    ASCENTIA 900N/910N LOSE NETWORK CONNECTION WHEN THE LID IS CLOSED

    PROBLEM

    When the Ascentia 900N goes into suspend, the network connection established
    via I/O ports is broken.

    CAUSE

    This is a normal function of the Ascentia 900N/910N design.  When system
    suspend is forced via a lid closure (without external CRT attached), via the
    + keystroke, or via a dangerously low battery level (battery fail),
    suspend is initiated without checking for system activity.

    When the Ascentia 900N and 910N are in suspend, all devices are put in their
    lowest power state.  This means that the serial and parallel ports are turned
    OFF.  Also, the CPU is stopped.  As a consequence, even if the serial and
    parallel ports were kept alive, the CPU would not be available to service any
    network connection, and hence the connection would be lost anyway.

    SOLUTION

    If a network connection must be maintained,

    DO NOT close the lid (unless operating on CRT),
    DO NOT press +,
    DO NOT let the battery discharge to a dangerously low level.
