laptop - plugged in, not charging + ONLY runs on AC power

Laptop Model: Acer Aspire V5-473P

Laptop Age: 22 months

OS: Windows 10 (Upgraded 6 months ago)

Problem Occurred: 5 months ago.

Problem Description:

• Battery icon suddenly started showing "plugged in, not charging" at 80%. Since then, laptop ONLY turns on with AC power (doesn't matter battery is plugged in or not), when the AC power is removed, laptop stops running immediately(no regular shutdown process, because battery is not supporting it at all).




• Battery started being depleted since then, after 5 months, now it is 0%, and still showing "plugged in, not charging", and laptop still only runs on AC power.




• The led indicator for battery is always on when AC power is connected (its perfectly stable, not blinking).




• From the battery report, battery seems OK to me (Please notice that "Full charge capacity" is still a healthy amount)

What I tried:

Method 1:

1. Disconnected AC power


2. Shut down laptop


3. Removed battery


4. Connected AC power


5. Started laptop


6. Opened "Device Manager"


7. Uninstalled "Microsoft ACPI Compliant Control Method Battery" (all occurrences)


8. Shutdown


9. Disconnected AC power, inserted battery


10. Connected AC power, started laptop

Result: Did not work.

Method 2:

1. Removed the power adapter and Battery.


2. Pressed and kept holding the power button for 40 seconds.


3. Connected the power adapter without fixing battery.


4. Power on the laptop .


5. After logon to the windows, Shut down the laptop.


6. Fixed the battery and connected the power adapter, then powered on the laptop again.

Result: Did not work.

Is it a battery issue or a charging circuit problem? What should I do now?
