My X1 Carbon gen 6 got hit with the dreaded Sleep mode Power Suck issue. Drawing anything from 500mW to 3W during sleep. Diagnoses shows NoDrips and various FX controllers and all sorts of esoteric stuff refusing to hibernate, different everyday.
The computer gets regular updates directly from Microsoft and the manufacturer. No funny software on it, at all. Rifled through BIOS settings, disabled all telemetry and other devious background processes, still same problem.
This issue plagues pretty much every Windows machine I've had. Even the corporate laptop which is ultra-locked down, battery will fully drain over 2 or 3 nights of sleep. When plugged in sometimes the fans will go full tilt for days on end, with seemingly nothing being run and regardless of whether its awake or asleep.


All of which is to say ill be jumping back into the warmth embrace of an Apple laptop this holiday. Just too bad the ARM machines wont have been released by then.
