Windows 10: PC plugged in but Battery not charging

According to this message, my battery isn't at 100% - it's plugged in but not charging. What do I need to do please?






PS It's not a Windows Performance failure but I can't think of another forum that I should use. Perhaps I should 'park it' in Microsoft Garage - the new Category on the list - but I haven't a clue what that is, not having seen any announcement about it.

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.

Thought I would give an update on plugged in - not charging problem on my Dell Laptop E5420.
For some days now while using this laptop I have left it plugged into the AC Adapter with the battery showing 100% charge. This morning, on opening up, I noticed the battery was showing 92%. On inspection I found I had disconnected the AC Adapter in error the previous evening, so I reconnected it. Immediately the battery started to charge.
I switched the laptop off and back on pressing key F2 to find that, although charging the battery the AC Adapter was still shown as unknown. I switched the laptop off again and this time I pressed key F12, after switching on, to get into diagnostics. I found that, although the battery was again charging, the 130 watt Adapter power was still shown as 1 watt.
I am mentioning all this just to demonstrate how a Dell Adapter can be working perfectly well even when not recognised by the PC it is powering. I am hoping the plugged in-not charging message is a thing of the past, not to be repeated, but I won't hold my breath.

 

Battery plugged in but not charging.

Hello Bree & Callender, This morning I fiddled around trying to get the charger to work in the boot process by pressing F2 and the waiting for 10 minutes or so before continuing to log on. The amount of battery charge was still 5% which it was prior to all that. I did this because it was a suggestion from Dell as a possible solution. I then considered updating the BIOS as this is another Dell suggestion to overcome the battery not charging problem.

I then had another look at the adapter to confirm its output which is 130 Watts. Anyway, after an hour or so seemingly getting nowhere I noticed that the battery signal to the left ot the keyboard had lit up. I immediiatly checked the battery icon on the screen and found it was now showing that it was charging and 1 hour 31 minutes to full charge. I decided to leave everything as it was for a couple of hours after which time it was showing 100% charge on the battery.

Later on however I noticed that, although still showing 100% charge, the battery “connected but not charging” message was back. Needless to say I am even more flummoxed. I read all the links you posted Bree and found them very interesting. Nevertheless I am now wondering why the chargeing process had burst into and then died again. Someone, somewhere knows what’s happening I am sure.
