When power is turned on, the hibernation history of the boot record on the hard disk is recognized and system status is restored from the hard disk to resume operation. Port Replicator Power Overload: If intermittent power shut-downs occur while using PCMCIA-2 devices through a port replicator, suspect an over-current problem. Some PCMCIA devices use too much power, and if the maximum usage of each device occurs simultaneously, the total current could exceed the replicator limit, thereby causing a power shut down. Remove each device one at a time and repeat the sequence until problem fails to return. Ten determine the cause. 330 IBM Mobile Systems HMM
