Also where do I put the time? Shouldn't there be an XX or 00 like in the shutdown command? Is what I am typing into cmd prompt wrong?

Hello LongApple,

Firstly, it's 'rundll32.exe'. Not 'rund1132.exe'.

Secondly...

Rundll32 is not a command. It is a wrapper program that's purpose is to launch other programs stored within dll files and should never be invoked by the user directly; not through the command prompt, not through shourtcuts.

Forcing Windows to sleep using this method is considered dangerous.


You should instead be using "Control Panel\Hardware and Sound\Power Options\Edit Plan Settings" to choose when your computer sleeps.





If you really want your computer to sleep through a shortcut/command, it's recommended you download PsShutdown from here and create a shortcut to that instead.

A quote from a user at Superuser.com briefly describes Rundll32s problems by invoking Rundll32 this way.

rundll32.exe PowrProf.dll,SetSuspendState is not recommended. It is dangerous. (Because it corrupts the stack, as it does not comply with the function signature demanded by Rundll32. Then unforeseeable bad things may happen, as Raymond Chen warns…)

Rundll32 only supports running DLL exports with the following signature:
void CALLBACK EntryPoint(HWND hwnd, HINSTANCE hinst, LPSTR lpszCmdLine, int nCmdShow);It does not support running arbitrary entry points. Since ShellExecute does not have that signature, clearly bad things will happen.
INFO: Windows Rundll and Rundll32 Interface has more info on the rundll32 interface.
If you want to do the equivelent of ShellExecute from the command line, just use start:
C:\>start "C:\Documents and Settings\admin\Desktop\tmp"
