Defective power button (not working)
I have a MacBook Pro 13" Early 2011 2.3 GHz intel Core i5.
To start the mbp I have to take back cover off and remove battery connector for a couple of seconds.
After reconnecting battery and case back on, will not start with power switch. As soon as I plug mag safe in computer boots up normally (no switch or keys are pressed).
Computer operates normally in this mode, battery charges and the power can be disconnected and battery will run computer. Power can be reconnected any time to charge battery.
Problem occurs when mac is shut down, it will not restart unless I go through process described above.
i believe it is the power button/switch, I am not sure if it is shorted or open.
I have removed the button and cant see anything obvious.
The biggest issue with this is not being able to start with the battery alone, so as a portable it is not usable.
If I keep it plugged in it will go to sleep and wake up when a key is pressed, so makes a good desktop
Any suggestions would be welcome.

A few times on an old mbp the power button seems to have stuck in the down position and would not function. Using one (1) drop of super glue (placed carefully so that it cannot run down the side of the button) I have attached a small vertical peg to the center of the button. After plenty of drying time I have pulled slowly, gently directly up using fingers or a small pair of pliers. The button has lifted into place. Then it has operated normally until the problem recurs. The peg can be snapped off. The rough super glue surface of the button has been no problem. I was reluctant to try this but it worked out well.
