I was getting a message saying my battery wasn't charging although I had it plugged in. I thought it might be a floor so I just ignored it. However, it became a nuisance when turning it on after hours of charging it was giving me the same message. I read the fix on this but mine is a 1545 model. Furthermore, now, when I tried to turn it back on again. It came on for a couple of minutes then went dead.
Does the system power on and stay on with the adapter connected?
Are you using an original Dell OEM Adapter? When you plug in the adapter to the system, does the adapter stay firm or does it fall off easily? Is the adapter frayed? Is there any damage on the system? Could you test with another power adapter if possible?
Restart the system and press f2 key to enter BIOS - check the adapter status in BIOS with and without the adapter plugged in. Also, wiggle the adapter cable at the end and see if the status changes in BIOS at any point. Check the battery health in BIOS (if applicable).
Restart the system and press f12 key on startup - choose diagnostics. Let it run the diags and if you encounter any errors - make a note of the complete error and report the same to us. These are onboard diagnostics and they might possible pick some error if the hardware is not functional.
Test another adapter and battery and check. If the adapter fits in loose, then replace the dc port - this is the part you need - http://bit.ly/2hQmNjo
If nothing works, then you might need to replace the motherboard.

My personal suggestion is that, if the motherboard is being replaced, then you could invest your money on a new machine than to repair this system. However, that is your discretion.
