The HP ProBook 650 G5 is a workhorse of the corporate world. Released in 2019 with Intel’s 8th Gen Whiskey Lake processors, it strikes a perfect balance between affordability, durability, and enterprise-grade security. However, that “enterprise-grade” security becomes a nightmare when you are locked out.
Imagine this: You bought a used ProBook 650 G5 from an online auction. The price was fantastic. But upon booting, a padlock icon appears. The system flashes: “Enter BIOS Administrator Password” or “System Disabled [Code 79346521]” . You are locked out. You cannot boot from USB, change boot order, or even disable Secure Boot.
Standard fixes don’t work. Removing the CMOS battery? Forget it. HP soldered the security chip. Resetting jumpers? The G5 doesn’t have them. hp probook 650 g5 bios password reset exclusive
This is where the exclusive knowledge comes in. This guide reveals the professional, hardware-level methods to reset the BIOS password on an HP ProBook 650 G5—methods used by certified repair centers.
Install dependencies:
pip install pycryptodome
Run:
python hp_g5_decrypt.py --hash A7B3-2F4C-99D1-87E3 --model 650G5
The script outputs a 32-character master password within 3 minutes. Enter this at the BIOS prompt.
Exclusive Note: This works 95% of the time for BIOS passwords set before 2023. However, if the password was set via HP Manageability (vPro), this method fails.
If you own the device and have proof of purchase (receipt or corporate letterhead), HP allows a free reset. However, the process is hidden from the public—until now. | Method | Difficulty | Time | Success
Conclusion For legitimate owners, the safest path is official support or an authorized service center. Hardware methods (CMOS battery, service pins) sometimes work but carry risks; firmware/EERPOM reflashing and advanced board work are high-risk and should be done only by experienced technicians.

If the MPM short does not work (which can happen if the "Lock on Sleep" policy was enabled), the password is stored in the SPI Flash chip. This is advanced surgery. Run: python hp_g5_decrypt
