Forgot bios password and power-on password

[luanvv]

Dear supporters,

I accidentally forgot my bios password and power-on password. Now, I have only fingerprint to access my device.

Please help me remove bios password.

Thank you so much

Zbook 15 G3 has very stringent security....have you set up a fingerprint scan to access power on/BIOS or just Windows? 

[luanvv]

Yes, I had a power-on fingerprint 

[Huffer]

And BIOS? You should be able to get in and change password using the fingerprint to validate the changes.

only power-on fingerprint. Bios login does not have fingerprint option, only password is acceptable

Well the security on the mobile workstations is very stringent. I am not aware of any backdoor passwords. Maybe someone else like maybe @DavidPK can help better or confirm what I suspect???

Hi,

I'd completely agree with @Huffer

There are no 3rd party tools that will work for this Model, no Backdoor or halt code.

The best option would be 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.  The only alternative to requesting a smc from Business Support would be to replace the bios chip.  You can contact HP Business Support in your country via

or

Just to note, if you do intend to go the HP route, 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.

Thank you all. I contacted to HP support center and they required me a order bill which I did not have. May be I should try to remember my password.
