This question already has an answer here:

After I upgraded Windows 7 to Windows 10 in my Samsung laptop, the AC charging stop at 80% and show "plugged in, not charging".

Then I downgraded back to Windows 7, problem still exists.

I have tried :

  1. Shut down
  2. Remove battery
  3. Boot up on AC power
  4. Uninstall the ACPI-Compliant Control Method Battery driver
  5. Shut down
  6. Reinsert battery
  7. Reboot

Still cannot fix the problem. I am wondering whether it is a configuration problem?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.


Check your BIOS/UFI settings. There is an option to extend the life of your battery by not charging it all the way back to 100%. Additionally, if you have the Samsung Settings program installed, you may also be able to toggle it in there as well.
