Hi, I’m a Linux newbie with a fresh Manjaro install on my Eluktronics max-15. System runs fine on AC, but when I unplug it I quickly encounter a number of issues: the system hangs periodically, inputs are duplicated (I type “a” and “aaaaaaaaaa” appears), my computer randomly goes to sleep, and the wifi may disconnect and be unable to locate any networks. I have no such issues running Windows on the same computer. Any help would be appreciated!
