    Not sure if its your power button..

    If the power button had been stuck in, the computer would have turned off earlier. (If I hold my down it forces shut down)

    Can you not book an appointment at the genius bar?

    Hope you've got APP.

    If your good with electronics you could take apart the machine and look for a test patch to short, on the logicboard which would allow an engineer to fire up the Mac.

    However, there's no way to tell what marking it might have near it other than a couple of square brackets.. kinda like: [• •]

    A SMU reset is worth a try.

    Check out this apple document:

    Obviously, you'll have to ignore the part about what to try before reseting the SMU because you can't power the machine on but give the reset a shot, it might work.
    Good Luck

    I know it's been like a year, but was this ever resolved? I am having a similar issue and Apple told me they want to send it away for 1250 because other things "might" have been damaged. I am so sure that everything else is fine, it was working great until the power cord accidentally got knocked out and it died. Did you end up getting it fixed?

    disconnect power... undo the casing... disconnect the battery for a few seconds... then connect the battery back again... then insert the power cable... white light should blink on the front right, then mac should boot into life. havn't got a resolve to fix the button, but at least this gets the thing back to life. repeat process if powers down again..

    same to me Gutted

    this is my 3rd MBP not learnt my lesson yet.
    last night , Just down the mac as normal and closed the lid, This morning , opened , press the button. NOTHING , went on all forums, Tried everything, landed up going to mac, the set it saying it was the power button. Scared the hell out of me when told it would cost a fortune. as the whole top needed to be replaced, Can the button just be replaced, When macs go wrong, its stupidly expensive, And they do often.
    My Toshiba 8 years before I sold it.

    My other two MBPs , logic boards and screens. where do apple get their parts from?
    So this power button. on 2011 BMP 15 inch? :(

    Power button turns MacBook Pro off, but not back on.

    Any resolution? My power button powers my mac off but not back on. I have to replace the battery to get it to power on again.

    I found a fix!

    I have the late 2008 aluminum unibody Macbook. My power key just stopped working after I wiped it down with a damp cloth. Took it to Apple and they told me to buy a brand new laptop, mine was beyond repair. I stumbled across this youtube video:

    1. Jump starting laptop -

    I used a paperclip to touch the roughly the 5th to the 29th prong and my laptop started up. Everything functions properly now except for the top row of my keyboard and the right shift key. If you have a 2010 macbook or newer, take it to a repair store to get the keyboard replaced. The reason you can't just replace the power button is that it's attached to the whole keyboard system and things get fried together.

    If this does not solve your problems, your issue is with the logic board which is a much bigger issue.
