Tablet not charging, light turns on

I'm not sure which version of Nextbook this is, but it's a tablet and a keyboard. My father gave it to me, because it wasn't working and he assumes because I'm younger I'll know how to fix it; I do not.

I plug it in, and there's a light next to a white battery icon on the side of the tablet, where the charging port, headphones, etc is, that DOES light up, but the screen doesn't do anything. I assume the light that turns on is the same one that signifies when it is dying or low battery.

It's plugged in currently, and I'm gonna leave it to charge overnight, but if the screen isn't turning on, does anyone know why that may be?
