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.
