Hp envy 15-as050sa doesn't turn on

It worked perfectly fine before. But in the middle of watching YouTube it turned off. It was on the charger, but the charger light wasn't on. Even when I borrowed a hp envy charger from my brother, still didn't light up. I tried turning it on, but failed to do so as it showed absolutely no signs of life. Pls help this is the only pc I have, if I need to send it in for repair with no other way, I will do it
