when i turn my macbook air off it won´t turn on again. How do I reset it?

I have a Mac book air, after working on it for a while I will turn it off and then try to turn it on again and it won´t start.

If I wait a while, like an hour, it will come back by itself.

This mal funtion is recurrent. I´ve taken it to the shop for repair and the mal function does not happen to them when they are doing try outs.

How do I reset it?
