.

/backup directory includes four *.bin files should the ones in the root directory get corrupted. just copy to the root dir in event of corruption.

[DISCLAIMER]
There may be unforeseen negative results stemming from use of this system. By downloading and using my tools, you agree to use them at your own risk. This was originally for myself, but I have opened up to the community. I am not a professional programmer. There is no guarantee of success using this tool, even on units that are marked as 'confirmed'.

Thank you for looking. I welcome all feedback good or bad, just trying to help people. Cool

Hi

First of all, thank you for an amazing thread!

I need to reset CMOS password of an HP ProBook 650 G1, I don't see any support for this specific model in your tool, can you please advise me further?

Is it safe for me to try this tool on said HP ProBook 650 G1?

Kind regards
