Won't turn on

Few days ago I left my MacBook aid 2013 model at home. Charge was around 80%, when I came back in a few hours it wouldn't power on.. Weird maybe battery died, plugged it in, press the power button, nothing...

Looked up problem online. Did all the command+p+r+ option and other similar option, nothing. No fan, no power. Nada.

Read somewhere that if there has been a power failure something can get fried? I'm travelling now and currently in Mexico, I asked and there was a power outage. What could this be?

I'm going 7 hours to a different city now where there is an authorized repair Center.

Locals thought it could be Cuz of humidity and salt, I've been in coastal cities last 1.5 years.

Any idea what it could be guys? Anyone else's max just doesn't turn on? Virus?
