I have tried unplugging the adapter from the machine and plugging it back in, and restarting the machine, with no success.
Any ideas? Thanks.
Solved! Go to Solution.
Have you tried checking inside the BIOS of the computer if the AC Adapter and the Battery is working fine? Also try to run some diagnostics to the computer.
This sounds like a battery calibration issue. Try running the battery down until your laptop shuts off, then plug in the AC adapter and see if it charges to 100%.
Hi Kevin B,
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.
Try running out the battery as per the other users response. Once done, connect the power adapter and check if it charges the battery or not.
If the adapter port is loose, then the adapter would not be recognized sometimes and the battery hence will not charge, then the dc port needs to be replaced - you would need this part - http://bit.ly/2epY7Yt
Also, please click my DELL-username and write me a private conversation with the service tag and your Name for case records.
Let us know if you have any other queries.
