Can Windows 11 sleep?

This confusion has been brought about from people who have bought new laptops who have motherboards that only support modern sleep.As a result, these laptops do not 'behave' as they are accustomed to. Modern standby has serious issues which include overheating, battery drain, and loss of certain functionality when the laptop enters S0 sleep. It's not an OS issue, but the lack of S3 support of the hardware. People buy these laptops unknowingly of what they are getting and what problems they will have to deal with. Modern Standby was originally Microsoft's idea, but OEMs and mobo makers have made it so that the user doesn't have an option of using any other sleep state, which, depending on how one uses their laptop can cause havoc on the batteries and constant overheating of their hardware if the laptop is carried in a case. From a consumer standpoint, IMO it's a nightmare. I don't expect anything to be done about it, though.

Good info, glasskuter. Personally, even prior to modern standby, I never liked putting a laptop into standard sleep mode unless I was leaving it on a desktop. I've had cases where I pulled a laptop out of a backpack to find out that it woke up while in this enclosed space with no ventilation, so the laptop was excessively warm. So, if I'm packing away the laptop, I will either perform a standard shutdown or a hibernate.

I like all my laptops to go into sleep when I close the lid, and to wake on opening the lid. I like how I can instantly carry on from where I left off. But I'm just as likely to close the lid and move on to another machine, maybe not returning to the first one for days. So all my laptops are set to hibernate after 20 minutes of sleep.

With my first Modern Standby machine it took a while to work out how to make it do the same thing.

I have never owned or used a machine with modern standby so an experience that is completely foreign to me, but it definitely sounds useful, especially if you are going to use a system as a tablet.

My new laptop has Modern standby. One night I just closed the lid and left it plugged in. The next day it was so hot that it wouldn't turn on until it cooled off. I don't know if I left some programs running or it was caused by the brief power outage we had over night. I haven't check to see if my wife's laptop has Modern Standby.

Wow, that's crazy. You would think that cooling would kick in, or if no active cooling, thermal throttling, or SOMETHING to prevent that kind of scenario.

Amongst the activities that S0 suppresses is anything the user has set up in Task scheduler.
- Reports of overheating make me think that cooling is also suppressed but that beggars belief.

There are, in effect, four Power/Computer states for an S0 Modern standby [aka S0 Low power idle] computer
- Computer on, Monitor on {Work can be done on the computer}
- Computer on, Monitor off = S0 {The monitor turning off initiates S0 Modern standby i.e. idle}. No user-desired activities take place, only MS-desired ones such as WU & their built-in email app.
- Hibernate
- Off

Note that proper sleep [i.e. S3 Sleep] is not available on an S0 computer.

S0, the progressively severe idle condition, is not so energy-efficient that you can leave your computer sitting there in the corner on battery power until next Tuesday [unlike your phone]. It won't even sit there until tonight then still have enough power left to allow you to use it for a few hours. I think S0 is a decade too early; when computer hardware can idle on as little power as a phone's hardware then S0 will have a point.

I do hope you are impressed by the fact that I have referred to S0 several times in this post without adding appropriate adjectives to it. It has taken a lot of self-discipline to achieve this. S0 is a curse.

Yours,
an S0 victim,
