YES, I am talking about the system beep at start up. YES, this beep is a bios signal. NO, you don't need a special bios setting. The sound button disables it to AND the red light indicates that the notebook is complitely quiet. There are some other beeps, for instance after resuming from suspend to disk. And they are even off if the red light is on. The state of the red light (sound on/off) is stored somewhere in the bios. It keeps its state also after a reboot. If the light was on before shutdown it keeps this state (on) also after powering on again. BUT: this behavior is only valid for Windows. If the state of this red light was off before doing a shutdown it is off also after power on. You can press the sound button after power on during the first BIOS messages so that the light is switched on and you get rid of the BIOS beep. But then comes Linux. If you select Linux in Grub the light gets off almost immediately and you will hear every system beep afterwards. Pressing the sound button in Linux enables/disables only the sound but not enables the system beeps. The annoying thing is not the missing red light but these beeps especially if you are in a silent environment or a train. And: it has worked some times before in Ubuntu 9.10! So, why not now with a recent kernel?
