First thing to check is in setup (F2 at powerup).  Make sure the adapter is listed along with its power rating.  If it is not, and you've changed the adapter to no effect, the next thing to change is the DC jack: [URL] If the adapter and battery are recognized, but the battery will still not charge -- or replacing the DC jack doesn't get the adapter recognized, the charge circuit has failed and the mainboard will need replacement.  How much this will cost depends on the CPU you have in the system -- but it will be at least a few hundred dollars just for the part, before labor.  
Hello, Recently my Dell XPS 9360 just decided to stop charging. I got a new charger (an OEM one) and replaced the battery (non-OEM) and neither worked. I checked in the BIOS and I do not have a custom profile set. I assume it is one of the smaller components between the charger and the battery that I doubt I can fix. Is there anything else I can try? I am outside my warranty so I would have to pay $40 - $60 just for Dell to tell me what is wrong, much less to pay for the repair. I am wondering if anyone knows generally how much this fix would cost?
