摘要
A power saving device is configured in an all-in-one PC and has a power module expandably composed of a plurality of Ni-MH cells linked up either in series connection or in parallel connection. When an external alternating power provides power supply for the PC, a charging circuit of the power saving device charges the power module. When the alternating power is out or the PC is operated to enter a power saving mode, a controller of the power saving device notifies the PC to enter the power saving mode, while the power module provides power for the memory and memory controller of the PC with low power consumption. The all-in-one PC consumes little power while in power saving mode and is capable of restoring to its normal mode in short time. The power saving device enhances the all-in-one PC with features of instant-on, long-time standby, and backup power provision.
