My laptop doesn't turn on

I've a similar model of laptop

Mine says UX582Z

I was using my laptop when it just turn off with de 50% in battery

After 30 min it just started again

I keep using it and I used all the battery

After that I connected the charger but it doesn't work

I check the voltage in the charger and it's normal

I open the laptop and the board has the 20V and the 3V and 5V in all the components that they need

I took all the main board out and I connected the charger to check the V again and it's normal

But the led that turns on when the charger is plug doesn't turn on

And it still no charging

And I also check the battery and has V
