Skippy722 is right, also when you put a disc in it will flash for a second or so. You can stop receiving messages from Nintendo by selecting the option to 'stop sending messages' (or similar) on the message itself. Once you have played your wii for more than one minute, a message will appear telling you how long you have played and on what game/channel. These messages however do not make the disc drive blink as you cannot delete them.
