This has happened twice so far. The last time I had my Wii on was 9/14/09. I went to turn it on today and it would not turn on. The power LED was yellow and I could eject or insert a game disc. I called Nintendo, they had my unplug the A/C adapter from the wall for several minutes then plug it back in. Everything is now working fine. However, why has this happened twice? Any idea what causes this? WiiConnect24 is on and with standby connection set to on. Nintendo Customer Service said the unit does not need repair. Thoughts?
