Anyway, I'm not going to take the laptop apart and analyze the internal microphone hardware to make sure that the switch actually disables the mic. So even in that case, I'd assume the mic was still on even if the switch was in the off position.
On the other hand, I'd prefer to buy a laptop with a hardware switch for the internal microphone, if one existed, as it's better to have such a switch in case it actually does work as advertised.
