What is Windows 8.1 command for POWER OFF?

April 3, 2015 at 11:07:57
Specs: Windows 7, i7 4930K / 32GB RAM
I'm running Windows 8.1 on a high-end computer. Sometimes the OS doesn't shut down completely. It seems the very last part of the shutdown operation doesn't always happen. I've tried all the obvious ways of fixing this. And now I'm finally in the command prompt, trying to manually shut down the computer COMPLETELY.

The way you're supposed to be able to shutdown Windows 8.1 is to just choose "SHUTDOWN," but that doesn't always work. What happens is, the OS apparently shuts down, the screen goes black, but the light on the case is still lit, and the fans are still running. I have to hold the button on the case down for about 7 or 8 seconds before the light finally goes out... and the fans turn off.
And when I start the computer again, I get an OVERCLOCKING FAILED message, and I have to go into the BIOS and out again without doing anything, before Windows will startup normally.

And here's the strange part! When I uninstall a program, or choose a different path in shutting down, (or anything else), in an effort to fix things, the computer acts as if the problem went away! Shutdown is normal for a short time. But after maybe 5 or 6 normal shutdowns, the problem begins to return! MINI shutdown hangs occur... where the light on the case stays on... but I don't have to hold the button down for a period of time to get the light to go out. When I depress the button, it goes out immediately! And there's no OVERCLOCKING FAILED message at startup! Windows starts normally.

My question is:
What is the DOS command for POWER OFF? Even when I tried to shutdown in the command prompt, the same problem occurred. That very last part of the shutdown procedure doesn't happen.

I used,
-l for log out,
-s for shutdown
-t 0 for the number of seconds that should go by before anything happens.

The first thing I type is...
shutdown ...

Then I use the other commands.

And the same old thing happens. Maybe about 5, 6, of 7 normal shutdowns, then some MINI hangs.

But so far, this time it's different. I've gotten nothing but normal shutdowns, and MINI shutdown hangs. I'm beginning to think that maybe it's what seems to be the very last part of the shutdown procedure that I need to find a command for. Does anyone know the command for turning off the power to the computer???

I admit the I'm only a YELLOW-BELT GEEK but I really wanna figure out how to get my shiny new computer to completely shutdown!!!!

Any help with this will be very much appreciated. :)

Shut down problems have long been evident with various flavours of windows. Sometimes a given installation will simply shut down OK, and sometimes not... Usually there is fix for this from M$-land...

This is one such discussion - and may help/apply in your situation?

And this from another site:

Often the fix for one version of windows will apply to another; particularly if the two versions are next to each other in the windows family (e.g. win-7 and wind-8x; or XP and win-7 etc...)

Are you using Skype by any chance? That can hang up quite a while.

Have you tried Slide to Shutdown from this path?:
"C:\Windows\System32\SlideToShutDown.exe"
You then have to click the screen on the "blind" or hit Enter (anywhere) but if it should work out better it can be very easily automated with AutoHotkey. I've found this shutdown gives the fastest boot afterwards.

Both going through the Metro GUI and running anything from the Command Prompt is still going to call ExitWindowsEx().

Honestly, it sounds like you need new chipset drivers or new motherboard firmware.

OK, I forgot to tell you that I'm also running Classic Shell along with Win 8.1 ...

I don't understand what you mean when you explained how to use the
"C:\Windows\System32\SlideToShutDown.exe" ...

OH, Skype is on my computer but I never use it. Should I uninstall it?

Up to you whether you uninstall it but if you prevent it starting with Windows it will no longer be implicated in shutdown unless you've been using it (manually). To get to the setting open Skype then go to Tools > Options and you will see the check box there. You can then Quit Skype (rather than sign out) by right clicking the icon.

Skype is uninstalled. And I've been trying out "shutdown -s -f -t 0," and something very strange seems to be happening. I've been shutting down over and over again since this afternoon, and for all that time I got no FULL HANGS! Only a mix of normal shutdowns and MINI HANGS. With the MINI hangs, the light stays on but all I have to do is just tap the button and the light goes out immediately... and there's no OVERCLOCKING FAILED message at startup. But the strangest thing is, now when I go back to just clicking on "SHUTDOWN" in the Classic Shell Start Menu,(where I got all those FULL shutdowns), the same thing seems to be happening! No FULL SHUTDOWN HANGS! Is that code I typed in, going farther than I think? Is it affecting stuff I never thought it could?

Anyway, I'm still not satisfied with what's going on, still. Sometimes I get the MINI's and sometimes I don't! Isn't there a command for turning the light on the case out???? That would be shutting off the power to the computer. That command might fix everything! (Couldn't it?)

Just noticed your #6. All I meant was you follow that path and create a shortcut to SlideToShutDown.exe and when clicked this will produce a blind that comes half way down the screen. You then either hit the Enter key or click on the blind to shut down. I've gone further and automated it entirely - double click from a desktop icon.

In your #9 I assume you mean the command "shutdown -s -f -t 0". Well the -f forces programs to shutdown if they are hanging. It is likely that which has stopped the hangs. If you want a list of those "switches" then go to Command Prompt, type shutdown /? (hit Enter) and it will list what all of them do. In Command Prompt /? is equivalent to Help.

Difficult to see why the other issues have vanished though - you must have blasted them away somehow LOL.

I don't understand why the FULL hangs seem to've disappeared either. When I started using that string, did it effect more then we know? Or maybe it's that other affect... meaning... whenever I do something, (anything), to try and fix the shutdown thing, the problem seems to go away for a while. And this is the biggest thing I ever did. So maybe it just appears that the problem is gone when I shut down where I use do, (and the problem was always there).

I just wondered if there's a command that turns off the power to the computer! That's the only thing left! And if there isn't, can't one be written? Unfortunately, my valiant attempt to become a programmer failed when my software broke... so I can't write something to turn of the power on the computer. I'll have a look at the command list to see what I can find.

Thanx for your cool response. :)

I didn't make it clear enough. I'm not so surprised that the command helped the full hangs but have a job to see why it made any improvement to the classic shell shutdown or the overclocking message.

Sorry, don't know any other commands that would help.

Yeah. Well the real mystery might be that in the past, after I did stuff to try and correct the problem, it seemed to go away for a bit........ But then the MINI hangs started. And then, the FULL hangs! So this time, I may've done something really big? And the problem just SEEMS to've gone away in the Classic Shell Start Menu... and it seems to be staying away for a longer time than usual. But I'm betting things will go back to the way they were again soon. If they return in the command prompt or in RUN, then... I just donno what to do!

Actually, I take back what I said. It sounds like your video drivers or video card is bad.

OK, this time, I was fooled! Before, I knew the problem only goes away for a short time, and then the MINI hangs return, and then the FULL hangs. But this time it didn't happen for a much longer time... and I was actually fooled! This morning, Easter, there was the rebirth of the FULL shutdown hangs! So the -f command did nothing. The problem lies elsewhere!

I hear that "some installs" of Windows 8.1, 8, and 7 have shutdown problems. Maybe I need to do a clean install of Windows 8.1. I'm worried about my files though... and I don't think I have the Windows 8.1 disk.

Is your computer home built/assembled - which means you used a retail or "full"OEM disk to install windows; or is it one you bought from where/whomever?

If the latter then make and model would be rather useful at this time..

Most "pre-assmebled/bought systems have a recovery partition on the drive (somewhere). Some may (still) provide a recovery disk set; although generally that's rare these days. Nonetheless when such systems are sold the advice coming with them is to make one's own recovery set "immediately" - for situations such as you are now considering... So what make/model; did you receive any disks with with; did you make a recovery set; and do you know if there is recovery partition?

As regards safeguarding files.. Simply copt them to DVD and double check the copies are truly accessible on at least one other working system,s; and if possible make a second set of disk too. And equally if possible copy them to an external hard drive as well; and verify copies are OK as above. Two different types of media for file safe keeping/storage is generally safer than one...

Also find your installation key... If a bought system then it's likely on a label on the back or base of the system. If it's OEM (and those letters may included in it) then that "key" can be used with any OEM disk and you simply apply "your key" at the appropriate time during setup etc.

Magic Jellybean may find the "keys" for all OS/apps/utils etc currently installed; as will Belarc Advisor - the latter generates a complete report about the system as is - "keys" included... Useful/wise to print it out and safe keep.

Here's what's happening now! I tried hibernating instead of shutting down. So far it's working fine. But there's something that tells the problem to "hide" after a "change" in the system. And then, after a while, slowly at first, things start messing up... and soon after that, the rather familiar shutdown issue that many people find on their system after it was delivered.

Something probably goes wrong when Win 7, 8, and 8.1 are installed, IN SOME CASES... and a new clean install could correct the problem...............................................
........................or not! Maybe the OS have to be reinstalled over and over until it finally works right?
