What will u do if you want to let your computer automatically shut down at a certain time?

 

I usually download some software to do this. However, it is not allowed to download or install

 

 anything on my working computer, then can we do this without other software?

 

The answer is yes, I have found an easy tip to shut down ur pc without download anything.

 

For example, you want to shut down your computer on 22:00, u just need do as the following:

 

Click “StartàRun”, then input “at 22:00 Shutdown -s”.

 

Then the “Shut down window” will popup out on 22:00, there will be a 30-seconds countdown

 

and a hint of asking you to save ur work.

 

If you want to shutdown ur computer by countdown, you can input “Shutdown.exe -s -t 3600”,

 

which means your pc will automatically shut down after 60 minutes (3600 means 60minutes)

 

After setting the shutdown time, you can cancel the setting by input “shutdown -a” as well.

That's a good one Hyacinth!   I use it on some old PCs which do not support power management.

If folks run shutdown /?  they'll see other potential uses:

 Usage: shutdown [-i | -l | -s | -r | -a] [-f] [-m \\computername] [-t xx] [-c "comment"] [-d up:xx:yy]

        No args                 Display this message (same as -?)
        -i                      Display GUI interface, must be the first option
        -l                      Log off (cannot be used with -m option)
        -s                      Shutdown the computer
        -r                      Shutdown and restart the computer
        -a                      Abort a system shutdown
        -m \\computername       Remote computer to shutdown/restart/abort
        -t xx                   Set timeout for shutdown to xx seconds
        -c "comment"            Shutdown comment (maximum of 127 characters)
        -f                      Forces running applications to close without warning
        -d [ u ][p]:xx:yy         The reason code for the shutdown
                                u is the user code
                                p is a planned shutdown code
                                xx is the major reason code (positive integer less than 256)
                                yy is the minor reason code (positive integer less than 65536)

huh...i thought you are talking about unplug power source to shutdown ... to me ... scheduled shutdown is kinda software shutdown ... perhaps you mean no 3rd party software needed ... anyways...good share

Neat.  Any chance there is an argument or a different function that would pull off the same thing with sleep?

You could try to make a shortcut like this:

%windir%\system32\rundll32.exe PowrProf.dll SetSuspendState

Here's log-off:

%windir%\system32\shutdown.exe -l -t 01 -f

Here's a shortcut to lock your PC:

%windir%\System32\rundll32.exe user32.dll,LockWorkStation

Hah, great. Then, my PC can shut down automatically just like TV set.

Most PCs will shut-down...but the ability to go in to hibernate or sleep modes depends a good deal on your PC hardware.

See my experience.

with  rundll32 Powrprof.dll,SetSuspendState 
 

you can't guarantee it will always work. As you are passing "", "", "". to a function that expects values.

in addition If the ForceFlag parameter is TRUE, the system suspends operation immediately; if it is FALSE, the system requests permission from all applications and device drivers before doing so.

as papah said it depends a good deal on your hardware !   lol

Good points.  

I found that even though my hardware supported it, that I had to use that dumpo.exe utility to make it happen.

Apparently there is a newer utility called “sleeper.exe” that is part of the Windows Driver Development Kit.  I have MSDN access.  I DL’d but didn’t want to install 2.5GB to get it.

 

WOW, great info, many thanks to all here, esp. Hyacinth

The thing is my PC gets awfully slower these days, and it takes a long time to shut down. Finally I will have to shut it down in Project Explorer. Lol after I set up the time to turn off my PC as you said, It doesn't bother me any more, thanks a lot.

great!

then i can fall in sleep without any problem while watching movies on my pc

very nice tip

thanks a lot for sharing
