Immediate power shutdown on Vio Desktop

As soon as I push the power button the power shuts down and will not reset until I unplug and wait 30 seconds then it repeats. The power shuts down like a breaker switch does in your house--except no sound.

I would suspect a power supply failure. It is one of the first things to go bad in a computer. From what I understand if the voltage is not correct to the motherboard (power good signal), the MOBO will send a signal back and shut down the power supply. It sounds like a safety feature to keep the MOBO from getting fried. Replace with a higher wattage power supply if you can afford it. But then it could be something entirely different too.

Tip

Safe and easy shut down for regular Desktop users


Hai from Vishu
For Desktop Systems
when all applications are closed user can depress power button once for a second located on front panel of CPU(not the reset button) to initiate shutdown at one go when system is to be shutdown.( Applicable for all P4 cpu ONLY and not for older system where this action shuts down CPU immediately...)

Here's how to create a shutdown shortcut on your desktop


Instead of going to the start menu, choosing shutdown, then waiting for the computer to shut all the programs down, you can create a shortcut on the desktop to do it quickly. You can create a shutdown, restart, or a logoff icon on your desktop which will work a lot quicker than using the usual buttons in the start menu.
Here's how to create a shutdown shortcut on your desktop

1. Go to your blank desktop
2. Right click on a blank space and a menu will appear
3. Choose New from the menu
4. Then choose Shortcut
5. Where it says type the location of the item type in shutdown.exe -s
6. Then press next
7. Now enter a name for your icon. Mine is called SHUTDOWN NOW
8. Press next
9. The Shutdown shortcut will be on your desktop

Different combination you can type in when creating a shortcut to shutdown, restart, or logoff.


Shutdown.exe -s

Shutsdown your computer in 30 seconds and will close all programs and ask you to save all work.

shutdown.exe -r
Restarts your computer in 30 seconds.


shutdown.exe -l
This one will logoff your computer back to the welcome screen where you will need to login again.

shutdown.exe -s -t 1
Shutsdown your computer in one second. the -t 1 tells it how long to wait. (one second in this case) You can put -t 10 or even -t 1120.

shutdown.exe -s -t 15 -c "Goodbye you idiot"
This is my favorite code. It will shutdown in 15 seconds and have a message in the box saying "Goodbye you idiot"
The -c "bla bla bla" stands for a comment.

Notes:

* to stop the computer from shutting down type shutdown /a into the run box located in the start menu..
* -f will force everything to close immediately without asking to save anything.

HP M7357c overheating problem


When the CPU in the computer or laptopoverheats then it will shut down (i.e. thermal overload) and won't boot upagain until it has cooled down. If this is the problem is not fixed then theCPU will eventually fail.
A faulty fan causes this problem or the fan and heat sink assembly are cloggedwith dust.
Check the CPU fan to see if it spins freely, if not replace the fan. If the fan and heat sink is clogged withdust the remove the dust and make sure the vents are clear and dust free. Use acan of compressed air to do this.

I cannot find the shutdown it disappear because of a certain download,now i dont knw how to shut may desktop....plz help i am so sleepy already


Try pushing the power button once, briefly. It should trigger the shutdown sequence. If not, try hitting Ctrl, Alt and Delete at the same time. That should bring up Task Manager. You'll find shut down in there. If that doesn't work either, all you can do is push and hold the power button until it shuts down, usually about 4-5 seconds, or pull the power plug.

Shutdown problems


I assume it is not shutting down. Do a complete reset, unplug computer from wall push power button in for 3-5 seconds, then plug it in and restart the machine. Then let it complete the boot up process then go to start and shut it down again see if it shuts down now. Thanks for the question hope this assists you. John

Acerpower SV PC will Not turn off


More information would help to resolve this issue.

Are you shutting down by selecting Start and shutdown or have you tried pushing the power button on push (not holding the power button)?

Try this:
Press and hold the power button in solidly for about 10 seconds. If it shuts down before you get to 10 just let off the power button. This should work, but may not solve the problem.

If you reboot it and still can not shut down from Windows, hold power button until it shuts down, unplug the power cord and disconnect everything from the computer other than the keyboard, mouse and monitor. With the power plug still unplugged, hold the power button in for about 15 seconds (this resets the power supply and can clear a corrupt BIOS).

Reconnect power and after booting, see if you can shut down from Windows.

If still no go, click Start, Programs, Accessories, System tools and select System Restore.

Follow the prompts and select a bold date back to a time before you had problems shutting down. That should do the trick.

Let me know if you get it fixed or if you need more advice.

Dell Dimension E510 Problem


here are just a few things I would suspect.

One of those windows in the BIOS settings will display all the voltages at spec and the actual voltage. There should not be more than a 10% difference above or below. As you seem unafriad of your computer could you remove the left side and see what the make and model of the power supply is. It should give spec and voltages.

Second is your Cmos battery weak, was it individually packaged and is there a date on it, Try getting one from a different source to make sure you are getting a different lot or try a different brand. Look at the contacts on pc for the battery look for signs of oxidation. Look at the soldering to see if it looks damaged or bad, they can crack or break. Some one with a tester could check them to see if they are good. Of course, make sure you are connecting the battery with the correct polarity. Also, check for a leaky capacitor on the motherboard.
When you are taking out the cmos are you just immediately putting the new one in and then restarting? If so do this instead, unplug from power, remove cmos battery, leave it just like that for at least 30 mins. This allows a good power cycling. Then replace with good new battery (you can have the battery tested for strength) if battery has date codes you can check for freshness, you want to try to get a fresh one, after install of battery, plug in and try it. Sometimes a minimum 30 min power cycling resets things. Also, What else is installed and how much "stuff" is connected to the USB ports but is not self powered? Now the amber light ... Unplug computer, disconnect all usb/monitor/internet, open it, hold power button until green led on the inside on the motherboard turns off, pop out the battery. Plug in computer, hold power button for about 20 seconds (must reset BIOS), let up on power button, wait 10 seconds and push power button. The computer should turn on. Wait for it until activity seems stable (1 min. or so). Push powerbutton to shut off.

If this has worked you have proven that it's not the power supply (it turned on).

Go buy a new battery (CR2032 3 volt). Unplug computer, open it, hold power button until green led on the inside on the motherboard turns off, pop in new battery, plug in (you should notice the power button blinking amber again), hold power button until it stops blinking (about 20 sec....again must reset BIOS), wait 10 sec., push power button. the computer should turn on. Wait for it until activity seems stabe (1 min. or so). Push powerbutton to shut off.

Now, close case, plug in all usb/monitor/internet/etc. Power up computer. You'll get an internal floppy drive error. Push F2 (maybe F1) to get into the BIOS settings and go to "drives" and turn off the internal floppy. Save and exit. The computer should boot properly now.

This seems to be a big problem with the e510, my theory is that this one small battery is the root of most of these failures (as these computers usually fail after 1-2 years), not the power supply or the motherboard (heck, when you replace the motherboard it comes with a new one of these batteries...a several hundred dollar piece of hardware, with a $5 battery that will actually fix it). Those are a few things to look at for now.

Power light blinking yellow after sitting a while


Unplug computer, disconnect all usb/monitor/internet, open it, hold power button until green led on the inside on the motherboard turns off, pop out the BIOS battery (looks like a big watch battery and use a small flathead screwdriver to depress the spring lock on one side), plug in computer, hold power button for about 20 seconds (must reset BIOS or something), let up on power button, wait 10 seconds and push power button. The computer should turn on. Wait for it until activity seems stable (1 min. or so). Push powerbutton to shut off.
