> Sleep & suspend doesn’t work on Windows either.

What's strange is that it never used to be a problem. There are five Windows laptops floating around our house at various times (mixture of work and personal) and suspend works properly on none of them. Oddly, it works on my personal laptop with Debian Stable almost every time, failing maybe 1/25 times. Other distros are about the same as Windows.

Modern Standby. Windows wanted to do the Apple "power nap" stuff, but never realized how painful it'd be if you don't control all the hardware and have millions of different hardware permutations (with a lot of terrible drivers) instead of just a few. Not that it would've helped, half the time my machine is either overheating or off it seems to be wake timers doing windows updates (which yes, you can disable, but most wouldn't).

I don't get why S3 sleep had to die for this, but it did.

I'm super happy with S0 on Linux. The implementation is all about doing as little as possible but effectively remain "on".

What's the point, though? If it doesn't actually do anything, why keep it on?

[lillecarl]

Because you don't have to reinitialize hardware if you don't shut it off. Which is hard and causes problems. It's easier to just go into power saving++.

If you want your device to be off, power it off.

On Linux, you can run a systemd unit file that will trigger `rfkill` on sleep and a different `rfkill` invocation on wake and you effectively dodge all that crap because the laptop isn't connected to WiFi and thus will sit around realizing its spinning its wheels and wil shut down further down the s0 chain.

> I don't get why S3 sleep had to die for this, but it did.

Worse yet, the dirty little secret is that many laptops that offer both S0 and S3 will actually drain more energy in S3 than in S0 because the S3 mode has had poor QA.

My colleague showed me his windows machine recently. The rubber on the back around the fans has melted from the times he forgot to shut it down and sleep didn't trigger when he packed it away in his backpack.

Linus tech tips on YouTube did a video about a windows bug where sleeping while charging would allow the laptop to wake up to check for updates etc but often caused this issue of turning on in a bag

[whizzter]

It wouldn't happen that this feature was released around early/mid 2020? Windows sleep used to be semi-reliable but one it's been shit for a couple of years.

(Any link to the video/docs for turning it off?)

Search "LTT Windows Modern Standby" on YouTube. Sadly all the workarounds to turn it off no longer work reliably. For reliable sleep, buy a Framework (only current Windows laptop that still supports S3 Sleep) or Macbook.

TL;DR pull the the plug from the laptop _before_ closing the lid. That way it will not be sleeping thinking it got power from the wall.
