THE LED LIGHT OF MY DELL INSPIRON 5594 MEANT FOR INDICATING WHETHER IT'S CHARGING OR NOT IS NOT WORKING EFFECTIVELY..

IT USED TO BLINK ONCE WHEN PLUGGED IN, THEN WITH A GAP, USED TO BE ON CONTINUOUSLY.

BUT NOW, IT JUST BLINKS, THEN TURNS OFF ALTHOUGH ON MY SCREEN, IT IS SHOWING THAT MY LAPTOP IS CHARGING...

IS IT USUAL OR IS IT THE PATTERN OR IT IS BECAUSE MY LAPTOP IS ON?
