                        POWEREXEC OS/2 SUSPEND/MOUSE GHOSTING

    PROBLEM:       The following hardware and software incompatibilities exists:

                    1) While under OS/2, the PowerExec hangs (locks up) upon
                       returning from the Suspend mode.

                    2) Under standard OS/2 configuration, mouse movement causes a
                       "ghosting" (shadow) to the right of the mouse pointer.

    CAUSE:         Incompatibility with the OS/2 RGB (204, 204, 204) color
                   combination using a Hitachi LCD panel.

    SYSTEMS
    AFFECTED:      PowerExec 486SL/25 Mono and Color.

    SOLUTION:      1) Use IBM's OS/2 Corrective Service Pack, version 2.11.  This
                      pack can be downloaded from Compuserve at

                            Go IBMSERVPACK

                   It can also be shrink-wrapped as version 2.11, or by
                   contacting IBM.

                   2) Replace the Hitachi LCD panel with the NEC LCD panel.  Part
                      Numbers are as follows:

                             221020-001 Mono
                             221021-001 Color
