Windows 10: My battery isn't detecting, it's not the charger it's not the charging port, it's plugged...

I got this laptop before February it was refurbished, I plugged it in and waited 5 hours and at first it was charging very fast it was almost halfway charged and when I go to turn it on it suddenly said low battery and then I looked and seen that there was no battery icon at the bottom of my screen, the laptop is fully plugged in and the light is flashing red I tried a different charger meant for the same laptop and that didn't work. I went to a specialist and he replaced my charging port I'm plugging it in now and it's still doing the same thing. Telling me low battery in the same flashing li

Plugged in, not charging


There are 3 points of failure for a laptop that does not charge (And has been determined to be a hardware problem and NOT a software/OS problem). OS problems can be tested as mentioned above.

• Dying battery (end of recharge cycle limit) as DustSailor and bro67 have mentioned.
• Defective/dead charger/power supply
• Broken DC In port (very common)

Sometimes in the case of a broken DC In port you can wiggle the power jack in the port and see it starts to charge and then goes back to "Plugged In Not Charging" when you let go. But not always.

Sometimes with the Charger/Power Supply it is only the jack that is defective.

First order of business is to borrow a Charger/Power Supply (be sure it has the same voltage IN as yours) and test it to see if it will charge the battery.

The rest is replacing parts until you get to the offending one.
The Charger/Power Supply is cheapest to replace first.
Then the Battery
Then to the shop to see if the DC In port can/should be replaced.

 

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.





Step 3

Reset the System Management Controller. Use one of these methods to reset the SMC, which controls battery management, battery status light.

1. Shut down the computer and disconnect the power cord.

2. Remove the battery.

3. Press and hold the power button for ten seconds.

4. Reattach the battery and AC power adapter, then start up the laptop.


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.
