Hold my pint
Well, wife's pint really.
She has a fairly recent HP Envy laptop (yep, win11, but otherwise pretty high spec) that's *never* shutdown properly. Power off, leave for a few days, power on with ... you guessed it ... reduced or no battery. Even the commandline "fix" given here doesn't work.
"Have you tried the HP community boards?" you ask? Well, yes. Lots of responses along the lines of "find the windows menu, click the "power off icon" which looks like this blah blah blah. Ffs. HP's support the same.
Which all leads me to the inevitable conclusion that MS are merely trying to catch up with HP in enshittification.
