I was happy with this setup since it is better than to have no threshold control at all. It will only revert to original state (charges up to 100%) if I power off my laptop, unplug the adapter, power it on and boot to Ubuntu directly without going first to Windows or if I set it to 100% using the battery app in Windows. Even thought I disconnect the power adapter and allowed it to drain the battery, plugging it in again charges it up to 59% or 79% depending on the preset threshold (it is always 1 percent short than the indicated threshold level).

60% before rebooting to Ubuntu 18.04 (without powering off or shutting down) will persist the charge threshold. (next time I'll be buying Thinkpads instead).īut I found out that booting to Windows and setting the charge threshold to i.e. I've learned that the driver to make this work is vendor specific and that Asus has no driver support for Linux like Thinkpads does with TLP. I use the battery only if I work while on long trips, so I searched for a similar app for Linux. I plug my laptop whenever there is an AC power available and it stays plugged in when I'm working. But since I only use Windows 10 for gaming, I've setup my working environment and install Ubuntu 18.04 dual booting on Windows 10. I owned an Asus X405UQ which came with this Battery Health Charging app that controls the charging threshold.
