Description

电源管理方法及计算机系统 Power management method and a computer system

技术领域 FIELD

[0001] 本发明涉及一种电源管理方法及计算机系统,尤指一种可提升计算机系统中电源管理灵活性的电源管理方法及计算机系统。 [0001] The present invention relates to a power management method and a computer system, particularly to a computer system can improve the flexibility of the power management method and a computer system power management.

背景技术 Background technique

[0002] 笔记本型计算机有着体积小、重量轻、携帯方便等特性,能够让使用者轻易地在办公室以外的地方进行工作,并使用计算机系统的各种功能,而不必再被笨重的桌上型计算机限制在桌面之前。 [0002] notebook computer with a small size, light weight, easy to carry Bands and other features to allow users to easily work in a place outside of the office, and use the various functions of a computer system, without having to be bulky desktop prior to the desktop computer restrictions. 为了方便使用者随身携帯,笔记本型计算机皆配备有用来储存电力的充电电池,以提供操作时所需的电力。 For convenience of the user, carry on Bands, notebook computers are equipped with electric power required when the rechargeable battery for storing electric power, to provide the operation. 由于充电电池所能储存的电量有限,当充电电池的电量耗尽时,使用者必需更换电量充足的电池或使用其他电カ来源,才能继续使用笔记本型计算机。 Since rechargeable batteries can store a limited amount of power, when the rechargeable battery is exhausted, the user must replace with a fully charged battery or other power source grades, in order to continue to use the notebook computer.

[0003] 因此,为了減少频繁更换电池所帯来的不便,除了笔记本型计算机原有的待机或休眠机制外,一般使用者在不需使用笔记本型计算机时,可将笔记本型计算机切换至关机状态。 [0003] Accordingly, in order to reduce the frequency of battery replacement Bands to inconvenience, a notebook computer in addition to the original standby or hibernate mechanism, generally without the use of the user when the notebook computer, the notebook computer may be switched to the off state. 所谓“关机状态”是指高级配置与电源接ロ(Advanced Configuration & PowerInterface)所定义的状态S5,表示所有设备皆关闭。 The so-called "off state" refers to the Advanced Configuration and Power ro contact state S5 (Advanced Configuration & PowerInterface) defined, meaning that all devices are turned off. 理论上,在状态S5下,笔记本型计算机的功耗为0,但实际上,笔记本型计算机的嵌入式控制器(Embedded Controller),如键盘控制器,操作于深度睡眠模式(De印Sleep Mode),仍会消耗15_20mW的电源,而此电源用来快速唤醒键盘控制器,或是支持网络或调制解调器启动(Wakeup on LAN/ffakeup onModem)等。 Theoretically, in the state S5, the notebook computer power is zero, but in fact, notebook computer embedded controller (Embedded Controller), such as a keyboard controller, operating in deep sleep mode (printing De Sleep Mode) , 15_20mW still consume power, and this power is used to quickly wake keyboard controller, a modem or network support or boot (wakeup on LAN / ffakeup onModem) and the like. 換言之,即便使用者将笔记本型计算机切换至关机状态,笔记本型计算机仍会消耗电源。 In other words, even if the notebook computer user to switch to a shutdown state, a notebook computer still consume power. 在此情形下,若笔记本型计算机使用电池电源,势必会降低电池电量,以致减少可携使用时间。 In this case, when the notebook computer battery power, battery power is bound to be reduced, so as to reduce time portability.

[0004] 若要使键盘控制器完全不耗电,则需将键盘控制器操作于完全停机(Shutdown)模式。 [0004] To make the keyboard controller completely power, the controller operates the keyboard need to completely shut down (the Shutdown) mode. 然而,当键盘控制器处于完全停机模式,当使用者按下电源键开机时,会比键盘控制器处于深度睡眠模式的时候,需要更长的启动时间。 However, when the keyboard controller is in full shutdown mode, when the user presses the power button to boot, will be in deep sleep mode than the keyboard controller require a longer startup time. 主要原因在于,当键盘控制器从完全停机模式重新启动时,键盘控制器需要花费时间在执行初始化的程序,包含了检查各个通用输入输出(General Purpose Input/Output)接ロ的状态,并执行相对应的程序。 The main reason is that, when restarting from the keyboard controller completely shut down mode, a keyboard controller takes time in the program initialization is performed, each comprising a general purpose input output checking (General Purpose Input / Output) ro contact state, and performs phase corresponding program. 一般而言,键盘控制器初始化所需的时间,将近0.5秒。 Generally the time, required to initialize the keyboard controller, approximately 0.5 seconds. 因此,若每次关机,键盘控制器都进入完全停机模式,由于重新启动所需要的时间较长(> 0.5秒),会对使用者造成影响。 Thus, if each shutdown, a keyboard controller are entered completely shut down mode, the restart time longer required (> 0.5 seconds), it will affect the user.

[0005] 由上述可知,若笔记本型计算机关机时,键盘控制器操作于深度睡眠模式,则可降低启动时间,但会额外消耗电力。 [0005] From the above, if the notebook computer is shut down, a keyboard controller operating in deep sleep mode, the startup time can be reduced, but extra power consumption. 反之,若笔记本型计算机关机时,键盘控制器操作于完全停机模式,虽可使功耗降至0,但重新启动所需要的时间较长。 Conversely, if the notebook computer is turned off, the keyboard controller is fully operational in shutdown mode, although power consumption can be reduced to zero, but is restarted longer needed. 由此可知,公知技术缺乏灵活性,无法因应不同状态而调整关机时的操作方式,实有改进的必要。 It can be seen, known techniques lack flexibility and can not be adjusted in response to the different states of operation at the time of the shutdown, there is a need for improvement.

具体实施方式 Detailed ways

[0015] 为了提升计算机系统中电源管理的灵活性,本发明增加一机制,由使用者根据所需,自行设定嵌入式控制器(如键盘控制器)关机时的模式。 [0015] In order to enhance the flexibility of power management in a computer system, a mechanism of the present invention increases, depending on the desired by a user, the setting mode when the embedded controller (e.g. keyboard controller) itself off.

[0016] 详细来说,请參考图1,图1为本发明实施例的ー电源管理流程10的示意图。 [0016] In detail, referring to FIG 1, FIG. 1 of the present ー power management process schematic of an embodiment 10 of the present invention. 电源管理流程10可提升ー计算机系统中电源管理的灵活性,其包含以下步骤: Power management process 10 can improve the flexibility ー power management in a computer system, comprising the steps of:

[0017] 步骤100:开始。 [0017] Step 100: Start.

[0018] 步骤102:产生ー设定指令CMD_SET,设定指令CMD_SET用来将计算机系统的ー嵌入式控制器的一旗标F (Flag)设定为一第一值Vl或一第二值V2。 [0018] Step 102: setting command generating ー CMD_SET, setting command CMD_SET ー embedded controller for the computer system of a flag F (Flag) is set to a first value or a second value V2 Vl . 若旗标F等于第一值VI,执行步骤104 ;反之,若旗标F等于第二值V2,执行步骤106。 If the flag F is equal to a first value Vl, step 104 is executed; otherwise, if the flag F is equal to the second value V2, step 106 is performed.

[0019] 步骤104:在计算机系统关机时,将嵌入式控制器切換至一深度睡眠模式。 [0019] Step 104: when the computer system is turned off, the embedded controller switches to a deep sleep mode.

[0020] 步骤106:在计算机系统关机时,将嵌入式控制器切換至一完全停机模式。 [0020] Step 106: when the computer system is turned off, the embedded controller switches to a full stop mode.

[0021] 因此,通过电源管理流程10,使用者可以藉由设定指令CMD_SET,将嵌入式控制器的旗标F设定为第一值Vl或第二值V2,使嵌入式控制器在计算机系统关机时切换至深度睡眠模式或完全停机模式。 [0021] Accordingly, 10, the user can set by instruction CMD_SET, the flag F is set by the embedded controller power management process is a first value or a second value Vl V2, so that the embedded controller in the computer switching off the system to completely shut down mode or deep sleep mode. 亦即,当设定指令CMD_SET将旗标F设定为第一值Vl吋,嵌入式控制器在计算机系统关机时切换至深度睡眠模式,则关机后,嵌入式控制器会消耗特定电量,用来快速唤醒键盘控制器,或是支持网络或调制解调器启动等功能,使嵌入式控制器重新启动时不需执行初始化程序。 That is, when the setting command CMD_SET flag F is set to a first value Vl inches, embedded controller is switched off when the computer system to the deep sleep mode, after the shutdown, the embedded controller consumes a certain amount, with to quickly wake keyboard controller, or support a network or modem functions such as start, the embedded controller need not perform the initialization program restart. 相反地,当设定指令CMD_SET将旗标F设定为第二值V2吋,嵌入式控制器在计算机系统关机时切换至完全停机模式,则关机后,嵌入式控制器不会消耗电量,因此重新启动时,嵌入式控制器需执行初始化程序。 Conversely, when the flag set instruction CMD_SET F is set to a second value V2 inch, the embedded controller mode switch to completely shut down when the computer system is shut down, after the shutdown, the embedded controller does not draw power, thus when you restart, the embedded controller needs to perform the initialization procedure.

[0022] 简单来说,计算机系统的使用者可以根据所需,自行调整关机后嵌入式控制器的耗电量。 [0022] Briefly, in accordance with the user computer system may be required, the embedded controller adjusts itself off after the power consumption. 例如,若预期将长时间不使用计算机系统,则使用者可将藉由设定指令CMD_SET,将嵌入式控制器的旗标F设定为第二值V2,使嵌入式控制器在关机时切換至完全停机模式,以降低系统耗电量。 For example, if the expected not using the computer system, the user may be set by the instruction CMD_SET, the flag F is set to the embedded controller of a second value V2, at an embedded controller switches off to completely shut down mode to reduce system power consumption. 若使用者只是短时间内不使用计算机系统,或是希望计算机系统的启动速度快,则使用者可藉由设定指令CMD_SET,将嵌入式控制器的旗标F设定为第一值VI,使嵌入式控制器在关机时切換至深度睡眠模式;如此ー来,重新开机吋,嵌入式控制器不需执行初始化程序,以减少启动所需的时间。 If the user is not using the computer system only a short time, or desired fast start of the computer system, the user may be set by instructions CMD_SET, the flag F is set to the embedded controller of a first value Vl, so that the embedded controller to switch to deep sleep mode when turned off; thus ー, the reboot inch, without the embedded controller performs an initialization process to reduce the time required to start.

[0023] 由上述可知,藉由设定指令CMD_SET,使用者可自行调整电源管理,以降低关机后的电源消耗,抑或提升重开机时的效率。 [0023] From the foregoing, by setting command CMD_SET, the user can adjust the power management to reduce power consumption after shutdown, or to enhance the efficiency of the reboot. 需注意的是,电源管理流程10仅用以说明本发明的精神,凡依此所作的变化或修饰皆属本发明的范畴。 Note that, power management process 10 are intended to illustrate the spirit of the present invention, where the variations or modifications so made all belong to the scope of the invention. 举例来说,步骤102中设定指令CMD_SET的产生方式、格式或内容等不限于任何特定规则,例如可通过基本输入输出系统(BasicInput/Output System)或应用程序等产生。 For example, in step 102 the set of instructions is generated CMD_SET embodiment, formats or contents limited to any particular rule, for example, may be generated by a basic input output system (BasicInput / Output System) or application programs and the like. 若设定指令CMD_SET由基本输入输出系统所产生,可由使用者自行设定;若设定指令CMD_SET由应用程序所产生,则可达成一次性的控制,亦即每次重开机后,先前的设定会被清除。 If the instruction CMD_SET generated by the basic input output system, the user may set their own set; if the setting command CMD_SET generated by the application can be controlled to achieve a one-time, i.e. each reboot, previously provided set will be cleared. 同理,旗标F的格式或内容,及第ー值V1、第ニ值V2所对应的意义等,皆应根据不同需求而适当变化,而此等变化应为本领域普通技术人员所熟习的技艺。 Similarly, the flag F of the format or content, the second ー value V1, corresponding to the value of ni meaning as V2, etc., are to be appropriately changed depending on the needs, and such variations should be known to those of ordinary skill in the art are familiar with skill. 再者,前述说明中嵌入式控制器不限于键盘控制器,亦可以是计算机系统中其他组件或模块的控制器。 Furthermore, the foregoing description is not limited to the embedded controller keyboard controller, a computer system may also control other components or modules.

[0024]另外,本发明所应用的计算机系统较佳地为笔记本型计算机,但不以此为限,亦可以是桌上型计算机、平板计算机等。 [0024] Further, the computer system of the present invention is preferably applied to a notebook computer, but not limited to, also may be a desktop computer, a tablet computer. 以笔记本型计算机为例,通过本发明的电源管理流程10,使用者可自行决定要降低关机后的电源消耗,以延长便携使用时间,或是牺牲一部分电源,而提升重开机时的效率。 In a notebook computer as an example, the power management process 10 of the present invention, the user can decide to reduce power consumption after shutdown, to extend the time of portable use, or to sacrifice some power, and enhance the efficiency of re-boot. 因此,本发明提供了弾性化的电源管理机制,使得使用者可根据所需决定关机后的电源消耗或重开机时的效率。 Accordingly, the present invention provides a Tan of the mechanism of power management, so that the user can consume or re-boot according to the efficiency of the power required for the shutdown decision.

[0025] 综上所述,通过本发明,使用者可自行设定计算机系统的嵌入式控制器关机后的操作模式,以选择降低关机后的电源消耗,抑或提升重开机时的效率。 [0025] In summary, the present invention, the user can set the operation mode of the embedded controller of the computer system shut down to reduce power consumption selection after shutdown, or to enhance the efficiency of the reboot. 因此,本发明可有效提升计算机系统中电源管理的灵活性。 Accordingly, the present invention can effectively enhance the flexibility of the computer system power management.

[0026] 以上所述仅为本发明的较佳实施例,凡根据本发明权利要求书的范围所作的均等变化与修饰,皆应属本发明的涵盖范围。 [0026] The foregoing is only preferred embodiments of the present invention, all modifications and alterations of the present invention as claimed in the scope of the claims made, also belong to the scope of the present invention.
