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.
