    I have a Mid-2009 MacBook Pro 17" that works great. But when I turn it on or resume it from sleep, it shuts down immediately.

    I press the power button, it turns on and shows the apple logo - then shuts down like someone pulled the power. I do this about 4 or 5 times before it actually fully turns on.

    Sometimes a PRAM reset helps it in the second try, but I don't want to do this every single time I boot up.

    Any ideas?

    I did the disk repair and apple diagnostics passed.

    After it gets into OSX, its perfect with no problems. But when I sleep it or shut down, it won't turn on again. Even going SMC,PRAM resets doesn't turn it on all the time.

    Has anyone experienced this?
