What is the command to use to put your computer to sleep (not hibernate)?

Question

I want to put my Windows PC (Windows 7) into a sleep state via command line (so I can bind to macro button on keyboard).

The power button on the PC is setup to but the computer to sleep (but it's down on the floor and I'm too lazy to reach down) it exactly how I want it (sleeps using hybrid mode in case I loose power)

The sleep command on the shutdown menu also works.

most info I found says to use;

%windir%\system32\rundll32.exe PowrProf.dll, SetSuspendState 0,1,0

But this puts the computer in hibernate mode. I do have hibernate disabled but using hybrid sleep.

So, What is the command to use to put your computer to sleep (not hibernate)?

Answer 1

I found a solution. I installed a freeware program called AutoHotKey and recorded the steps to invoke Start Menu -> Sleep into a script file. Then I complied the script file into a stand-alone executable SleepWin7.exe.

Now I simply run SleepWin7.exe to put my computer into hybrid sleep.

You may uninstall AutoHotKey if this is all you need it for.

Update: The above solution doesn't work when the user isn't logged in, i.e. Windows 7 Login Screen. (My computer wakes up at 4am every Sunday to perform weekly backup, which is done without user login.) In such case, the Wizmo program still works:

wizmo.exe quiet standby!

Answer 2

Hope you find these useful.

Shutdown %windir%\System32\shutdown.exe -s

Reboot %windir%\System32\shutdown.exe -r

Logoff %windir%\System32\shutdown.exe -l

Standby %windir%\System32\rundll32.exe powrprof.dll,SetSuspendState Standby

Hibernate %windir%\System32\rundll32.exe powrprof.dll,SetSuspendState Hibernate

Answer 3

See the free utility of Wizmo, which can do very many things.
The command you're looking for is probably:

wizmo standby

Answer 4

to disable hibernate mode you need to use

powercfg -h off

now, rundll32 powrprof.dll,SetSuspendState will put your station in stanby mode

[EDIT]

actually I can't setup for an hybrid sleep because I have a laptop (a state that is not available on mobile stations), for hybrid sleep you need to have hibernation enabled and some say that rundll32 powrprof.dll,SetSuspendState trigger the default sleep mode in your control-panel\power-management settings. please try if rundll32 powrprof.dll,SetSuspendState hybrid sleep give some results.

Answer 5

Make a bat file, where 600 is delay in seconds.

ping -n 600 -w 1 127.0.0.1 > nul

powercfg -h off

%windir%\System32\rundll32.exe powrprof.dll,SetSuspendState Standby

Answer 6

If you're competent with compiling a .NET program the following command will do this

System.Windows.Forms.Application.SetSuspendState(PowerState.Suspend, 
                                                 false,   /* force */
                                                 true     /* disableWake */);

Note: You do not need to disable hibernation as is required by the rundll32 powrprof.dll,SetSuspendState command. You can also use PowerState.Hibernate which will hibernate the machine if you want.

You could easily compile an EXE with this command with any version of Visual Studio. Just create a console application and add a reference to the System.Windows.Forms DLL.

You can create a file with extension .ps1 (powershell) like "sleep.ps1" and write this:

Add-Type -Assembly System.Windows.Forms
[System.Windows.Forms.Application]::SetSuspendState("Suspend", $false, $true)

I use this when I have something running and have to leave the pc and don't want to turn it off. So I change the script to look like this:

$secs = read-host "Enter minutes to wait until sleep";
$minutes= 60*$secs;
Start-sleep -s $minutes

Add-Type -Assembly System.Windows.Forms
[System.Windows.Forms.Application]::SetSuspendState("Suspend", $false, $true)

And now when I run it, I just enter the minutes I want to wait until sleep.

You can run this from the cmd line by writing powershell sleep.ps1.
