They never fail, true, but there is always some special model capabilities that can only be made available after the usual weekend and late nights fine tuning.

I never had to tune anything on my old EliteBook 850G2 (That thing was new when I got it), and had ~8 hours of battery life from get go.

Some higher end devices of course need it (esp. in the biometrics department), but rest is automagic now, as far as I experienced.
