The HP ProBook 650 G5 belongs to a generation of laptops that use a chip and non-volatile memory to store security credentials. Unlike older laptops where you could simply pull a "CMOS battery" to reset the BIOS, the 650 G5 stores the password in a way that survives power loss. Method 1: The Official HP SMC.bin Method (Recommended)
Note: This method may fail if "Password required for modification" is strictly enforced within the existing BIOS settings. Method 4: The Hardware Route (EEPROM Flashing)
, with its robust Intel-based architecture, does not respond to simple methods like removing the CMOS battery.
For IT administrators managing many HP systems, the HP BIOS Configuration Utility (BCU) is a powerful command-line tool that can manage BIOS settings, including passwords, from within Windows. To reset a password: hp probook 650 g5 bios password reset exclusive
Method 2: The Backdoor/Master Key Generator (Software Bypass)
Proceed with confidence, but with caution. The password may be gone, but the responsibility of data security remains.
Use a "BIOS Hex Editor" or a specialized tool to clear the password hex string. Flash the modified firmware back to the chip. Method 5: Motherboard Replacement The HP ProBook 650 G5 belongs to a
The BIOS, or Basic Input/Output System, serves as the gatekeeper between the hardware and the operating system. On the ProBook 650 G5, the BIOS password is not stored in volatile CMOS memory, which could be cleared by simply removing a coin-cell battery. Instead, HP utilizes a non-volatile flash memory chip (TPM 2.0 integrated) that retains security credentials even without power. This design is intended to prevent unauthorized users from bypassing security through physical tampering, making standard "battery pulls" or "jumper resets" ineffective.
They will ask for your Serial Number and UUID . You can find these by pressing F1 or F10 at the locked BIOS screen. The Key: If approved, HP sends a customized SMC.bin file. The Reset: Format a USB drive to FAT32. Place the SMC.bin file on the root of the drive. Plug it into the ProBook while it's off.
While traditional methods like CMOS battery removal are ineffective on this modern laptop, software utilities (HP BCU, DOS-based tools) provide a less invasive option. However, for a guaranteed fix, learning to use an SPI programmer such as the in conjunction with RCUnlocker is the ultimate, professional-grade method. It completely bypasses HP's security and returns full control of the hardware to the rightful owner. By following the steps outlined in this guide, you can successfully unlock an HP ProBook 650 G5 and restore its functionality. Method 4: The Hardware Route (EEPROM Flashing) ,
Note: Tampering with the motherboard may void your warranty. If the device is under warranty, contacting HP Support with proof of ownership is the recommended path.
Modifying BIOS hardware or using third-party patching utilities carries a risk of permanently bricking the laptop motherboard. Ensure you work in an anti-static environment and always verify your chip read backups before writing new data. Only attempt these resets on hardware that you legally own or have explicit permission to service.
