The Battery in My Aspire A315-21 Battery Won't Charge

Creolex

The battery in my Aspire A315-21 battery won't charge.  The laptop recognizes the battery but It is not charging and show 78% charged. 
- When I unplug it from the AC it shuts off and won't start.
- I tried to do a battery re-set by placing a pin in the pin hold near the memory but that wasn't successful but could be user error
- It is my understanding that there is a switch that the lid for the memory access engages to keep the battery on but looking at the video that part (circled in red in picture) is absent from my laptop. I am not sure if it was there and was accidently removed when I replaced the memory.

I want to make sure the battery is bad before I replace it and have the same issue. Any help is appreciated. Thanks!

Go to the elevated command prompt.  Enter 'powercfg /batteryreport'. Then return to the desktop. Open file explorer. Then search for' battery-report.html' in the c:\windows\system32\ sub-folder. Double-click to open it in the browser. Post screenshot of the first part of the report if possible that compares design full charge capacity with its remaining full charge capacity. Jack E/NJ

Well the battery's lost about 40% of it capacity. Not too shabby for a 3+ year old battery if it's internal charge controller is OK.

Do you have an AcerCareCenter or another 80% charge limit app turned on?  If yes, you can try to re-calibrate it using directions in this link.

However, in my opinion, it's best to disable any charge limiters, go into Device Manager to uninstall all the drivers in the batteries folder, then reboot and try recalibrating by running the battery through a few 100% full charge to 90+% discharge cycles to see what happens.

I do not have AcerCareCenter installed. To the best of my knowledge I do not know if I have any 80% charge limit app that are turned on....I uninstalled both drivers, removed and re-installed the batteries and reboot with the same results.  I have not tried recalibrating.  I am not familiar with charge / discharge cycles.... I am learning this stuff on the fly. Thanks

How do I download the Acer Care Center if it is necessary?  When I go to Acer support the only app in the application folder is the Quick Access Application.

(1) To re-calibrate, turn the laptop off with the charger plugged in.

(2) When the blue charge LED turns from solid orange to solid blue. Turn the laptop back on.

(3) If the charge LED remains blue after Windows boots, then remove the charger.

(4) If the laptop immediately shuts off, then replace the battery.

(5) If the laptop stays on, continue to use the laptop unplugged until the Windows low battery warning which means battery is 90+% discharged.

(6) Plug the charger back in. The battery should be recalibrated when the charge LED turns from steady orange to steady blue again.
