I am having an issue where I am using the hp.probook.elitebook.bios.password.reset.utility.hpbr, but it is not working on my desktop computer. When i use the script on the desktop computer, it will not connect the device to the usb port of the laptop that has the bios file, and if i run the script on the laptop, it will not connect. why is this happening and how can i fix it?
By default, the script will scan for possible BIOS password locations to attempt to clear. If you are using an HP EliteBook with a pre-installed BIOS password, it will not attempt to clear that password because it does not know where it is located on your computer.
Registry key can be set in HKLM.Registry://HKCU.Registry/Machine/System/Library/Core Services/Setup/System/BootLogo/BIOSInfo/SystemBIOSPassword/AutoManagement/Password:Key=Probook_Elitebook_8440P_8440P_Machine_ SystemsBIOSPassword/AutoManagement/Password/ObfuscatedPassword:Key=Probook_Elitebook_8440P_8440P_Machine_ SystemsBIOSPassword/AutoManagement/Password/ObfuscatedPassword:%Text%
Here is an example of how the password should be entered into the setup utility. Notice the mask or obfuscation is in place by default. If the password should not be obfuscated, the mask character can be changed or removed.
Here is the script to backup bios passwords using the hp.probook.elitebook.bios.password.clear.utility.zip Mazzif created for full functionality. The first 2 methods should be sufficient, since the variable size passwords can be stored in the same location. Be aware that this approach does NOT overwrite the existing passwords with new ones. If the BIOS password is > 16 characters it will take the entire parameter as a passwort. With most models, however, you will only be able to store 2 characters. Even though you can store up to 16 characters in a variable lenght password, only the first two characters are stored as the password. If the first two characters are not correct, then the remainder of the password is not used. The script DOES NOT support for any other models. Visit this [ Post ] for more info. The next 2 methods work for Full variable length passwords. The first one overwrites all existing passwords on the BIOS setup with new ones. The second method works just fine if only the first two characters of the password are correct. This script works for any models, and supports the new variable length passwords.
I used to have a similar problem to the one above, where I forgot my HP BIOS password. But, I found a really neat utility that I used to easily reset my BIOS password. The utility is called HP BR, and it is a free download. I used this utility to wipe out my password in record time. If you have also forgotten your HP BIOS password, you can use this utility to reset it.
This section is where the script enumerates all the BIOS classes that are specific to this model and finds the one that you want to manage. For the HP ELITEBOOK, there are 12 classes that you can query and modify. If you have another model, you may need to adjust the script accordingly.
The script requires classifications, enum, and registry that are specific to the HP ELITEBOOK model. If you are not using this specific model, you may be out of luck. I am not aware of other products that have these classifications.
Another limitation is that the script requires administrator privileges. That means that you will be prompted to press ctrl+shift+enter before it can be executed. With this limitation, you cannot run the script unattended. This may not seem like a big deal, but as you know, the use case for this script is to reset a forgotten or incorrect BIOS password, so you want to be able to run the script safely without any prompts. This limitation will be covered in future posts.
This section uses the results from the previous section to query and modify the specific class. In this section, the script will ask you for a BIOS password, ask if the password is correct, and make any necessary changes. To start the script, click the below button.
