Possible to run computer on AC, without charging battery?

The Thinkpad window is exactly what I would like to have on my Acer! A way to self decide how to charge/ cycle the battery. I guess only thing to do is smile and use up the battery, then eventually look if there still will be a replacement battery available somewhere...

Thinkpad is one exception.

I'm embarrassed to say that I own a Thinkpad. (A low-end one.) I've never noticed that feature. (Rarely use it off the charger.)

Full-featured Thinkpad Power Manager was preinstalled in Windows 7, some crippled Lenovo app (which cannot set the lower limit where to start charging) perhaps can be installed from Store. Windows 10 actively refuses to install good old Power Manager ("This app can’t run on your PC¨) so it is very difficult and tricky to make it working. And each feature update uninstalls it so repeated installation of it is needed.

I have Lenovo, Dell, and HP laptops-for home and travel, and all of them have helpers, assistants, whatever you want to call the programs. If your Asus has something like that, you might find a battery management feature in that program-where you can set the computer to stop charging (such as 95%) and begin charging at a level you specify.

So Lenovo Vantage already can set both limits. Not as of 3 years ago when I need it.

Hello!
Does anyone know if it is possible to somehow let the computer (Acer Swift 3) stay connected to AC, but without constantly having to charge the battery fully up to 100% ? Does windows 10 have some options in this matter?

Thanx!

I have a Dell ( 8 yrs. old) and an Acer (3 yrs old) both batteries were dead.
I bought new batteries for them and none of them last long.
Finally I ditched the batteries and just plugged them into AC outlet. Been doing that for 2 yrs without any issue.

Just a thought-have you checked to see what the charging threshold is? I mean disconnect the AC and run the battery down to 97% or 95% or 90% and then re-connect the AC and see if it charges back up to 100%.

Computer and battery is new, so all is working perfect. Im just concerned about the fact that I cant choose to let the PC run only on AC, i have to use up the lifespan of the battery, even when at home.

If I let the PC stay plugged in to AC, the battery obviously will get fully charged and then remain at 100% (or 4,2 volt / cell), this will wear out the battery more than if the battery could be left at a fixed level of fx 80%, even when connected to AC.

If i understand it right, the charging circuits inside the battery don't let the battery "exercise" from fully charged down to lower volts as long as the computer is plugged in to AC, but is rather monitoring and balancing the actual charge process so that each cell is charged up to the same volt level.

Well anyway, hopefully it will be possible to eventually install a new battery, when or if that ever will be necessary...
