When power is turned on, the hibernation history of the

Port Replicator Power Overload: If power shut
downs occur intermittently when using PCMCIA-2 devices
via a port replicator, suspect an over-current problem.
Some PCMCIA devices use more power; if the maximum
usage of each device occurs simultaneously, the total
current will exceed the limit, thereby causing a power shut
down. Isolate this problem by removing one of the
devices, and use the computer under the same condition
to see whether a power shut down occurs. Do this
procedure for all devices, then determine the cause. Use
of the larger AC Adapter (50W, optional) is recommended,
if one is not yet in use.
