So I wanted to do battery life extension by turning on the charge limit thru Acer Care Center. I downloaded it through the Drivers page of my laptop's model. But then when I try to run it, it shows that message 'Acer Care Center is still initializing…' message. Reboot, still the same. Uninstall, reinstall, still the same. Then I searched and some said to use instead the version from MS Store. I tried to install it, but since there is one installed, I was just given the choice to 'Open' it. Same thing, that initializing message. Then I uninstalled the current version, and the version from MS Store was installed.
So it worked. Unfortunately, my model does not support the batter charging limit feature.
Anyway, for those who can't find 'Acer Care Center' in MS Store, it is at this time of writing, 'Care Center S'. This is the link: Care Center S.
