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?
