Hi, I've been having the exact same problem as them, MyAsus worked fine until recently when I have to keep manually reselecting maximum lifespan mode whenever I turn the laptop on or it will charge itself to 100% automatically. I reinstalled MyAsus but it has not fixed anything, I tried to install the latest ATK package but could not find it on the Asus page for a Asus TUF 505GM on Windows 10 64-bit. I found some installs on a few 3rd party website but when I tried to install the latest 1.0.0061 version I get an error "Unable to install because the setup is not applicable to your computer." for every single ATK Package I try to download that is the latest version. I tried going on youtube for a solution to the error but they do not work for me.
MyAsus used to work fine for me, no problem just plugging it in and automatically having the battery limited to 60%, now there's so many problems and I hope you can help
