My MBP, purchased in November, 2006 (It's about three months and three weeks past the 3 year warranty!) has suddenly refused to respond to the power button at all. The adapter plug tiny green led glows when plugged in, so I'm sure it's getting power to that point. But otherwise it's completely unresponsive. I did the SMC reset and called and talked to tech support at Apple and he said I did everything he would've told me to do (try starting it with just the DC adapter power, and again using just the battery power, reset SMC). I'm pretty handy with this platform having done a HD replacement procedure a couple years ago, so if I can figure out what exactly the problem is, perhaps I can fix it without paying the high price for a technician to do so. What is the problem and how can I verify it? Thanks in advance to all responders, except the ones who are wrong... Oh, and does anyone know if Apple has any history of extending their three year warranty for things like this?
