                       LOGITECH MOUSE LOCKS UP AFTER SUSPEND

    PROBLEM:     When the Ascentia 950 (or any other notebook that
                 incorporates Advanced Power Management) resumes from a
                 suspended state, the mouse freezes.  The computer and
                 keyboard are operational; only the mouse is affected.

    CAUSE:       Logitech's mouse drivers, versions 6.43 and earlier, will
                 exhibit this symptom on any machine using Advanced Power
                 Management.  When the computer enters and resumes from a
                 suspended state, the driver does not wake up the mouse.

    SYSTEMS AFFECTED:
                 All AST Portable Systems that incorporate Advanced Power
                 Management.

    SOLUTION:    Install the latest Logitech mouse drivers (version 6.5 or
                 above).  Updated drivers may be obtained by contacting
                 Logitech Technical Support at (510)795-8100.
