ABSTRACT:
A computer includes a dual mode power supply that includes a main voltage converter and a standby voltage converter. The main voltage converter generates a main operating voltage at a normal operating current. The standby voltage generator generates a standby voltage at a standby current. The power supply outputs a dual mode output that includes both the main voltage and the standby voltage. The standby current is less than the normal operating current. The computer includes a host processor, a memory array, and a wake-up device. A power management device is coupled to the host processor and receives at least the standby voltage. The dual mode output from the power supply is input to the wake-up device and the memory array to allow the computer to be placed in a power saving mode by terminating supply of the main voltage. While in the power saving mode and receiving only the standby voltage, the wake-up device can wake-up the computer.
