While I was doing some basic file management in the Finder, my MacBook Pro (mid 2012) suddenly went black. It wouldn’t turn on, even after long-pressing the power button or resetting the SMC (System Management Controller). The SMC reset caused the battery indicator light to go from green to red, but even after ten minutes of supposed charging it is not responding to the power button. My symptoms are similar to this and this post, but I have not spilled any liquid on the computer (quite the contrary; it has been stored for over a week on a dry, high shelf), and the laptop does not react to the power button even with the power cord attached.
Do I have any other options but taking the Mac to a repair shop?
