Windows 10: Flashing battery icon, not charging when plugged in, slow computer

I have an Acer Aspire 5, and it recently began running very slowly. No internet issues, installed Windows update, cleaned up browser, cookies, start up apps, ran diagnostics, etc. I then called Acer support and they recommended doing a system reset. I did that - twice, once selecting the "retain personal files" and the second time wiped clean, windows reinstalled.


There's been no change. Still reallly slow and the battery is flashing, no charge. The Acer rep thought I might be better off downloading windows from a different computer to a flash drive using windows media creation tools and reinstalling that version. Aside from that, I'd need to send my computer back to them and of course, it will be awhile before they get it back to me...


Before I do that, does anyone have a suggestion? Thanks!

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.

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.

 

My Computer is Plugged in but not Charging

My laptop computer is plugged in but not charging. The power supply will maintain the charge level (%), but not add to it. Removing and reinserting the battery allows the power supply to add to the % charge to 100%.

Steps performed:

• Turning the computer off and restarting it returns the computer to the Plugged in, Not Charging state.
  
• Removing the battery again allows one complete charge, after which the laptop would no longer charge again.
  
• I have used more than one power supply with the same condition.
  

To resolve the issue, I remove the battery, obtain a complete charge, and maintain this charge by always keeping the power supply plugged in.

What is the root of the problem?

 

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.
