Acer enduro not charging randomly and now It won't turn on the light for charging.

That could be issues with either the DC port and cable that connects to the mobo or its a mosat in the power charging stage of your laptop which needs to be diagnosed by a technician, you can't fix these internal circuitry mosat, capacitor problems as you need the proper tools, and also and if this problem is within these mosats that governs power to the gpu or cpu then this could be critical as your laptops mobo might need replacing, as a cpu or gpu can't be replaced if its shorted out and a mosat allowed to much current into either the cpu or gpu. The only thing that you can change, and fix is if the DC cable/plug and port is faulty, that you can change for a new one, if the problem is there?

Then its the DC port at the side of the laptop, get a fine pointed picking tool and bend the outside negative pins inward so that the charger pug makes contact with the negative part of the charger plug when plugged into the DC port, or change the DC port/cable/plug for a new one if its damaged beyond repair, its an easy job to do.
