Abstract

The present invention provides an electrical device having a power saving mode, a sleep mode, and a run mode of an OS system. A modality switch controls an on-off of the battery module and the OS system for achieving to switch between the power saving mode and other modes. The power saving method mentioned above can apply to the shipment and the storage of the electrical device to reduce the power consumption of the battery.

Claims (38)

1. An electrical device, comprising:

an OS system module;

a battery module;

a power saving module coupled to the OS system module and the battery module, comprising:

an electrical switch, for controlling the battery module to or not to supply power for the OS system module to work;

a first voltage pull element, electrically connected to the battery module;

a second voltage pull element; and

an inverter, electrically connected to the electrical switch; and

a switch module for controlling the power saving module to make the power saving module control the battery module to or not to supply power for the OS system module to work, comprising a modality switch for controlling the electrical device to be switched to different powering modes;

wherein under an initial situation, turning off a power saving mode by actuating the modality switch to an open position to drive the electrical switch open, then using the inverter and the first voltage pull element to enable an electrical conduction pathway connection for the battery module to supply power for the OS system module to work for making the electrical device under a run mode;

then, turning on the power saving mode by actuating the modality switch to a close position to drive the electrical switch close, then using the inverter and the second voltage pull element to disable an electrical conduction pathway connection to cut off the power supply from the battery module to the OS system module to disable the OS system module;

5. A power saving method for an electrical device comprising the following steps of:

controlling a battery module to or not to supply power for an OS system module to work using a switch module and a power saving module;

determining if there is an electrical conduction pathway connection from the battery module to supply power for the OS system module to work;

turning off a power saving mode if there is an electrical conduction pathway connection; and

turning on the power saving mode if there is not an electrical conduction pathway connection;

wherein the power saving module further comprises: an electrical switch, for controlling the battery module to or not to supply power for the OS system module to work; a first voltage pull element, electrically connected to the battery module; a second voltage pull element; and an inverter, electrically connected to the electrical switch; the switch module further comprises a modality switch for controlling the electrical device to be switched to different powering modes;

wherein under an initial situation, turning off the power saving mode by actuating the modality switch to an open position to drive the electrical switch open, then using the inverter and the first voltage pull element to enable an electrical conduction pathway connection for the battery module to supply power for the OS system module to work for making the electrical device under a run mode;

then, turning on the power saving mode by actuating the modality switch to a close position to drive the electrical switch close, then using the inverter and the second voltage pull element to disable an electrical conduction pathway connection to cut off the power supply from the battery module to the OS system module to disable the OS system module;

and when the modality switch is pressed under the power saving mode and set into a LOCK condition, the electrical device is under a sleep mode.

6. A power saving method for an electrical device, the electrical device comprising an OS system module, a battery module, a power saving module coupled to the OS system module and the battery module, and a switch module coupled to the power saving module, the power saving method comprising the following steps of:

controlling a battery module to or not to supply power for the OS system module to work using the switch module and the power saving module; and

determining if there is an electrical conduction pathway connection from the battery module to supply power for the OS system module to work;

turning off a power saving mode if there is an electrical conduction pathway connection; and

turning on the power saving mode if there is not an electrical conduction pathway connection;

wherein the power saving module further comprises: an electrical switch, for controlling the battery module to or not to supply power for the OS system module to work; a first voltage pull element, electrically connected to the battery module; a second voltage pull element; and an inverter, electrically connected to the electrical switch; the switch module further comprises a modality switch for controlling the electrical device to be switched to different powering modes;

wherein under an initial situation, turning off the power saving mode by actuating the modality switch to an open position to drive the electrical switch open, then using the inverter and the first voltage pull element to enable an electrical conduction pathway connection for the battery module to supply power for the OS system module to work for making the electrical device under a run mode;
