No questions is stupid ^^
If the LED is orange it means you have connect24 activated, meaning that the wii will update weather, news etc. while in standby and you will also receive letters from Nintendo. When the blue light flashes, it just means that there is an update, i.e. a letter or a system update. Just turn it on and off again and it should stop or maybe you forgot one update. To turn off connect24, just go to setting, I believe its second page named connect 24, there you can also adjust the blue flashing to go faster or turn it off. To read the letters just click on the calendar button in the start screen. Hope I could help you and hopefully you enjoy your wii a long time :)
edit: Oh great no other comments did show up for me two minutes ago but since they were all written a hour before I have to blame the site ;) and say sorry for posting to something solved :)
