Q: mac book air doesn't turn on

I Have a 13 inch 2011 Mac Book Air and it has this strange behavior: When I use the mac book air for a while and I shut it down and I try to turn it on again it doesn turn on when I press the power button.  It doesn't emit any sound or light. Nothing.

If I wait a day or so, it turns on again as it nothing happened. It is a really strange and anoying problem. I never spilled water on it.

A few things I tried and did not work:

• Plugin the power adapter doesn't work, is not a battery problem as it has more than 90%
• Press harder the power button doesn't help
• It lets me reset the smc but it doesn't help with the problem
• Reset NVRAM is not possible as it doesn't turn on
• Reinstall OS X didn't work either (OS X Version is El Capitan)
