Boot Bios Admin Password

[uk51]

ProBook 6570b. Recently Bios got updated, reset to default and Admin Password created. How this happened I dont know as I have never set a BIOS  admin password on any system.

Have tried 3 attempts on BIOS login but after 3rd attempt I do not get error code, I get on screen keyboard followed by 'System Locked' notification and I have to power down.

Any ideas?

Welcome to the HP Support Community @uk51

For that model you will need to contact HP in your region and they should be able to send you a customized SMC.bin file which you can use at boot to reset the password.

Contact Support >> http://www8.hp.com/us/en/contact-hp/ww-contact-us.html

When talking to the HP rep ask them to escalate your service request.

Just to note:

Do not try removing the RTC/BIOS battery.  As it will not remove the password, but it may reset the clock and as SMC files are time coded, a large disparity between the system clock and the time encoded in the SMC may cause it to fail.
