  <div class="attr SUMMARY">
The Auto Power On/Off Control Panel lets you set your Macintosh computer to power ON or OFF at a pre-determined time, on a daily basis or for one particular day. It also has a check box labeled &quot;Automatically restart after power failure.&quot; If you check this box and the power goes off, the computer will automatically restart. This control panel first appeared with the Macintosh Quadra 840AV computer in July, 1993.<BR>
<BR>
The Auto Power On/Off Control Panel supports Macintosh computers that use the soft power off (in other words, systems that do not require you to turn the switch off) and the Cuda Microcontroller chip.<BR>
<BR>
Additionally, the Control Panel works with older soft-power capable Macintosh systems that have a version of the Motorola 68HC05 microcontroller chip. Examples of these systems include the Macintosh IIsi, IIvx/IIvi, and the Color Classic.<BR>
<BR>
