My MacBook air does not turn on?

My macbook air 11" Mid 2012 suddenly does not turn on anymore.

Tried pressing the power button on for 10 secs, released and tried again - no luck

Tried resetting SMC, pressed and held Shift + Control+ Option+ Power buttons. Released the keys at the same time. Then tried turning on the Mac.

Tried resetting NVRAM.

Do not hear fan or any sounds, seem completely dead. When I connect the power adapter the light on the magsafe turns green, but still no sound or power or boot.

Looking for suggestions and next steps.

Did you get your system wet at some point (spill or sat it down on a wet surface)?

из

Not that I can think of, don't see any wet areas in the bottom or top. How do I verify that there was no wet areas.

из

You could open the bottom cover and look for red dots if you see them it was wet at some point.

Does this model have a battery test button?

I did not see a battery test button. I was trying to get the bottom out but was not sure which IfIxit bit to use ?, T3 ?

Assuming you didn't get your system wet it doesn't sound good here. Most likely the CPU has crapped out.

I would visit an Apple store to see what they say, at least get a free estimate on what the costs will be.
