How to remove password BIOS UEFI HP EliteBook & EliteBook
HP BIOS Unlock [FOR DOS]

Well after some small delay, it's here. This is the successor to my Windows based solution (Original Thread) to reset HP Pro/Elitebook BIOS Passwords. I have tried to make this as simple as possible. So here is what my package HPBR.RAR contains.

It contains a folder with utility to back up and re-image a usb thumb drive.
It contains an image (HPBR.IMG) of my usb thumb drive.

My image was made from a 64MB drive, but it compressed super awesome, so now the rar package is ~500KB. Your thumb drive needs to be 64MB or larger! After it is imaged, it will become 64MB in capacity (IE: a 1GB Drive will become 64MB), and may require Linux DD to restore true capacity, but that's outside the scope of this tool, I say it more for informational purposes. I have support for these 22 models. A supported model does not guarantee compatibility however. If you receive a 'Model not supported' error, please PM me with the error code number.

[SUPPORTED MODELS]
Elitebook 4310s Elitebook 2530p, Elitebook 4510s, Elitebook 6930p, Elitebook 8530w, Elitebook 8460p, Probook, 6550b, Probook 6535b, Probook 6730b, Probook 6735b, Probook 6460b, Probook 8730w, Probook 2230s, Probook 2560p, Probook 6455b, Probook 8560p, Probook 2730p Probook 8440p, Probook 8530p, Probook 8540w, Probook 2740p, Probook 8560w

[USE]
Once your thumbdrive has been imaged with HPBR.IMG, boot your HP Probook/Elitebook with the USB Thumbdrive. You will be presented with a menu:
HP PRO/ELITEBOOK BIOS PASSWORD RESET
(c)2014 Mazzif
PLEASE TELL ME YOUR MENU CHOICE
1] FIRST RUN? 4] ABOUT
2] SECOND RUN? 5] SHOTGUN
3] RE-PROGRAM 6] EXIT
Selection number:


The options are mostly self explanatory.

1] If first time using the tool, use this. Some models require a second run, and it will tell you if you need to run again. If so, then choose '2'

2] If program instructs you to reboot and run again

3] If you receive a white screen during POST about missing or invalid system board information, use this option to reprogram your board. It may ask for Serial Number, Part Number (SKU), Asset Tag number, or ConfigurationID (If asked for Config ID, use 25 0's (Twenty-Five Zeros)

4] About my work

5] SHOTGUN
Runs all keys. Good for testing models not on the list.
6] EXIT
Quit clean



Option 1 brings up a second menu where you then select your model:
HP PRO/ELITEBOOK FIRST RUN
1 Probook 6550b 12 Elitebook 4310s
2 Elitebook 2530p 13 Elitebook 4510s
3 Elitebook 6930p 14 Probook 6535b
4 Elitebook 8530w 15 Probook 6730b
5 Elitebook 8460p 16 Probook 6735b
6 Probook 6460b 17 Probook 8730w
7 Probook 2230s 18 Probook 2560p
8 Probook 6455b 19 Probook 8560p
9 Probook 2730p 20 Probook 8440p
10 Probook 8530p 21 Probook 8540w
11 Probook 2740p 22 Probook 8560w
Selection number:

Select the number that corresponds to your model and press Enter. The system will do the rest.

If prompted to run a 2nd time, boot to thumbdrive again, this time choosing option 2, and press enter. Again, you will have a model selection choice. Select the number that corresponds to your model again, and press Enter.

I don't know what else to say here. This is my first C program I've ever written, so there may be some unforeseen bugs. My final line count was 1162 lines of C. I used Open Watcom C v2 Compiler. So far I have been the only person to test, and I don't have all 22 models on hand, but 11 of the 22 I did, so I did physically test those, and they all worked awesome. If you hit a bug or snag, sorry, let me know and ill fix it.

I hope you find my work useful.
