acbc said:Which idiot will switch on a laptop and leave it running in the car? If standby, the power is off as well. Don't believe it? You take a multimeter and test the USB and PS/2 ports. No voltage activity during standby or hibernation.
So what's your point? Even if the PS/2 or USB port has power it still doesn't emit any RF signal which can be detected. Even IF the laptop does, do you guys think the signal can pass through your metal boot and car body? If you think so, try hiding in the boot and using a handphone see whether you can get a signal or not.
