DELL INSPIRON 15 3000 SERIES POWER PROBLEM

Good day i have a DELL INSPIRON 15 3000 SERIES.. I started using it from FEBRUARY 2016... I have no problem using it until this June 12 2016.. It just wont turn on... When the adapter is plugged the charging LED opens but later the light will disappear.. I already tried the 30 seconds power press without the battery and the adapter to release the stock power.. But it still doesn't work,,, I'm confused because why do the CHARGING LIGHT TURNED ON WHEN I PUT THE BATTERY ON AND PUT THE CHARGER IN..?? any help please or suggestions... please and thanks
