HP 620 BIOS Password (Authentication Failed)

[Candeh]

Hello,

Couple of weeks ago I received an older laptop HP 620 from my sister. While everything works great I can't get into BIOS as we both forgot the password. Some users say that after 3rd try you get specific error code for master password. In my case I only get On-Screen Keyboard after 3rd time. If I press Enter again I get this:

Authentication Failed

System Locked

Press the power button to restart the system

I have already try to remove CMOS battery for 5 minutes with no luck.
Is there anything I can do to avoid replacing BIOS chip?

Thank you,

Can

You will need to contact HP and they should be able to send you a customized SMC.bin file which you can use at boot to reset the password.

When talking to the HP rep ask them to escalate your service request.
