BIOS password

HP Recommended
Probook 6570b
Microsoft Windows 10 (64-bit)



I recently bought a used HP Probook 6570b from the Norwegian equivalent of Ebay. My issue is that the BIOS is locked with a password. CMOS does not clear it. Failing the password does not provide an error code. I'm stuck.


Thank you for reading and any and all input.

Welcome to the HP Support Community @Bla0


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.

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.

Alright, so the answer I got was that the guarantee had run out and the only thing they could do was to replace the system board. Guess my next step is ordering another chip and a programmer.
