I've seen issues with Modern Standby on my fleet of Lenovo ThinkPad Yoga L13 and L13 Gen 2. Usually everything is fine, but sometimes they get super hot in standby as well. It's like something is keeping the CPU awake but the rest of the hardware is asleep (including the fans). My older units (ThinkPad Yoga 260, ThinkPad Yoga 370, ThinkPad L380 Yoga, ThinkPad L390 Yoga) never had any problem like this because they don't support Modern Standby.

It's very annoying that MS doesn't allow us any way to disable Modern Standby. OEMs still haven't figured out how to make old school sleep perfectly reliable. Springing a new standby model on them was doomed to be just troublesome.

Modern Standby is an Intel thing, not a Microsoft thing. Intel has just pressured Microsoft and other OEMs into supporting it. IMO, it's a huge steaming pile-o-crap, and one of the biggest reasons I want my next PC to have a non-Intel CPU. Intel has shown over the past decade that they are quite simply incapable of implementing properly functioning power management, and I'm tired of having machines die because of their stupidity.

I've had two Surface Pro 4's (one of the first "Modern Sleep" devices) develop battery bloat because of this Intel's power mgt incompetence. Microsoft replaced both, but what is this crap costing all of us, both in higher hardware prices and environmental waste?

FWIW, I haven't needed a faster CPU in years - I need more RAM, long, long battery life, and sleep/wake that always works, instantly. If the iPad were capable of being a real computer, it might get me back into the Apple fold, if iOS had a usable UI...

FWIW, it is not an Intel thing. I got an Asus G14 2021 which has nothing Intel (Amd CPU and nvidia GPU) and this does not support S3, only the modern "connected standby" crap.

Talk about ruining a perfectly working solution for almost no gain.

My lenovo laptop has an option to force S3 standby in the bios, you just choose "Linux" instead of the default "Windows 10" sleep mode.

Not sure if this is related, but I have a 2021 Legion 5 Pro, and even fully powered down it seems to lose a lot of battery power overnight. (Maybe 5%-10% charge, IIRC?)

And this is even after changing the BIOS setting so that it's always-on USB port isn't always on.

I'm really curious where the power is going. Or if the supplied battery has internal leakage issues.
