I've owned my Dell XPS 15 L502x for just over a year (thus, I am out of my warranty period) and recently it has stopped being able to charge. I am completely tethered to the AC power adapter to use it as I'm on 0% battery and have an inability to charge it.As well as my inability to charge the laptop, I have noticed the following things:
Hey, I'd got the same problem today, and already fixed it.
For me the problem started because I use my laptop only plugged without the battery. I don't know if this would fix it each time but you can try the following.
In the "Dell Battery Meter" options you need to disable the battery charge and then enable it again, you can reach those options 2 ways.
1.- Right click on Battery icon (task bar). In the context menu hit Dell Battery Meter
2.- Open Start Menu and type Battery, select "Change battery config.", in the left panel hit Dell Battery Meter
So disable battery charge, enable it again, and see if it gets fixed.
I repeat, this worked for me, i'm not sure it would work 100% of the times
