Port Replicator Power Overload:
If intermittent
power shut-downs occur while using two or more PCMCIA
devices with a port replicator, suspect an over-current
problem. Some PCMCIA devices use more than the
recommended maximum power. If the maximum usage for
each device occurs simultaneously, the total current can
exceed the replicator power limit, thereby causing a power
shut down. Isolate this problem by removing one of the
devices and using the computer under the same condition
to see whether a power shut down occurs. Do this
procedure for all devices, then determine the cause.
