Dell Inspiron not turning on

Hello everyone,

I have a Dell Inspiron from August 2015 and today it wasn’t turning on. I noticed once I turned it on with the AC adapter still plugged in, my battery LED light would blink once with my keyboards backlight and then turn off. I tried some of the trouble shootings from online such as draining the residual battery after disconnecting the battery and AC adapter, but when I plug in my AC adapter to turn it on without the battery it doesn’t turn on. During this phase I also don’t get a white LED to light up either, does anyone know how to help?
