Computer system and operation method for changing operation state by capacitive button group

摘要

An operation method for a computer system includes: a capacitance button controller detecting whether a capacitance button group is touched; if a capacitance power button of the capacitance button group is touched, a system platform receiving a power button signal in a first logic state and changing an operation state of the system platform; if the capacitance power button is touched for longer than a predetermined time, shutting down the system platform; if the capacitance power button is touched for not longer than the predetermined time, the system platform receiving the power button signal in a second logic state and determining a subsequent operation status of the system platform and the capacitance button controller based on a system status signal; and if the capacitance button group is touched but the capacitance power button is not touched, the capacitance button controller entering into a power-saving state.

1. An operation method for a computer system, comprising:
detecting by a capacitive button controller whether a capacitive button group is touched; receiving a power button signal in a first logic state by a system platform and changing an operation state of the system platform if a capacitive power button of the capacitive button group is touched; shutting down the system platform if the capacitive power button is touched for longer than a predetermined time; receiving the power button signal in a second logic state by the system platform and determining a subsequent operation state of the system platform and the capacitive button controller according to a system status signal if the capacitive power button is touched for not longer than the predetermined time; and the capacitive button controller entering into a power saving state if the capacitive button group is touched but the capacitive power button is not touched; wherein the capacitive button controller and a micro-controller are awakened in response to a touch on the capacitive button group, the micro-controller determines whether the capacitive power button is touched, the capacitive button controller and the micro-controller enter the power saving state if the capacitive power button is not touched, and the micro-controller sends the power button signal in the first logic state to the system platform to change the operation state of the system platform if the capacitive power button is touched.
