I got samsung book 4 360 4 months ago i was using it normally and the screen went black but powe was on i tried to open it but when i pressed the power button it restarted again and then the power went off and i am not able to power on the laptop 

My battery was fully charged and i can see the green and red led indicator while connecting to the charger 

I have been trying to drain the battery by charging my phone through the charging port
