                       PREMIUM EXEC 386SX/20 AND BATTERY WATCH

    PROBLEM:       When using a Microsoft PS/2 mouse connected to a Premium Exec
                   with MS-DOS 5.0 and Battery Watch software, the mouse cursor
                   will behave erratically when using the mouse in applications
                   such as the MS-DOS Shell, Central Point PC Shell, etc.

    CAUSE:         This problem is caused by a conflict between Battery Watch and
                   the Premium Exec keyboard controller.

    AFFECTED
    SYSTEMS:       Premium Exec systems shipped with the Traveling software
                   Utilities disk (part number 910413-032).

    SOLUTION:      AST Portable Systems Engineering has determined that Battery
                   Watch will not be upgraded to resolve this problem.  As a work
                   around, AST suggests either attaching the mouse to the serial
                   port using the appropriate PS/2-serial adapter or removing
                   Battery Watch from the systems AUTOEXEC.BAT file.
