Does anyone know if these processors support System Power State S3 (Deep Sleep)?

I thinking of getting a new PC. I prefer the older S3 Sleep over Modern Standby. Anyone know if these processors support S3?

12th Generation Intel® Core™ i5-12600T
11th Generation Intel® Core™ i5-11400T
11th Generation Intel® Core™ i7-11700T
10th Generation Intel® Core™ i5-10400T
10th Generation Intel® Core™ i7-10700T

Rick,

I suggest you ask Intel so you can rely on the answers given.
www.intel.com/content/www/us/en/support/contact-intel.html#support-intel-products_873:873
www.intel.co.uk/content/www/uk/en/support/contact-intel.html#support-intel-products_873:873

I had a look at their specs page for 12th Generation Intel® Core™ i5-12600T and doing so brought up a request for feedback that I used to moan about the info not being included in their specs.
I wrote:-
Problem: I wanted to know if a CPU supported S3 Sleep or not [rather than just S0 Modern standby aka S0 Low power idle]
Suggestion: Include support for S3 Sleep in CPU specs

I also want to avoid the cursed S0 Lower power idle for my next computer [in a few years] so I'll be very interested in how Intel deal with your query.

Best of luck,
Denis

Ha... yea, I looked at their site first but couldn't find the answer. I just initiated a chat. I'll post back the results.

I have the 10th Generation Intel Core i7-10700, but it's in my desktop. It's compatible with Windows 11.

There is a discussion of S3 sleep here: Does S3 sleep work in Windows 11? which may help you.

I know nothing about S3, so will learn with you.

Can you open a command prompt and type powercfg /a? It will tell you what states are supported.

Sure:

The following sleep states are available on this system:
Standby (S3)
Hibernate
Hybrid Sleep
Fast Startup

The following sleep states are not available on this system
Standby (S1) The system firmware does not support this standby state.
Standby (S2) The system firmware does not support this standby state.
Standby (S0 Low Power Idle) The system firmware does not support this standby state.

Thanks. I followed the guide here to enable it my system...


by adding the regkey. After that, powercfg /a now showed S3 as available and my system now enters true Sleep. Hopefully, the above processors will support it but who knows.

Wynona,

[I type slowly. I only saw Rick's reply to you after completing this post.]

So your computer does have S3 Sleep, which is what people generally mean when they refer to sleep. I'm pleased for you.

S3 Sleep is, in MS's opinion, the old standard that MS thinks "users" regard as not good enough because "users" want "instant-on" like we have on our phones. It's a bogus claim.
- A computer resuming from S3 Sleep does so in little more than the blink of an eye.
- A computer in S3 Sleep can last for a day or more before its battery gives out.

I have an S0 Modern standby computer [actually a tablet but with its own integrated keyboard so it looks like a small laptop].
I disabled S0 but, unlike the experiences of any others who have done so, my S3 Sleep remained disabled.
So I have the choices of being fully on, being in hibernation or being off. This is still better than having S0 messing things up.
Disable Modern Standby in Windows 10 and Windows 11 - ElevenForumTutorials
I also tried a halfway stage that stopped S0 starting: Power options set to keep the monitor on always plus a blank screensaver that started after a minute or so. The 'on' monitor was therefore not staring at me the whole day. I wasn't a bad compromise.

There are many forum discussions about the curse of S0 Modern standby.
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

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.

Like Rick, I am determined to avoid buying another S0 computer.

Yours,
Another S0 victim,
Denis

So I was in the chat for a long time with the Intel agent. Finally, she asked if she could research it and get back to me. She couldn't find the info. She said it could take 48 hours. You would think that this would be easy for them to look up.

Rick,

Fingers crossed for Friday then.

By the way, if you do get any strange hardware misbehaviour after resuming from S3 Sleep then reinstalling the relevant driver might well fix things.
- I found that my WiFi adapter didn't work correctly when resuming from hibernation [my nearest equivalent now] after disabling S0 and several others reported the same thing about resuming from their now-re-enabled S3 Sleep
- In my case & the other reported cases I saw, re-installing the relevant driver fixed things permanently.

Denis

That's good to know, thanks Denis. One thing I noticed with my current system which I added the regkey to... I need to push the Sleep button on my keyboard for only about 1/2 second for it to sleep. If I hold it down longer, the system force reboots... and NOT gracefully. It's like holding the power button for 10 seconds to get a system to turn off.

I have never seen this but, if the power button itself makes you wait 10 seconds, perhaps it is some "helpful" feature of your keyboard.

I think I have a sleep button on one keyboard [my Windows 11 test computer, a laptop]. I'll dig it out and see how it behaves. False memory.

All the best,
Denis

With my modern standby WHICH IS GREAT, I press button for fraction of second (not even 1/10th) and pc sleeps, press it for same short period and it wakens.

When I do regedit, S3 behaviour is unreliable and it is Russian Roulette whether it works properly (I did try updating drivers).

IMO, you are fighting a losing battle avoiding Modern Standby. The main gripe was overheating when left in a bag when travelling but only an idiot (imo) would use sleep when travelling. Either turn off laptop or use hibernate.

I have not experienced a single issue with modern standby, and laptop responds instantly. So frankly, most of the hype about its bad points is exaggerated bs (probably based on very early implementations).

Martin,

I'm sorry but I disagree with you.
- You do not have Sleep in the sense that the term is normally used i.e.S3 Sleep. S0 modern standby [aka S0 Low power idle] is an idle condition not a replacement for S3 Sleep.
- S0 progressively inhibits your own tasks running once Power options turns the monitor off. If that isn't a problem for you then fine, S0 seems suitable for such cases as yours.
- My own S0 worked as it was supposed to. It had no issues. The problem was the mismatch between its behaviour and my requirements. I had never even heard of S0 before 2018 when I bought that computer. That emphasises Rick's wisdom in getting answers beforehand.
- People's experiences after disabling S0 have varied. In my own case, I was disappointed that S3 Sleep did not get enabled but many others found that it did & many posted reports of having to reinstall a hardware driver. Until your post I had not seen a report of the now-enabled S3 Sleep being unreliable. That further emphasises Rick's wisdom in getting answers beforehand.


All the best,
Denis

When I said 10 seconds, I meant like when Windows is locked up and you need to hold the power button down for 10 seconds to turn it off. Once it reaches that 10 seconds, it just turns off hard. That's what happens to my Lenovo if I hold the sleep button down for more than 1/2 second or so.

My issue was the fan. An hour or so in Modern Standby, the system fan would go into overdrive for one reason or another. I don't know what the system was doing ( I wasn't able to pinpoint it) but it would continue like that for maybe 20 or 30 minutes. No thanks, I'll stick with S3.

- - You cannot S0 your computer until tomorrow morning then expect to use it on battery for several hours. My S3 Sleep laptops only consume about 0.5%-1% of battery power for every hour they are in S3 Sleep.​

- - The problem of overheating in luggage was, in my opinion, a failure of communication. People thought their new computers behaved like S3 Sleep did. They did not appreciate S0's high power consumption compared to S3 Sleep.​

- - My only S0 computer could not start tasks using Task scheduler once S0 kicked in. I do not know how widespread that limitation is but it's consistent with MS's descriptions of S0 behaviour.​

- S0 progressively inhibits your own tasks running once Power options turns the monitor off. If that isn't a problem for you then fine, S0 seems suitable for such cases as yours.

You can disagree as much as you like. My comments are based on experience of two laptops and I have no issues whatsoever.

I do not give much creedance to argument about using S0 and then wanting to use battery for several hours next day.

Just use hibernate instead. I normally turn laptop off anyway. I use sleep a lot during day and love its instant response.

My point is most laptops will come with modern standby and if one thinks enabling S3 is the solution, prepare to be disappointed.

In the end, everybody's mileage will differ.

If enabling S3 works for an individual fine, but everybody seems to think S0 is bad - it certainly is not, you just need to understand it and adjust behaviour accordingly.

In my opinion, its positives outweight the negatives.

It has been my understanding that it was Microsoft who came up with this great (not) idea of modern standby and convinced the manufacturers to go along with it. The manufacturer's have to use certain hardwares that comply with it as well as issue bios that control use of it. Device-specific power management for modern standby

It's my opinion, and someone correct me if I'm wrong here, but I do not think it's the CPU that dictates whether a laptop uses modern standby or not.

The issue of modern standby has been beaten to death in this and other forums across the web. What is most troublesome to me about it is that unsuspecting users who have been accustomed to S3 sleep buy these systems expecting them to work the same way. It's only a very small percentage of people who would know to use hibernate instead of S0. In fact, they do not even know what hibernate is. It's not that they are idiots. It's just that they have little understanding of the workings of a computer. Very few people are geeks like us.

fair point about geeks as I said same on another post LOL.

I must admit it is an age thing but early laptop users understood hibernate, sllep was not effective enough and we knew we had to use hibernate to save bettery if travelling Indeed we had to park the hatd drive before travelling. LOL.
