Laptop plugged in not charging

[HolmesGuo]

I noticed my laptop was not charging when plugged in after a recent window update at the end of November. It says 'plugged in, not charging'. I plugged it in after that and it started charging again for a few minutes and then it went back to the 'plugged in, not charging' status. 

Also, when I was playing games I can see the CPU utilization drops from 80% to 17% every 10 or 15 seconds and last for 3 to 5 second, which causes the FPS in the game to drop at the same time, it never happened before, not sure it is related to the battery issue/windows update or not.

A few things I tried:

1. "Device Manager"--and uninstall  "Microsoft ACPI Compliant Control Method Battery"  and restarted, still shows "plugged in not charging” after a few minutes 

2.Update the BIOS from hp.com, not working

3.Got all the new updates recently

Any clue as to what is causing this? It seems like it's some kind of software issue. If not, maybe I need a new power adapter? If so, how can I get the right one for my model?

Thank you for posting your query, I'll be more than glad to help you out 🙂

I see that your experiencing plugged in not charging issue, I appreciate your efforts to try and resolve the issue.

Let's try this steps:

Run hardware diagnostics test on battery and Charger:

Use the following steps to open the Component Tests menu.

1. Hold the power button for at least five seconds to turn off the computer.
2. Turn on the computer and immediately press Esc repeatedly, about once every second. When the menu appears, press the F2 key.
3. On the main menu, click Component Tests.
4. The Component Tests menu displays. Your Component Tests menu might be different, depending on the components installed on your computer.
5. To run both tests simultaneously, in the Component Tests menu, click Power Source, and then click Run once. Each component can also be tested individually.

AC Adapter Test

The AC Adapter test provides an interactive test to determine if the AC power adapter is functioning properly. A good battery is required for this test. Before running the AC Adapter Test, HP recommends verifying that your computer can receive power by connecting a known working AC adapter.

Follow these steps to perform the AC Adapter Test.

• In the Component Tests menu, click Power, and then click an AC Adapter Test.
• Click Run once.
• The AC Adapter Test begins.
• When the test is complete, the results are displayed on the screen.

Battery Test:

Follow these steps to perform the Battery Test:

1. In the Component Tests menu, click Power, and then click Battery.
2. Click Run once. The Battery Test begins.
3. When the battery test is complete, the results are displayed on the screen. For additional battery information, click Battery Details.

If the test passes, continue with these steps:

1. Go to Start, search for Device Manager, and open this result.

2. Expand batteries.

3. Right-click on the ACPI option (usually the 2nd option) and select delete or uninstall. Follow the prompts.

4. Shut down the computer. 

5. Disconnect the charger.

6. Remove the battery.

7. Hold down the power button for 1 minute.

8. Insert the battery only.

9. Attempt to turn the battery on.

If possible, try an alternate charger.

Thanks for all the help, I tried everything in your reply, both AC adapter test and Battery test passed, however, I do have an unremovable battery so I held down the power button for 1 minute without the battery removed.

I also bought a new charger and it still says "plugged in, not charging".

Any other things I should try? I noticed a lot of Windows users having the same problems these days after the windows update, not sure how they fixed it.
