HP Recommended
Product: HP 620
Operating System: Microsoft Windows 10 (64-bit)

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
