============================================================================= AST RESEARCH, INC. TECHNICAL BULLETIN #0756 06-01-92 ============================================================================= 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.
