i set up an administrative password in the BIOS setting. everytime i boot my HP dv laptop, it beeps loudly to prompt me entering a password. how do i stop this? i checked the option in the BIOS but there's none. this is annoying. everytime i start my pc it gives an extra loud beep. plus my HP lapatop is not equipped with the physical volume toggle. it's a touch pad type. i cant mute it before i power on the machine.
