A power-saving device is arranged in an integrated molding computer, a plurality of nickel-hydrogen batteries can be extended for being used in the power-saving device and can be connected in series or in parallel to form a power supply module, when the exterior AC power supply of the computer is used for stably supplying the power, a charging circuit of the power-saving device can charge for the power supply module simultaneously. When the exterior AC power supply is powered off or the computer is operated to be in the power-saving state program by the operator, a controller of the power-saving device can notify the computer to enter into the power-saving state, and the power supply module is used for supplying the low electric power to a main memory of the computer and a memory controller to enable the computer to have ultra low power consumption under the power-saving state and enable the computer to recover to the normal working state under the self-power-saving state rapidly. The utility model can provid
