It stopped working and it doesn’t turn on again… you guys can see the lights of the adapter isn’t turning on as well.
What you guys think it could be?

One thing for fure is that it is not the adapter.

    If you don't know what a bios battery is😁 I suggest that you take your laptop either to Acer Tech Support or an experienced technician in your area so that they can fix the problem that you have. Fixing your laptop is not a matter of buying components or resetting it, your laptop has an internal circuitry problem that is stopping your laptop from booting, and it needs an experienced technician to diagnose your laptop and fix the laptop so that it boots and turns on.

    First try to do a Hard Reset, by taking the main battery out, then disconnect the bios battery and shot its +&- pins at the mobo plug, then take the ram out, leave the laptop like that for 15min, and the reconnect every component back and try to reboot.

    If that doesn't work then check the adaptor if its off or faulty, check the DC_IN port and the adaptor plug if both are not shortening the adaptor out, as a charger adaptor automatically turns off at its safety switch if there is a short at its plug or at the laptops DC_IN port or the laptop itself. If that is not the problem then its your laptops main power rail that has a capacitor or a mosat burned or shorted, so follow the mobo rail and circuitries circled below which needs a multimeter and an experienced technician to do.
