    I know this has been up before, but my BIOS simply doesn't have such a setting, so I don't see any way of getting rid of the extremely annoying double-beep that my preboot hdd password screen produce, than cutting some wires inside my laptop. (Obviously I'm not speaking about my built-in multimedia speakers but about the one that goes "beep!!!" in certain special cases.)

    Can anyone tell me if this can be done in a nondestructive way? Also, any hint to where I might find the little s.o.b...?

    Actually, most laptops do not have modem speakers. Simply a modem chipset is used directly on teh board, which is linked to the speakers in your laptop. Since the modem is directly connected to the speaker, the speakers will sound even if you mute the audio.
    You can try taking your laptop apart to find teh speaker, but I doubt you will be able to, since 95% of laptops do not have modem speakers anymore, only the old ones do, and I am talking 7 years old or more.

    Depending on what your laptop is, there might be a way. If you can find the speaker, follow the wire(s) back to the point where said wires attach to the motherboard. You'll find a socketed connector.

    Unplug it.

    Tape the connector down to a nearby plastic part so that you don't have a loose part inside the laptop. Use electrical tape for best (safest) results.

    However, obviously you won't have any sounds then!

    As Greg said, you would have no more sound coming from the laptop except getting external speakers or headphones, and that kinda beats the having a laptop thing.
    But , if they`re onboard,I don`t think you can disable it short of performing micro surgery on the mainboard.

    I've discovered by listening for the sound source, that, yes, the sound does come from my regular internal speakers and "subwoofer". This is terrible news, since my BIOS (American Megatrends) has little more options in it than boot order :( :(

    I know I'm not the only person with this problem. Many people want their data to be safe if someone steals their laptop, but full system disk encryption is a difficult matter, especially with Linux. The hdd security feature is a great solution, but the beeps are a big problem if you're in class or in a meeting - and they are also very annoying in daily use.

    Can anyone tell me any possible way to disable these beeps? Any way of modifying the specific BIOS option in hex, any kind of firmware upgrade or whatever?

    (By the way, my notebook is an LG R700...)
