Product: HP Probook 6555b
Operating System: Microsoft Windows 7 (32-bit)
Hi,
Im trying to update the BIOS on my HP Probook 6555b, but get prompted for an admin password, which i do not know.
I have removed the battery and the RTC battery, however when i start backup i get the below error and the default admin password gets restored. Is there a way to reset the Admin BIOS password please?
The CMOS checksum is invalid.
The CMOS will be reset to the default configuration and will be rebooted.
Please check your BIOS Setup options to see if they changed.
CMOS Reset (502)
ENTER - Reboot the system
