Apple 145 manual Restarting a computer that’s already on, Choose Restart from the Special menu

Restarting a computer that’s already on

You need to restart your computer—turn it off and back on again immediately—when you want to make certain changes to your control panels, use a newly installed system software file, or start up the computer from a different disk.

mChoose Restart from the Special menu.

When you choose Restart, the computer prompts you to save your work, closes all open programs, and restarts itself.

Choosing Restart does not affect your RAM disk (if you created one) or its contents.

You also need to restart if you see a “system error” message on the screen (indicating a temporary software problem). In this case, use the trackball to click the Restart button that appears.

Restarting a computer that can’t be turned on normally

If your system crashes (a rare event resulting from temporary software problems), or if a computer with a properly installed and charged battery does not respond when you try to turn it on, you should be able to restart it using one of the methods described in this section. Try them in the order given. All these methods will cause you to lose any work you have not saved.

mPress and release the reset button.

You can press the button with a pen, a paper clip, or a similar object.

Restarting the computer with the reset button does not affect your RAM disk (if you created one) or its contents.
