Not turning on after crash.

Essentially my MacBook Pro crashed while I was opening QuickTime not too long ago and ever since I have not been able to turn it back on.

The only signs of life are when the MagSafe connector is connected with shows green and then allows me to push the battery indicator button. If I press the button immediately after plugging in the adapter it will rapidly blink the first LED and then any presses afterwards will flash all eight LED’s.

Other than that nothing else appears to work. I’ve taken apart the entire computer and there aren’t any obvious signs of damage.

Thank you in advance to any suggestions; I’m willing to try just about anything!

The flashing battery tester LED’s is telling me your battery is worn-out! You’ll need to install a new one. Here’s the needed part MacBook Pro 15" Unibody (Early 2011-Mid 2012) Battery and the IFIXIT guide to put it it Sostituzione batteria MacBook Pro 15" Unibody versione inizio 2011

Unfortunately, I don't think that's going to solve the problem. I was operating the computer on battery power when the crash happened, and it had roughly 100 cycles on it.


What is the MagSafe charger LED, Amber or Green?


Shouldn't I be able to start it or see at least some kind of life with just the power adapter? Also, it doesn't exactly explain the seemingly random crash... Although I do recall possibly having read something about the battery being necessary to charge up a capacitor on the logic board.
