Embodiment Construction

[0014] figure 1 It is a schematic diagram of the operating system of the present invention. The present invention does not limit the type of operating system 100. In a possible embodiment, the operating system 100 may be a personal computer or a portable electronic device, such as a notebook computer or a mobile phone. In this embodiment, the operating system 100 includes a chipset 113 and a detection unit 115.

[0015] The chipset 113 includes a first circuit group (not shown) for receiving multiple operating voltages. When an external power source 121 is abnormal, the detection unit 115 outputs a control signal to control the first circuit group to stop accessing a storage device (not shown). The switching of the control signal is earlier than the change of a first operating voltage among the operating voltages received by the first circuit group due to the abnormality of the external power supply 121.

[0016] In a possible embodiment, the chipset 113 also has a second circui...

Abstract

The invention discloses an operation system and a control method thereof. The operation system includes a chip group and a detection module. The chip group includes a first circuit group used for receiving a plurality of operation voltages. When the first external power source is abnormal, the detection module outputs a control signal to control the first circuit group to stop accessing the storage device. The switch of the control signal is earlier than the changes of the first operation voltage in the operation voltages caused by the abnormal of the external power source.

Description

Technical field [0001] The present invention relates to an operating system, in particular to an operating system that can stop a chipset from operating when the external power supply is abnormal. Background technique [0002] With the advancement of technology, the usage rate of electronic products is also increasing, such as desktop computers and portable products. However, no matter what kind of electronic product, it needs to be driven by an external power source. The external power supply will be converted into many operating voltages for use by components in electronic products. However, when the external power supply is unstable, it will cause the components in the electronic product to malfunction. Summary of the invention [0003] The invention provides an operating system, which includes a chipset and a detection unit. The chipset includes a first circuit group for receiving multiple operating voltages. When an external power source is abnormal, the detection unit ou...
