Embodiment Construction

[0032] The present invention provides an embedded electronic device with a power-saving function operation. The part of the power-saving function referred to here means that after the embedded electronic device enters the power-saving mode operation, it can use a more power-saving method to update the power state of the battery used by the embedded electronic device, so as to achieve the effect of reducing battery power consumption during the updating process.

[0033] see next image 3 , which is a functional block diagram of an embedded electronic device according to a preferred embodiment of the present invention. The embedded electronic device 2 described in this embodiment refers to a device that obtains power supply through a battery 24, such as a notebook computer, a personal digital assistant, a portable navigation device, etc., and the above-mentioned devices are only used for Other types of electronic devices are illustrated and may still be included. The embedded ...

Abstract

The invention relates to an embedded type electronic device with an electricity-saving function and an electricity-saving method thereof. The embedded type electronic device comprises an operation system and a microprocessor, wherein the microprocessor is used for detecting the electric quantity of a battery and outputting an interrupt signal to the operation system when the electric quantity of the battery is equal to warning electric quantity. After the operation system receives the interrupt signal, the operation system can wake up the embedded type electronic device in an electricity-saving mode and update the state of the battery. Therefore, the invention can reduce the frequency of updating the state of the battery so as to reduce the electric quantity consumption of the battery and achieve the electricity-saving effect. Under the operation of the same time range, the times of updating the electric quantity of the battery of the invention are obviously less than that of a traditional method.

Description

technical field [0001] The invention relates to an electronic device, in particular to an embedded electronic device capable of updating battery power in a power saving mode and a power saving method thereof. Background technique [0002] For the embedded electronic device, when it is not operated for a period of time, it usually enters the functional operation of the power saving mode. In the time range of the power-saving mode operation, in order to reflect the status of the battery power, the embedded electronic device needs to execute a battery power update procedure. [0003] see next figure 1 , which is a functional block diagram of a traditional embedded electronic device. When the embedded electronic device 1 enters the function operation of the power saving mode, the computing system 10 only obtains part of the power supply from the battery 12 to reduce the power consumption of the battery 12 and achieve power saving effect, and the computing system 10 cooperates ...
