IBM ThinkPad 380XD Hardware Maintenance Manual

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 simultaneously and then
using the computer under the same condition as when the
power shutdown occurred. This will determine which
device is causing the overload.
