Apple Duo 270C manual Restarting a computer that’s already on

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.

nTo restart your computer, choose 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.

nPress the x (Command), Control, and Power On keys at the same time.

When pressed at the same time, these keys turn the computer off and back on. This key combination produces the same result as pressing the reset switch on other Macintosh models. The PowerBook Duo does not have a reset switch.

Restarting the computer this way does not affect your RAM disk (if you created one) or its contents.
