TOPIC


    My Power Macintosh 7200 has locked up (the screen is frozen), and it appears that the only way to reset the computer is to disconnect the power cable from the back of the computer. Do I have any alternatives?


DISCUSSION


    There are several methods for interrupting or resetting your computer.


    Interrupting your computer
    ==========================

    Interrupts are used by Macintosh software programmers when writing applications and debugging them. An interrupt produces a blank dialog box on the Macintosh screen. Programmers can then type codes to obtain the response or information they require from the Macintosh.

    You can interrupt your computer by pressing the keyboard shortcut Command-Power.


    Resetting your computer
    =======================

    Resetting the computer is the same as disconnecting and reconnecting the power from the back of the computer.

    You can reset your computer in one of two ways:

    Keyboard shortcut
    -----------------
    Pressing the keyboard shortcut Command-Control-Power restarts your computer.

    Power button
    ------------
    Pressing the Power button on the front panel of your computer shuts your computer down.

    If you press the Power button during startup, before all the extensions and the Finder load, your computer will shut down immediately. If you press the Power button after the desktop appears, the computer shuts down by first closing any open applications and then performing a shutdown. This is the same as choosing "Shutdown" from the Special menu.


    When these steps do not work
    ============================

    If these steps fail, it may be necessary to disconnect the power from your Macintosh. You can turn off the power to your computer at your surge suppressor, power strip, or by removing the power cable from the back of your computer or at the outlet.
