10. If diagnostic errors appear, replace the port replicator
or the diskette drive. If the problem remains after the
replacement, replace the system board.
11. If power problems appear only when the port
replicator is used, replace the port replicator.
Power overload: If power shutdown occurs
intermittently when PC Card devices are used through a
port replicator with PC Card slots, suspect a problem with
over-current. Some PC Card devices use more power; if
the maximum use of each device occurs simultaneously,
the total current will exceed the limit, causing a power
shutdown. Isolate this problem by removing one of the
devices, and using the computer under the same condition.
If a power shutdown occurs, you have found the cause of
the problem. If not, do this procedure for all the other
devices until you determine the cause.
