Dell Inspiron 15 3537 laptop not starting up [Closed]

I have dell Inspiron 15 3537 my laptop stopped starting before few days all of sudden I tried the flea-power drain and everything it didnt start. After one week when I checked again it started normally. Now after a month of regular use.I didnt use it for just one day it stopped working again.Same issue the battery charging light turn on when adapter is attached and for now thats just the sign of laptop neither fan turns or nor any pre boot device check takes place. May I knw whats wrong with it?????

Thank You
