BIOS Password recovery

ProBook 450 G1
Microsoft Windows 7 (64-bit)

Hi there folks.


We have 2 laptops (1x Probook 450 G1 and 1x ProBook 650 G1) that have been returned to us after WFR meant they were no longer required by the users. Unfortunately they both have BIOS passwords installed and of course nobody thought to check with the users before they left the company. 
Is there anyway of resetting the the BIOS Password so that we can re-use the laptops?

BIOS Password recovery

Welcome to the HP Support Community @CA992643


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 >>


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.
