When I turn on the mini it starts up but quickly will turn back off again. At times it will get to the windows start screen but then again it will turn off by it self. Almost like a loss of power. I have tried a reset like some other people on forums have suggested with no luck. This is removing the battery and ac power, holding the power button across to turn on for about 1 min and then connecting power and battery back. Still perform the same turning on and off. Any ideas?
