Laptop 7506 2 in 1 does not turn on

I bought the laptop a week ago. It worked for a few day. Now it does not start up. The charger displays a green led light and is working (even on another laptop). 

The light on the side of the laptop that indicates your AC Adapter is charging the PC also doesn't light up. I've tried to press the ON button for 30 seconds. Does not work. What to do?
