Sleeping a computer via batch file in Windows 7

Question

I want to make a batch file that will sleep my computer after a period of time.

The closest thing I have found is placing it in standby, but seems to work differently than the sleep button on my keyboard (longer bootup, doesn't wake on mouse click). Any ideas? Would it be easier in Python or C#?

The less then ideal technique mentioned above is calling this in the cmd prompt:

Rundll32.exe powrprof.dll,SetSuspendState

Answer 1

Simply command

rundll32.exe powrprof.dll,SetSuspendState

Does system hibernate, but if you write this:

rundll32.exe powrprof.dll,SetSuspendState 0,1,0

And turn off hibernation with command:

powercfg -hibernate off

Now your system will go asleep, and will wake up on mouse move if selected a device for it (scroll down to learn how).

Batch a timer:

timeout /t 1200
rundll32.exe powrprof.dll,SetSuspendState 0,1,0

Where 1200 is seconds, which mean after 20 minutes batch will run sleep command.

Optionally you can prevent canceling countdown (if you press any key in batch window):

timeout /t 1200 /nobreak
rundll32.exe powrprof.dll,SetSuspendState 0,1,0

Little HOWTO about waking up with mouse:

Go to: Start -> Control Panel -> Mouse.

In the Mouse Properties window, click on the Hardware tab and select your mouse from the list of devices. Normally, there will only be one mouse listed here but that will depend on the hardware you have connected to your computer. When you have selected your mouse from the list, click the Properties button.

Now in the Properties window for your mouse, click on the Change Settings button on the General tab.

In the window that opens, click the Power Management tab and check the option titled Allow This Device to Wake The Computer. Click the OK button on this window and click the OK button on the Mouse Properties windows that is still open. From now on, you can wake up Windows 7 from sleep mode by clicking a mouse button or moving the mouse around.

Answer 2

Working Solution!
I had to use the PsShutdown utility to allow proper sleeping (primary issue is SetSuspendState does not allow wake timers to wake up the machine). My batch file to sleep is 1 simple line:

PsShutdown -d -t 2

Answer 3

shutdown /h

will hibernate the computer (not sure about suspend though).

Answer 4

.NET to the rescue. This solution put computer to sleep without need of changing PC config (turning off hibernation). Run this command in batch:

powershell.exe -command "Add-Type -AssemblyName System.Windows.Forms; [System.Windows.Forms.Application]::SetSuspendState([System.Windows.Forms.PowerState]::Suspend, $false, $false)"

You can use either ::Suspend for sleep, or ::Hibernate (which the way the other answers work). Documentation for SetSuspendState.

As System.Windows.Forms namespace is not loaded by default (it does in Powershell ISE), you need to load assembly for that at first.

Answer 5

Just create a batch file and insert the following lines:

7200 = 2 hours

@echo off
timeout /t 7200 /nobreak
powercfg -h off
rundll32.exe powrprof.dll,SetSuspendState 0,1,0
powercfg -h on

Answer 6

You may try SetSystemPowerState to avoid having to disable Hiberanate.

rundll32.exe kernel32.dll,SetSystemPowerState

Note that adding 1,0 or 1 0 or even doing Rundll32.exe powrprof.dll,SetSuspendState 0 0 1 or Rundll32.exe powrprof.dll,SetSuspendState 0,0,1 that the arguments (0,0,1) mean NOTHING.

The powrprof.dll,SetSuspendState does not parse rundll32 style arguments and thus ignores them. That is why you have to disable hibernate.

Answer 7

This question has already been answered.

powercfg -h off & start /min "" C:\WINDOWS\System32\rundll32.exe PowrProf.dll,SetSuspendState 0,1,0 & ping -n 3 127.0.0.1 > nul & powercfg -h on & exit
