I bought Asus Vivobook S 14 S406UA- BM204T in 23.12.2018 and it's not working today 27.12.2018 

When I press the power button nothing happens, there is a light flickers on power button and charging slot of laptop.

The battery is non-removable, so I can't try to unplug the battery.

I tried holding the power button for 15, 30, 45 and 60 seconds without being plugged in and nothing happened.

Pls help
