I can't turn on my switch

Marcos, we'll need more information in order to help. The more details you can give us, the better your help will be.

Does it give any indications of life under any circumstances? Can you see anything at all on the screen?

Is there any difference between running off the batteries vs. the charger vs. the dock?

Is there something wrong with the power button?

Are there any sounds at any point?

These are the sorts of questions that will give us an idea of what direction to point you in so you can get your Switch running again.
