Aspire S7-392 does not turn on, both LEDs does not turn on even with power adapter

I have Aspire S7-392 for almost three years. I charged the laptop for few hours and then switched off the power. After few hours tried to turn it on and the laptop won't start. I put the AC adapter to charge again but see that LEDs do not turn on with AC adapter. Checked the adapter and it seems to be giving correct power output. After searching other threads tried the following:

battery reset for 4 sec

Tightening all of the screws on the back

battery reset with power button for 10 sec

 

None of these seem to work. Any suggestions? Will replacing battery help in this situation?

    i don't think a battery replace would fix it, since both LEDs don't turn ON.

    The only thing i would try is to disconnect the battery and connect the AC adapter and check if at least one LED turns ON.

    Thanks IronFly I tried as you suggested. However LED does not turn on even with battery disconnected. Is it motherboard issue?

    1) Dead AC adapter or low amperage but you already tested

    2) hardware issue on motherboard
