Hi, after pressing the power button all keys, wifi , volume, power button is lighting up and again they are getting stopped. This is happening repeatedly with 1to 3 seconds gap. 

 

Sometimes i could open the home screen and desktop, post opening withing seconds above blinking sequence is getting started.

 

Some times with blue screen i could see APC index mismatch error and blinking sequence is getting started.

 

I have tried removing battery and starting with charger, trued bios reset with USB. But within seconds blinking sequence is getting staryed.
