System will not shut down when instructed to do so by the operating system- It bypasses shutdown and simply reboots back into the O/s

On mine, until an electrical storm, was controlled through my computer via USB. Now, it shuts down in 5 seconds. I'm sure it's the thermistors, but I don't have time. Also, check for timing circuits.

depending on your operating system...for most windows go to start/look for the shutdown tab but instead of using shut down. Select "RESTART". Then sit back and let your computer reboot.

Hi,

To reboot the desktop machine, kindly press the power on button for few seconds / small button(reset) below the power button to reboot the computer.

If its laptop follow the below steps

Determine what operating system it uses. Finding out what operating system your laptop uses will let you know what key combo (such as "Ctrl+Alt+Delete") can exit you from usage and trigger a reboot or shutdown.

Try and reboot using the operating system. Attempt to use the key combination that will allow you to exit from the operating system and restart the laptop. Be patient, as it may take some time if it has locked up.

Hold down the power button. If the operating system's answer to the rebooting will not work, find and hold down the power button of the laptop. This should cause the device to shut itself off. You'll have to press the power button again to power it back on, completing the reboot.

Unplug from the wall and remove the battery. If restarting via the operating system and the power button do not work, unplug the laptop from the wall outlet, and remove the battery from the laptop. This will cause it to power off immediately.


Allow time to reboot. Give the laptop time to cool down before you power it back on if you had to do this manually. A few seconds should do unless you have additional problems.

Hi,

Few steps to restart you laptop, I would suggest not to restart often since it will degrade the hardware resource.

• Determine what operating system it uses. Finding out what operating system your laptop uses will let you know what key combo (such as "Ctrl+Alt+Delete") can exit you from usage and trigger a reboot or shutdown.

Else Try:

Windows start > there's a small arrow(pointing RIGHT) in the left bottom > click it and u will get ALL the Power House Options there at your Click(sleep,hibernate,shut down,RESTART,....)

When turning your laptop on, before Windows starts booting, a splash screen appears first (usually with the logo of the manufacturer). Look on the splash screen (usually at the bottom) for a key (usually F10 or F11), assigned for System Recovery CD/DVD with the laptop. or 1.Press the start button from the start menu depending on your operating system(win 2000,xp) 2.Press Ctrl+Alt+delete combination from the keyboard. 3.If you have a power button on your laptop keyboard,it could also be useful by pressing and hold it down for few seconds N.B: "Ctrl+Alt+Delete" can exit you from usage and trigger a reboot or shutdown.

All the Best!

Your pc might be affected with some kind of viruses or torjans so you may format your computer or clean it by a good antivirus
thanks

Reboot is another term for restart.
You can shut the system off, and then turn it back on again after a few seconds.
Or you can have the operating system do it for you, using the restart option instead of the shutdown (turn off) option.

Best to format and reinstall a fresh copy of your operation system.

windows and the bios needs to know that the operating system can be shut down through windows, so when you go into the F2 or Del on boot up, go into advanced cmos setings and look for ACPI and make sure it is enabled. This sets the motherboard to support shutdown. Save and exit settings and reboot. Now go to control panel>performance and maintanance>power options and set the correct instruction for shutdown to shut the pc down. Remember evertime you remove the cmos battery or reset with jumpers you have to reset date and time and anything else you have changed to suit your set up
