Hi  @krs1 ,
First you need to do a simple step called power drain. 
* Turn off the computer 
* Unplug the charger and flip the computer upside down.
* You will find a tiny pinhole with a battery icon. put a paper clip or pin into that and hold it for 30 to 40 sec.
After that you need to check that are you able to get into the BIOS screen or not. For that you need to turn on the computer and immediately tap on F2 and check you are able to see anything on the screen.
If you are able to see a blue page tap F9 and hit ENTER after that tap F10 and hit ENTER. 

if this does not work try with different wall socket.

Try this and post your results.
