The plurality of lights 141, 142, 143, and 144 are displayed in a system state display mode to display the system state of the notebook computer 100. For example, the light source 141 is a power light number for displaying whether the notebook computer 100 is powered on. The light number 142 is a wireless network light number for indicating whether the wireless network device of the notebook computer 100 is turned on; the light number 143 is a battery charging light signal for indicating whether the notebook computer 100 is coupled to the transformer via the transformer.

The above-mentioned lights 141, 142, 143, and 144 are only for explaining one embodiment of the present invention. In other embodiments of the present invention, other lights may be included for displaying other system states of the notebook computer 100.
如第2圖所示，本發明筆記型電腦之內部電路包含一中央處理單元210，一晶片組220，一記憶體230，一內嵌控制單元(Embedded Controller)240，一電源供應單元250，及其它介面電路。內嵌控制單元240係用以執行多種控制功能，例如鍵盤控制功能、散熱管理功能、電池管理功能、開關管理功能、電源控制功能等。內嵌控制單元240係透過匯流排耦接於電池130之控制電路132以得知電池130之電量。本發明筆記型電腦之內部電路另包含一燈號切換模組260，及一偵測單元270。燈號切換模組260係用以切換複數個燈號141、142、143、144於系統狀態顯示模式及一電池電量顯示模式之間。當燈號141、142、143、144係處於電池電量顯示模式時，燈號141、142、143、144係用以顯示筆記型電腦100之電池130之電量。偵測單元270係耦接於筆記型電腦100之鍵盤120之一功能鍵122、 電源供應單元250及內嵌控制單元240。一般而言，當筆記型電腦100關機且未經由變壓器耦接至電源插座時(即ACPI定義之G3 Mode)，內嵌控制單元240係為關閉狀態，且電源供應單元250不供應電源給內嵌控制單元240，以減少電池130的耗電，此時若偵測單元270偵測到鍵盤120上之功能鍵122被觸發時，偵測單元270會開啟電源供應單元250，以使電源供應單元250供應電源至內嵌控制單元240，進而啟動內嵌控制單元240，另外，偵測單元270亦會傳送一控制訊號至內嵌控制單元240以通知內嵌控制單元240控制燈號切換模組260切換燈號至電池電量顯示模式。硬碟燈號144原本係由晶片組220獨立控制，當燈號切換模組260切換燈號141、142、143、144至電池電量顯示模式時，燈號切換模組260之硬碟燈號信號切換單元262會將硬碟燈號144之導通路徑耦接至內嵌控制單元240，以使內嵌控制單元240能於電池電量顯示模式時控制硬碟燈號144之明暗。燈號切換模組260之燈號供電切換單元264亦會於電池電量顯示模式時切換燈號141、142、143、144之供電來源，以使內嵌控制單元240能直接控制燈號141、142、143、144之明暗。 As shown in FIG. 2, the internal circuit of the notebook computer of the present invention comprises a central processing unit 210, a chipset 220, a memory 230, an embedded control unit 240, a power supply unit 250, and Other interface circuits. The embedded control unit 240 is configured to perform various control functions such as a keyboard control function, a heat dissipation management function, a battery management function, a switch management function, a power control function, and the like. The embedded control unit 240 is coupled to the control circuit 132 of the battery 130 through the bus bar to know the power of the battery 130. The internal circuit of the notebook computer of the present invention further includes a signal switching module 260 and a detecting unit 270. The signal switching module 260 is configured to switch between the plurality of lights 141, 142, 143, and 144 between the system state display mode and a battery power display mode. When the lights 141, 142, 143, 144 are in the battery power display mode, the lights 141, 142, 143, 144 are used to display the power of the battery 130 of the notebook computer 100. The detecting unit 270 is coupled to one of the function keys 122 of the keyboard 120 of the notebook computer 100, The power supply unit 250 and the embedded control unit 240. In general, when the notebook computer 100 is turned off and not coupled to a power outlet via a transformer (ie, GPI mode defined by ACPI), the embedded control unit 240 is in a closed state, and the power supply unit 250 does not supply power to the inline. The control unit 240 is configured to reduce the power consumption of the battery 130. When the detecting unit 270 detects that the function key 122 on the keyboard 120 is triggered, the detecting unit 270 turns on the power supply unit 250 to enable the power supply unit 250. The power supply is applied to the embedded control unit 240 to activate the embedded control unit 240. In addition, the detection unit 270 also transmits a control signal to the embedded control unit 240 to notify the embedded control unit 240 to control the light number switching module 260 to switch. Light to battery level display mode. The hard disk light number 144 is originally independently controlled by the chip set 220. When the light number switching module 260 switches the light number 141, 142, 143, 144 to the battery power display mode, the hard disk light signal of the light source switching module 260 The switching unit 262 couples the conduction path of the hard disk light number 144 to the embedded control unit 240 to enable the embedded control unit 240 to control the brightness of the hard disk light number 144 in the battery power display mode. The light source power switching unit 264 of the light source switching module 260 also switches the power source of the light signals 141, 142, 143, 144 in the battery power display mode, so that the embedded control unit 240 can directly control the light signals 141, 142. 143, 144 is dark and dark.
依據上述配置，當筆記型電腦100關機且未經由變壓器耦接至電源插座時(亦即筆記型電腦100只使用電池之電源，並處於ACPI定義之G3 Mode)，本發明可利用偵測單元270偵測鍵盤120之功能鍵122(例如Fn鍵)是否有被使用者按壓，以決定是否供電給內嵌控制器240，並進而顯示電池130之電量。如此筆記型電腦100可以在 不供應電源至內嵌控制器240的情況下，根據功能鍵122的按壓與否隨時進入電池電量顯示模式。由於偵測單元270可利用微弱之電源，例如低壓差(Low Dropout,LDO)電壓來偵測功能鍵122是否有被使用者按壓，相較於啟動內嵌控制器240以偵測功能鍵122是否有被使用者按壓而言，偵測單元270之耗電遠小於內嵌控制器240之耗電，因此偵測單元270之設計可避免當筆記型電腦100未開機時內嵌控制器240耗電之發生。 According to the above configuration, when the notebook computer 100 is turned off and is not coupled to the power socket via the transformer (that is, the notebook computer 100 uses only the power of the battery and is in the G3 mode defined by ACPI), the present invention can utilize the detecting unit 270. It is detected whether the function key 122 (for example, the Fn key) of the keyboard 120 is pressed by the user to determine whether to supply power to the embedded controller 240, and thereby display the power of the battery 130. Such a notebook computer 100 can be When the power is not supplied to the embedded controller 240, the battery power display mode is entered at any time according to whether the function key 122 is pressed or not. The detecting unit 270 can detect whether the function key 122 is pressed by the user by using a weak power source, such as a low dropout (LDO) voltage, compared to the activation of the embedded controller 240 to detect whether the function key 122 is detected. When the user presses, the power consumption of the detecting unit 270 is much smaller than that of the embedded controller 240. Therefore, the detecting unit 270 is designed to prevent the embedded controller 240 from being used when the notebook computer 100 is not turned on. It happened.
另外，偵測單元270產生之控制訊號除了可用以通知內嵌控制單元240控制燈號切換模組260切換燈號141、142、143、144至電池電量顯示模式外，偵測單元270產生之控制訊號亦可通知內嵌控制單元240控制筆記型電腦100執行其他預定操作，例如播放音樂等操作。如此筆記型電腦100可以在不開機的情況下根據功能鍵122的按壓與否執行其他預定操作。 In addition, the control signal generated by the detecting unit 270 can be controlled by the detecting unit 270, except that the embedded control unit 240 can be notified to control the light number switching module 260 to switch the light numbers 141, 142, 143, and 144 to the battery power display mode. The signal may also notify the embedded control unit 240 to control the notebook computer 100 to perform other predetermined operations, such as playing music. Thus, the notebook computer 100 can perform other predetermined operations according to whether the function keys 122 are pressed or not without being turned on.
請參考第3A圖至第3D圖，第3A圖至第3D圖為本發明電池電量顯示裝置根據電池之電量控制燈號之明暗數目的示意圖。內嵌控制單元240可根據筆記型電腦100之電池電量控制燈號141、142、143、144之明暗數目。舉例來說，如第3A圖所示，當電池電量高於75%時，內嵌控制單元240可根據電池電量點亮四個燈號141、142、143、144；如第3B圖所示，當電池電量介於50%至75%時，內嵌控制單元240可根據電池電量點亮三個燈號141、142、143；如第3C圖所示，當電池電量介於25%至50%時，內嵌控制單元240 可根據電池電量點亮兩個燈號141、142；如第3D圖所示，當電池電量低於25%時，內嵌控制單元240可根據電池電量點亮一個燈號141。另外，當筆記型電腦100經由變壓器耦接至電源插座以進行充電時，內嵌控制單元240可控制燈號閃爍以表示電池正在充電。舉例來說，當電池電量介於50%至75%時，內嵌控制單元240可根據電池電量點亮三個燈號141、142、143，並控制燈號144閃爍；當電池電量介於25%至50%時，內嵌控制單元240可根據電池電量點亮兩個燈號141、142，並控制燈號143閃爍；而當電池電量低於25%時，內嵌控制單元240可根據電池電量點亮一個燈號141，並控制燈號142閃爍。上述控制燈號之明暗的方法只是本發明其中之一實施例，在本發明其他實施例中，可以用其他不同方式控制燈號之明暗。 Please refer to FIG. 3A to FIG. 3D . FIG. 3A to FIG. 3D are schematic diagrams showing the number of light and dark of the battery level display device according to the battery power control amount according to the battery. The embedded control unit 240 can control the number of light and dark of the light numbers 141, 142, 143, 144 according to the battery power of the notebook computer 100. For example, as shown in FIG. 3A, when the battery power is higher than 75%, the embedded control unit 240 can illuminate the four lights 141, 142, 143, 144 according to the battery power; as shown in FIG. 3B, When the battery power is between 50% and 75%, the embedded control unit 240 can illuminate three lights 141, 142, 143 according to the battery power; as shown in FIG. 3C, when the battery power is between 25% and 50% At the time, the embedded control unit 240 The two lights 141, 142 can be illuminated according to the battery power; as shown in FIG. 3D, when the battery power is lower than 25%, the embedded control unit 240 can illuminate a light 141 according to the battery power. In addition, when the notebook computer 100 is coupled to a power outlet via a transformer for charging, the embedded control unit 240 may control the flashing of the light to indicate that the battery is being charged. For example, when the battery power is between 50% and 75%, the embedded control unit 240 can illuminate the three lights 141, 142, 143 according to the battery power, and control the light 144 to flash; when the battery power is 25 When the ratio is from 50% to 50%, the embedded control unit 240 can illuminate the two lights 141, 142 according to the battery power, and control the light 143 to blink; and when the battery power is lower than 25%, the embedded control unit 240 can be based on the battery The battery is illuminated by a light 141 and the control light 142 is flashing. The above method for controlling the brightness of the light is only one of the embodiments of the present invention. In other embodiments of the present invention, the brightness of the light can be controlled in other different ways.
相較於先前技術，本發明電池電量顯示裝置可以在筆記型電腦關機且只使用電池之電源時，利用偵測單元偵測鍵盤之功能鍵是否有被使用者按壓，以決定是否供電給內嵌控制器，並進而顯示電池電量。如此筆記型電腦可以在不持續供應電源至內嵌控制器的情況下，根據功能鍵的按壓與否隨時進入電池電量顯示模式，以減少電池之耗電。再者，本發明電池電量顯示裝置係利用筆記型電腦原有之燈號來顯示電池之電量，因此本發明電池電量顯示裝置不會增加電池模組的體積和複雜性。本發明電池電量顯示裝置可以方便且有效率地顯示電池之電量給使用者。 Compared with the prior art, the battery power display device of the present invention can detect whether the function key of the keyboard is pressed by the user when the notebook computer is powered off and only uses the power of the battery to determine whether to supply power to the embedded device. The controller, and in turn, displays the battery level. Such a notebook computer can enter the battery power display mode at any time according to whether the function key is pressed or not, without continuously supplying power to the embedded controller, so as to reduce the power consumption of the battery. Furthermore, the battery power display device of the present invention uses the original signal of the notebook computer to display the power of the battery. Therefore, the battery power display device of the present invention does not increase the volume and complexity of the battery module. The battery power display device of the present invention can display the power of the battery to the user conveniently and efficiently.
