@nicole.faerber, are you saying that the librem 14 can take 20 V, 21 V, 22 V, … DC? so the voltage specification is merely an approximate lower bound? that’s very interesting because i had (apparently wrongly) gotten the impression that computers in general were quite picky about getting an exact voltage, plus or minus perhaps 1 V. of course, i don’t even know what a volt is.
