Hence my suspicion it's in the BIOS. It doesn't > have to be visible to the user, at all. Actually yes, it needs to be visible to the user and no, it probably should not run during boot. If user is in plane/train, accellerometers will basically detect problems all the time; still you want to use the computer. (And you still want the machine to boot => default == fall detection off). IIRC there's windows program to control it. -- 64 bytes from 195.113.31.123: icmp_seq=28 ttl=51 time=448769.1 ms
