Windows 10: My Laptop's Battery is showing "Plugged In" and my Charging Light is On but it stops at...

When my Laptop's stop charging, my speakers also stops working. Now, If I remove my charger, the laptop shuts down. Sometimes the laptop stops charging at 32%, sometimes at 50%. It starts with the speaker stops working and then, the charging stops and If I unplug the charger, it simply shuts down. I am able to charge my laptop if it's powered off. And the laptop works fine without plugging the charger. My Battery health is 52 % and the Windows Diagnostic Test is telling me that the Battery is reach the end of its life cycle. Is my battery is faulty or is my charger's also a culprit ?

Plugged in but battery does not charge

If the laptop works without the battery then charger is functioning correctly. Take a cloth with a bit of rubbing alcohol on it (or some on-the-go alcohol swabs), and clean the metal contacts that connect your battery to your laptop.

Make sure to install all Windows important updates.

Install latest versions of your laptop device drivers you can download the latest device drivers from the device manufacturer or from your laptop manufacturer website.


Step 1

1. Shutdown your laptop.

2. Remove the battery.

3. Connect the AC power adapter to your laptop.

4. Power on the laptop

5. Open the Device Manager by typing Devmgmt.msc into Start Menu or from Control Panel.

6. Under the Batteries category, right-click all of the Microsoft ACPI Compliant Control Method Battery listings, and select Uninstall (it’s ok if you only have 1).





7. Shutdown the laptop.

8. Insert the battery.

9. Power on the laptop.

If above suggestions wont resolve the battery charge issue then follow below steps.




Step 2

1. Shutdown the laptop.

2. Remove the battery.

3. Start the laptop with only AC adapter connected to laptop.

4. When you login to Windows OS connect the battery while Windows OS working.

Hopefully one of the above suggestions will help you resolve the battery not charging problem. If battery still doesn't charge, you may need to replace your battery.

 

Battery plugged in but not charging.

A further update on "Plugged in not charging" (PI,NC). A few days ago I deliberately discharged the laptop battery and on plugging the charger back in the battery was not charging. This time, because I had read the suggestion somewhere, I just disabled the Microsoft AC Adapter and the Microsoft ACPI-Compliant Control Method Battery in Device Manager. I then enabled them and found the battery was now charging.
Today, as a further test, I again let the battery discharge, down to 6%. When I switch the charger back on I found the battery icon displaying the "PI,NC" message when I hovered the cursor over it. I went into Device manager and disabled both the Adapter and the ACPI. Immediately a message appeared on the screen to the effect that hardware changes had been detected and the laptop would restart, which it did. The battery icon had disappeared, as expected, but the battery charging light was on. I went into Device Manager and both Adapter and ACPI were still both showing Disabled-Code 22. The battery charging light was still on however. I enabled both Adapter and ACPI and the battery icon re-appeared, again as expected. The battery was now showing 11% charge, so I conclude, though I do not understand how, that the battery was still charging in spite of having both Adapter and ACPI disabled. As I write I have now disabled the Adapter only in Device Manager but the battery is still charging. I have now enabled the Adapter and disabled the ACPI. As the battery icon has gone off screen I will wait a few minutes before I enable it and check the degree of battery charge. The battery charging light is still on I should add.
Having now enabled the ACPI I have found the amount of charge on the battery has increased quite a bit.
It seems to me that, as far as my second hand Dell E5420 Latitude laptop is concerned, it is necessary to disable the Adapter and/or ACPI in Device Manager to kick the battery charging process into action. I really would like to know why this is and, more importantly, what purpose the Adapter and ACPI in Device Manager serve other than to display the battery icon and start the charging process when disabled.

 

Battery plugged in but not charging.

All laptops will say connected but not charging when the battery reaches 100%. There is no trickle charge to keep the battery topped up, it would damage a Li-Ion battery to do so.

It is normal behaviour on a Dell for the battery light to go out when the battery is fully charged. Some other brands I own keep the light on at all times a charger is connected, but change the colour to indicate the state of charge. Usually it's amber to indicate charging, changing to green or white when fully charged. The charging light turning off is Dell's way to tell you it's fully charged. Unfortunately this is indistinguishable from the case of no charger being connected, or an unrecognised charger being used.


Interestingly, while I was waiting for the genuine article to be delivered I found that a spare universal charger I had (the sort suppled with a selection of adapter tips for the lead) would sometimes be accepted by the Dell. I'd plug it in a few times until the battery light lit up then leave it to charge normally. I'd see the same effect in the F2 bios screen, about one time in four when plugging it in the bios would show a '90W adapter' instead of 'unrecognised'. So it looks like the center pin may not be the only way a Dell decides if a charger is acceptable. This may explain why your charger sometimes works. My universal charger certainly had no 'third wire' on the lead's own plug. The Dell adapter's third pin had nothing it could be connected to, but still it would charge sometimes.

I still suspect there's a fault or a broken third wire in your Dell charger.
