As i read does we all think that the bluetoothmodule that the wii use does some magic inside while the wii is in standby and if the powerbutton is pressed it wakes up the wii. so, there are bluetoothmodules replacements fpr the wii for about 15$ in the shops. you should try to get one, sync a wiimote to it (as far as i know, the brown button in the sd-slot is directly connected to this module)by dicky - Hardware
