"Not quite," Elias muttered. "Most older ProBooks, you could just yank the CMOS battery. Wait five minutes, and the volatile memory clears. Password gone. But the G6 generation? HP got smart. They use non-volatile memory. The password is burned into the firmware. You pull the battery, you wait a week, you put it back… the password is still there, laughing at you."
For the G6 series, the password is stored in a non-volatile EEPROM chip on the motherboard. Unlike older desktops, simply removing the CMOS battery will clear this password. Leave the laptop on for 30 minutes, then restart
HP ProBook 440 G6 , resetting a forgotten BIOS password is more complex than on older models because HP store security credentials in non-volatile memory (EEPROM) that is not cleared by simply removing the CMOS battery. HP Support Community Exclusive Reset Methods
