Why is the battery indicator stuck at 87%?

Hey guys,

I have just done a factory reset and turned on that 80% limit in acer sense. The system said it would charge to 100% for calibration purposes and then life would go on as normal. Now the battery charging is stuck at 87%. Any ideas why?

It wasnt the 3rd calibration option. It was just turning on the 80% charge limit.
Btw, does restarting the laptop interrupt this process?

Thanks.

    I recommend uninstalling AcerSense and not use any battery monitors/calibration/charge limiters bloatware as these apps are not based on any scientific research and just parroted myths from the internet. Li-Ion batteries have a Smart chip that regulates the charging with BIOS and interrupting the battery charging adversely affects Microsoft ACPI battery protocol, BIOS and Modern Stanby mode. After you have uninstalled Acer Care Center and AcerSense check Windows Services for any AcerAgent or accSVC services still running, stop these and disable the Startup type in properties and click on Apply. Also check in Task Scheduler-Library if any Acer Agent tasks are Ready or running, disable these too.

    Go to Device manager, expand Batteries, right click Microsoft ACPI-Compliant Control method battery and select Properties, move to Driver tab and uninstall it, then reboot and let Windows install the driver and see whether it  helps.

    Thank you for commenting.

    Let me see if I understand it correctly: Does this mean that I can charge my Acer laptop's Lithium battery to 100% and the laptop will just turn off the battery charging and use the power from the charger directly to power the laptop?

    Yes, most modern machines have smart enough charging circuit to stop charging when full and restart when the level drops, no need to artificially limit it.

    Like Billsey says, don't worry about overcharging the battery, leave the power adapter plugged in 24/7 and make sure the battery is always fully charged: https://www.computerhope.com/issues/ch001587.htm
