Resetting a forgotten BIOS password on the HP ProBook 650 G5 requires specialized methods, such as utilizing HP-provided SMC.bin files, employing third-party generators for "System Disabled" codes, or hardware-level BIOS chip reprogramming. Unlike older models, removing the CMOS battery is ineffective, making these tailored approaches necessary to bypass security credentials stored in non-volatile memory.

Suddenly, your $1,000 machine becomes a paperweight. You turn it on. You see the dreaded prompt: "Enter BIOS Administrator Password" or "System Disabled [Code: 89526234]."
Step 5: Flash the Modified BIOS
Load the modified .bin file into your programmer. Click Erase, wait, then Write, then Verify. Disconnect the clip.
The HP ProBook 650 G5 is an enterprise-class machine. Unlike consumer laptops, it stores the BIOS password in a non-volatile memory chip. Removing the CMOS battery does NOT work on this model. The password will persist even if the board has no power for days.
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.
