@7hir7een: Yep, which leads me to my next test, self-contained because you've already suffered through enough reboots for me

.
So, this package is a KUAL extension. It'll add a "Test KOA2 stuff" button in the "Helper" menu.
It should print the result of the tests at the bottom of the screen, like on my PW2 (where the second test is blank, because it doesn't exist, yay!).
The idea is to run it while you're unplugged, to see which value I can trust
