Product: HP Laptop 15-ef100la

Hello, I need help recovering the BIOS password for an HP 15-ef100la laptop. After three incorrect attempts, the system gave me the following error code:

System Disabled: D255AD57

Could you please provide the master unlock key or instructions to clear the BIOS administrator password? Thank you very much for your support!

Hello @GustavoDinotec ,

 

Welcome to the HP community.

 

A quick community search for the terms BIOS & Password finds all these posts >here<, which are mainly closed.
