HP Recommended
Operating System: Microsoft Windows 10 (64-bit)

Hello,
I own an HP ProBook 640 G1 laptop. Unfortunately, you have forgotten the BIOS administrator password.
After entering the wrong password three times, my system shows a System Disabled code on the BIOS screen.
Here are the details of my device:
Product Name: HP ProBook 640 G1
System Disabled Code (Halt Code): [system locked press the power button to restart the system]
Could you please provide me with the master password or the proper procedure to unlock the BIOS?
Thank you in advance for your support.
Best regards,
