Hi i have a HP Pavilion Ultrabook 14-b006sa and it's asking for a "Administrator Password or Power on Password". I have no idea what it is, I have a strong feeling my brother has been playing around with the laptop but he's denying all accusation.
Please help, some instructions how I can reset it would be much appreciated.
Thanks
