How to Reboot a laptop?

1.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. 2.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. 3. 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. 4. 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. 5. 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.

Basically, you shut the computer down. Procedure for that depends on the specific operating system. Operating system is what makes a computer do things. Even the thing the loads the main operating system for a given computer is a small operating system in itself. For example, the thing that loads Windows or Linux up is called BIOS, and that stands for Basic Integrated Operating System. Once you exit all the operating system(s) you may as well shut down the machine (if it does not shut down by itself.)
