HP ProBook 4320s BIOS Password Reset

[Rounted]

Hello,

I forgot my device's bios password. I want to reset the password. I tried it as a hardware but I did not succeed. 

I wrote using Google Translate because my English level is low.

I am waiting for your help.

Hi,

In that case, your 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.

You can contact HP Business Support in your country via

or

@Rounted

Did you try the SHOTGUN method???

If you did and it failed let me know so I can add it to my list.

Sorry @Rounted

The ProBook 4xxx series is one of the hardest.

On Monday I will have someone in the warehouse see if we have one I can test on.

I guess it's time to go to the warehouse and start pulling models that are not on my list and start testing them.

Thank you for your interest. I sent an email to download the smc.bin file.
