Hi, would like to try a little different oprative system, but can not do it because bios are password protected. Can you help me unlock it?

For that Model, you will need to Contact HP Business support - they should be able to send you a customised SMC.bin file which you can use at boot to reset the password.


You can contact HP Business Support in your country via




Just to note, don't try removing the rtc battery.  It won't remove the password, but it will reset the clock - as smc files are time coded, a large disparity between the system clock and the time encoded in the smc will cause it to fail.
