Port Replicator Power Overload

If a power shutdown occurs intermittently when PC Card devices are used with a port replicator, suspect an over-current problem. Some PC Card devices use much

power, and if at some point the required power exceeds

the allowed power, a power shutdown occurs. Isolate this problem to a device by removing each device simulatneously and then using the computer under the

same condition as when the power shutdown occurred.

This will determine which device is causing the overload.
