I purchased Depp Inspiron 3520 laptop last september 2012 , Until december it works fine , but few months back when laptop was connected to AC power with Ac adapter when I pressed start button nothing happens & computer is not start up but randomly sometimes without any problem it started but now when I press power button nothing happens.
I tried by disconnecting battery pack , pressing power button for two minutes & shorting AC adapter two pins & then reconnecting battery pack & AC adapter but nothing happened & computer did not started up.
Please help me to solve this problem.
