                             POWEREXEC NOT SMARTSLEEPING

    PROBLEM:       The PowerExec will not go into SmartSleep mode if one of the
                   following conditions exist;

                   Resume On Modem Ring is enabled under System Setup.
                   Resume On Schedule is enabled under System Setup.
                   External monitor is connected.
                   Simultaneous Video option has been changed since last cold
                   boot.

    CAUSE:         When SmartSleep is activated, data in system and video memory
                   is stored to the hard disk and the system is turned off.  To
                   resume operation from SmartSleep, the power switch must be
                   used to turn the system on.

                   External hardware that can be physically connected to the
                   PowerExec such as modems and monitors do not support a
                   smartsleep feature.

                   This is why there is a SmartSleep abort built into the
                   PowerExec for the above conditions.

    SYSTEMS
    AFFECTED:      All PowerExec SL systems.

    SOLUTION:      Disconnect or disable the condition that prevents the system
                   from going into SmartSleep.
