Port Replicator Checkout

1.  Power-off the computer.
2.  Remove the failing devices from the replicator.
3.  Unplug the AC adapter from the replicator, if attached.
4.  Remove the port replicator from the computer.
5.  Reconnect the failing device directly to the computer.
    (If another device occupies the connector, remove it first.)
6.  Go to 'Running the Diagnostics' and run the diagnostics.
7.  If the advanced diagnostic device test does not find an error,  suspect a problem with the port replicator
8.  Power-off the computer and reconnect the port replicator.
9.  Power-on the computer and run the following advanced diagnostic tests:
   •  Serial port test with the wrap plug installed on the port replicator.
   •  Universal serial bus test with the test USB test-cable.
   •  Parallel port test with the wrap plug installed on the port replicator.
   •  FDD-2 drive test on the failing device with a scratch diskette.

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 using the port replicator, replace the  port replicator.

Port Replicator Power Overload

If power shutdown occurs intermittently when using PC-Card devices are used through a port replicator with PC Card slots, suspect an over-current problem.

Some PC-Card devices use more power, if the maximum usage of each devices occurs simultaneously, the total current will exceed the limit, thereby causing a power shutdown.

Isolate this problem by removing one of the devices, and use the computer under the same condition, and see whether a power shut down occurs.
Do this procedure for all devices then determine the cause.
