Had my XPS since January 2016 and all of a sudden my power adapter has stopped charging the battery. I can still use it when plugged in but it instantly dies when it is unplugged.
Is there any way to fix this?
It appears the battery has failed, and most likely needs to be replace with a new one. Just to be sure, I'd suggest you check status of the battery health and AC adapter in BIOS. If adapter isn't detected in BIOS, the system will continue to received power but will not charge the battery. Please follow steps below:
1. Power off system.
2. Power on system, quickly start tapping F2 key continuously. You should be in the BIOS.
In the BIOS, the battery health should be listed under main screen or battery information. The battery should say Excellent. The adapter should say the adapter type, if it says 'Unknown' or 'None', then it's a issue with the adapter, and most likely needs to replace with a Dell genuine adapter that suitable for the system. Note: Wiggle the adapter's end while checking it in the BIOS.
I've checked in the BIOS and the battery health is excellent.
This is the third major issue I've had with Dell products in the past year and it's just getting infuriating.
It appears you have faulty adapter. Is the adapter the original that came with the computer or some type third party adapter ? Does the computer sits on a docking station ? If yes, try the troubleshooting steps in link below:
