Default What's it doing behind my back?

Windows 10 Pro 1709 (16299.248)

Even when I am doing nothing on my system, my internet activity light on my
router port keeps blinking merrily away. As a test, I put my system to
sleep last night. After the screens went dark and the keyboard LEDs turned
off, my disk activity light and the aforementioned activity light kept on
for over two minutes. All my disks are set for immediate writes, so there
should be little if any disk buffering to finish writing. So what is
Windows doing for those two minutes that results in continuous disk
activity? And yes, the internet activity light finally went out at the same
time the disk activity one finally went dark.

S3 Sleep
S3 Hybrid Sleep (writes to hiberfil.sys first, then sleeps) --- power safe
S4 Hibernate (writes to hiberfil.sys) --- power safe

From an Administrator Command Prompt

powercfg /h off

disables both Fast Start and removes the hibernation file,
so that Hybrid Sleep and Hibernate are no longer options,
and when you select Sleep, the delay for Sleep to start
is a lot less. It's still not a zero delay, but there's
less trailing-end-writes when you try to sleep Win10.

I disable hibernate, just to reduce the size of the space
taken by hiberfil.sys on SSD drives.

My wife's Win 10 machine does have the sleep option--only hibernate.
Is there a way to get sleep back, or is there no sleep mode in Win 10?


At one time, there were two tick boxes for this.

https://winaero.com/blog/add-hiberna...in-windows-10/

And I just tested here, and they're still accessible.

1) To get to Control Panels, you can use Right-Click-Start : Run or you
can use Cortana and try "control" there as a word to type in.

2) Then, it's Power Options in the Control Panels.

3) There is a Power Button item at the top of the left menu. Use it.

4) Below the text in the resulting window, is an option to
make the "missing" buttons visible and ready-to-edit.

5) After that, tick the boxes as desired.

I didn't know you could make it go away.

Open a command window with administrator authority

powercfg /a will tell you what sleep states are available on your system.
For instance, my system has Standby (S3), Hibernate, Hybrid Sleep, and Fast
Startup Available.

I have turned Hybernate off using the /H option.

I don't see any option for making Sleep go away

There are several commands you can try. First,
we need a Command Prompt.

If you right-click the Start Orb, there will be either
an Administrator Powershell or an Administrator Command Prompt.

If the Powershell happens to be the one in your menu,
you can type "cmd.exe" into the Powershell window, to switch
to Command Prompt syntax. I find the startup of Powershell
to be a little slow, so I prefer Command Prompt in my menu,
and type "powershell" into Command Prompt if I need Powershell.

There is also a Settings menu which can change the right-click
menu to offering Command Prompt. Using the search box in Settings
may cough up the correct pane to correct the choice in your
right-click Start menu.

https://www.tenforums.com/tutorials/...dows-10-a.html

*******

In any case, from an Administrator Command Prompt, this
may tell you what is blocking sleep. Wait patiently, because
it's actually doing a C-state analysis in real time, and the
more static S-state information that would be ready almost
immediately, you have to wait until it finished some sort
of C-state stuff first. (C-states save processor electricity usage
when the desktop is idle.) After 60 seconds, it should belch
up the report, in your choice of locations. You are looking
for messages that talk about your "S3 Sleep" problem.

powercfg -energy -output %USERPROFILE%\Desktop\Energy_Report.html

For example, in my Win7 in a VM setup, this is my "blocker":

"System firmware (BIOS) does not support S3"

A Windows 10 compatible system, isn't likely to report this,
because the CPU compatibility requirements force operation with
more modern motherboards, where that BIOS setting isn't there
any more. (I.e. The BIOS leaves S3 enabled in the ACPI or
Power settings section.) If you managed to run Windows 10
on the last model of Pentium 4 they made, you may have
a BIOS with "S1 only" or "S1 & S3" choice in the BIOS Setup
power section. And "S1 & S3" support is the one you want for sleep
applications.

This next report is mostly useless, because it reports the
co-operating hardware items, not the blocker.

powercfg -devicequery s3_supported

That one lists lots of things that support S3 sleep, but it
won't tell you about critical (i.e. real hardware) ones
that are blocking sleep.

And this one, if the system sleeps for ten seconds and
then wakes up, this will tell you what hardware device
asserted PME and woke the system. If it wakes in 10 seconds,
when your hands weren't touching the keyboard or mouse,
that's the NIC "wake on carrier" setting. In Device Manager,
you can do Properties on the NIC, and disable all forms
of waking from there. Then the system will stay asleep.

powercfg -lastwake

So plus or minus syntax mistakes (using "/" versus "-"
in the command format), those are some ideas for tracking
down the problem.

In previous times, we would use "dumppo" for this kind of
debugging, but I think in at least Windows 10, dumppo no
longer works. And then it's

powercfg /?

to the rescue, in an Administrative Command Prompt.

Also, I think recovery from BIOS mis-configuration is
automated in Windows 10. We needed "dumppo.exe" in the
past, because older OSes would "drive off into a ditch"
and not recover from the BIOS mis-setting of "S1 only".
Dumppo could be used to override the "poor sleeping habits"
of WinXP for example. But in Windows 10, if you did have
a BIOS settings problem, once the BIOS is corrected and
you boot, your sleep problem should then be solved.
The powercfg energy report would then no longer show:

"System firmware (BIOS) does not support S3"

as my little sample setup did.

HTH,
Paul

For instance, my system has Standby (S3), Hibernate, Hybrid Sleep, and Fast

Here is what I have found so far. I turned off Classic Start and with
it off, the shut down menu had Sign Out, Sleep, Shut Down and Restart
options. With Classic Shell in use, the options are, Switch User, Log
Off, Lock, Restart and Hibernate.

I use Classic Start on my Win 8 Dell Laptop also, and the menu on it
has, Switch User, Log Off, Lock, Restart, Sleep and Hibernate. Don't
know if this is a Win 8 vs Win 10 thing or not, but will check the
respective .ini files for differences.

I used powercfg /a and found:
C:\WINDOWS\system32powercfg /a
The following sleep states are available on this system:
Standby (S0 Low Power Idle) Network Connected
Hibernate
Fast Startup
The following sleep states are not available on this system:
Standby (S1)
The system firmware does not support this standby state.
This standby state is disabled when S0 low power idle is
supported.
Standby (S2)
The system firmware does not support this standby state.
This standby state is disabled when S0 low power idle is
supported.
Standby (S3)
The system firmware does not support this standby state.
This standby state is disabled when S0 low power idle is
supported.
Hybrid Sleep
Standby (S3) is not available.

I hope this clarifies things, but I'm afraid it doesn't mean much to
me. Although, since the problem appears to be with Classic Start, I'll
dig deeper into that and see what I can find. Thanks for the help so
far. Let me know if any of you have more suggestions.


Can you get to the BIOS Setup screen ?

The things that are turned off, don't appear "normal". Sometimes
S3 gets turned off, by itself. But all three items shouldn't
be listed that way - it almost implies ACPI is broken, and we
know that isn't true, because you've still got a working
Hibernate (Hibernate is ACPI S4).

Maybe something at the OS level could break those, but that pattern
doesn't really look like a BIOS issue.

BIOS controls include one labeled as "Power Options" or similar.
You might see the word ACPI there. And choices of "S1" or "S1 & S3"
for supported system firmware states. The end result would be,
that S1 would always run. And yet your report shows S1 suspend is
disabled somehow.

The BIOS also includes things like EIST (Intel SpeedStep), as
well as some C-state controls. I don't think the C-state
stuff affects Sleep. Sleep is ACPI S3 state.

It's a long time since I used classic shell, but can't you do something
like press ctrl (or alt, or shift maybe?) while clicking start to get
the real start menu, and just use that when you want to sleep?

I tried a couple options (Del, F-2, F-10) with no luck. Will try
Duckduckgo to see if I can find a way in. Thanks


Here is what I found.
https://surfacetip.com/configuring-s...bios-settings/
None of the settings here that I can find say anything about changing
ACPI states. Closest I could find was "Secure Boot", but there really
wasn't anything there. I'm stumped!


That's OK.

This article says look for another graphics driver,
as if the graphics driver is the "blocker".

http://www.classicshell.net/forum/vi...php?f=7&t=7547

Windows has an "in-box" graphics driver that came from the
manufacturer, but some of those have had egregious bugs.
For example, I have a system here, where the OS driver only
makes "half" of the graphics card work. Downloading a driver
from the hardware manufacturer, makes the *whole* card work :-)

Of course, you have to figure out who made the graphics,
and which driver to use as a consequence. Particularly nasty
are Optimus graphics, an Intel GPU for low power states,
an NVidia GPU for gaming, and the driver switches between
them as required. I hope it's not one of those (I don't
own one, so have no hand-on experience with it).

You can start by checking the Support web page for your
product, and seeing what graphics drivers are offered. In
some cases, on sufficiently custom equipment, those are
the only drivers you can get. Sometimes the formulation
of the driver, tells you who made it, and maybe you can then
figure out an alternate sources.

If you know of a web forum where disgruntled owners meet,
you might get some info on graphics drivers there. As in
"what is the best driver".

I've successfully used information in the past like that,
a couple of times. Some people chatted up a certain WHQL
certified driver for my hardware, and they were right. The
driver worked, didn't crash, and generally left me happy.

On average, when you do your own computer maintenance, you
will test around three video drivers, until happy.

One ATI card I bought, the driver in the box, on the CD,
caused an immediate crash. When that happens, you know you're
going to use up your "average of three test drivers"
pretty fast :-)

A Windows 10 compatible system, isn't likely to report this,
because the CPU compatibility requirements force operation with
more modern motherboards, where that BIOS setting isn't there
any more. (I.e. The BIOS leaves S3 enabled in the ACPI or
Power settings section.) If you managed to run Windows 10
on the last model of Pentium 4 they made, you may have
a BIOS with "S1 only" or "S1 & S3" choice in the BIOS Setup
power section. And "S1 & S3" support is the one you want for sleep
applications.

This next report is mostly useless, because it reports the
co-operating hardware items, not the blocker.

powercfg -devicequery s3_supported

That one lists lots of things that support S3 sleep, but it
won't tell you about critical (i.e. real hardware) ones
that are blocking sleep.

And this one, if the system sleeps for ten seconds and
then wakes up, this will tell you what hardware device
asserted PME and woke the system. If it wakes in 10 seconds,
when your hands weren't touching the keyboard or mouse,
that's the NIC "wake on carrier" setting. In Device Manager,
you can do Properties on the NIC, and disable all forms
of waking from there. Then the system will stay asleep.

powercfg -lastwake

So plus or minus syntax mistakes (using "/" versus "-"
in the command format), those are some ideas for tracking
down the problem.

In previous times, we would use "dumppo" for this kind of
debugging, but I think in at least Windows 10, dumppo no
longer works. And then it's

powercfg /?

to the rescue, in an Administrative Command Prompt.

Also, I think recovery from BIOS mis-configuration is
automated in Windows 10. We needed "dumppo.exe" in the
past, because older OSes would "drive off into a ditch"
and not recover from the BIOS mis-setting of "S1 only".
Dumppo could be used to override the "poor sleeping habits"
of WinXP for example. But in Windows 10, if you did have
a BIOS settings problem, once the BIOS is corrected and
you boot, your sleep problem should then be solved.
The powercfg energy report would then no longer show:

"System firmware (BIOS) does not support S3"

as my little sample setup did.

HTH,
Paul


Nothing in your log looks promising.

Nothing sticks out like a sore thumb as it were.

By any chance, is your machine one of these ?
It seems MSFT drank too much Intel Koolaid.

S4 Hibernate (writes to hiberfil.sys) --- power safe

From an Administrator Command Prompt

powercfg /h off

disables both Fast Start and removes the hibernation file,
so that Hybrid Sleep and Hibernate are no longer options,
and when you select Sleep, the delay for Sleep to start
is a lot less. It's still not a zero delay, but there's
less trailing-end-writes when you try to sleep Win10.

I disable hibernate, just to reduce the size of the space

My wife's Win 10 machine does have the sleep option--only hibernate.
Is there a way to get sleep back, or is there no sleep mode in Win 10?


I don't know about your wife, but on my win7 laptop, Hibernate
disappeared one day, even shutting the lid is still set to hibernate and
it does. But it's not in the list that shows when you click on Start.

So maybe you can get shutting the lid or pushing the power button to
sleep it. Of course you need the power button for turning it off when
it won't turn off.

There are several commands you can try. First,
we need a Command Prompt.

If you right-click the Start Orb, there will be either
an Administrator Powershell or an Administrator Command Prompt.

If the Powershell happens to be the one in your menu,
you can type "cmd.exe" into the Powershell window, to switch
to Command Prompt syntax. I find the startup of Powershell
to be a little slow, so I prefer Command Prompt in my menu,
and type "powershell" into Command Prompt if I need Powershell.

There is also a Settings menu which can change the right-click
menu to offering Command Prompt. Using the search box in Settings
may cough up the correct pane to correct the choice in your
right-click Start menu.

*******

In any case, from an Administrator Command Prompt, this
may tell you what is blocking sleep. Wait patiently, because
it's actually doing a C-state analysis in real time, and the
more static S-state information that would be ready almost
immediately, you have to wait until it finished some sort
of C-state stuff first. (C-states save processor electricity usage
when the desktop is idle.) After 60 seconds, it should belch
up the report, in your choice of locations. You are looking
for messages that talk about your "S3 Sleep" problem.

I ran CPU-Z and it shows a Kaby Lake-U/Y CPU Intel Core i5 7300U, Not
a Skylake as in the article. However, powercfg /a reported the same
thing as the article. (See my post of the 20th at 11:44. I tried
disabling Classic Start and hitting Sleep from the Win 10 shut down
menu and nothing happened. It's as powercfg reports, none of the "S"
states are available except S0. Since there doesn't appear to any way
to make any useful changes to the BIOS in Win 10, it would appear that
I'm stuck. I really appreciate all your help, thanks! I'll watch for
any further suggestions you may have.

According to Microsoft:

Systems that support Modern Standby do not use S1-S3.

[No reason for Sleep in the menu???]

That's what the S0ix is partly for. The S0 means it's awake
in some sense, but the thing doesn't use much power when in
that state.

And the part I don't get, is what controls the screen backlight
and screen presentation ? Maybe the ACPI subsystem is still running
and keeping state info, and S1-S3 would cause the screen to go black ?
Independent of the S0ix keeping the machine Always Connected.
