Q: My Mac book will not turn on

See this Apple note.

2010 macbook pro 15". Charger green, indicator lights all green, will not power on. Shut off suddenly over a year ago, and I have not used it since. I bought it used from a trusted seller. It is a mystery.

This is might help:

I had given up on finding a solution until i found your video. It's just a miracle!!!    

- macbook pro mid 2010

- reason for the problem: i believe because i removed the battery connection from the motherboard without shut down the system.
