MacBook Pro 2016 does not turn on I have a MacBook Pro 2016 with a touch bar, and without prior warning it is now refusing to turn on. Pressing the Touch ID button does nothing: no chime, no screen activity, no computer noise, no Caps Lock LED. Resetting the SMC has no effect.

Is there any kind of diagnosis I can perform before bringing it to the Apple Store? Is there some secret key combination that will make it tell me where it's failing? Can I somehow connect it to a second computer and use that to perform a diagnosis?  

Guides freely available through Google don't say very much beyond these steps that I've already taken.

I guess my real question is:


  What will Apple itself do before starting to dissemble it? Can I do that myself?
If you press the power button and nothing happens, there's no special or secret combination of keystrokes that will get you into diagnostic mode,

Given that it is so new (and still under warranty), you want an exchange, not a repair.  This is way too new for you to be having this type of difficulty.

As to your question, "what will Apple do?"  They will look at it, press the power button, check your charger and then then they will give you another machine.  They won't attempt to repair it.
