BIOS Password lost for Elitebook 840 G3

[Pieter2000]

I tried to update my BIOS but I had first to enter the password for the BIOS.

However, I haven't that password anymore. 

Is there a way to remove/change/reset the BIOS Password?

Any help would really be appreciated!

Hi,

You'll 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

or

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.

Hi,

I have the same problem as the original poster. I received today the SMC.bin file form the customer service. I managed to enter at least to the BIOS with the file, but when I try to "Change BIOS Administrator Password" or "Restore Security Setting to Factory Defaults" both of them requests the original BIOS password what I obviously does not have.  What am I doing wrong? I would really appreciate any suggestion what to try, because this situation really makes me upset.

Below some screenshots about what I see:
