1288323 九、發明說明： 【發明所屬之技術領域】 本發明係關於一種用於指示電腦狀態之電腦狀態指示 電路及具有該電腦狀態指示電路之電腦系統。 【先前技術】 電腦使用過程中，具有正常工作狀態和休眠狀態，如有 的電腦具有省電模式，當電腦一段時間無人使用後便自動進 入休眠狀態，或人們根據需要將電腦設置為工作狀態或休眠 狀態。 電腦主機板上之輸出管腳Power Led (工作輸出埠）和 Sleep Led (休眠輸出埠）分別對應電腦之工作狀態和休眠 狀態，如果電腦處於工作狀態，則Power Led輸出低電平， Sleep Led輸出高電平；如果電腦轉為休眠狀態，則改為 Power Led輸出高電平，而Sleep Led輸出低電平。 為顯示電腦之不同狀態，通常運用狀態指示燈，於不同 之狀態時，指示燈之顯示不同。有的係於電腦之主機板上設 置一個狀態指示燈，如中國大陸第03236782. 1號名為“電 腦狀態指示燈”之專利，即採用一個狀態指示燈，該指示燈 於電腦工作時持續發亮，於電腦休眠時閃爍。 然，現今電腦狀態指示燈之趨勢為設置兩個狀態指示 燈，為電腦功能改進時預留顯示多種狀態之空間。這兩個狀 態指示燈之正極都與電腦之電源連接，用於顯示工作狀態之 指示燈之負極與Power Led連接，因此該燈於電腦工作時持 續發亮，於電腦休眠時熄滅。用於顯示休眠狀態之指示燈之 負極與Sleep Led連接，於電腦休眠時熄滅，於電腦休眠時 持續發亮。也有於電腦之主機板上設置一個雙色之狀態指示 燈之，其原理與設置兩個狀態指示燈相同。 此等顯示電腦狀態之指示燈除設於主機板上以外，有的 電腦還將其同時設置於顯示器上，使用戶能夠直接從顯示器BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a computer status indicating circuit for indicating a state of a computer and a computer system having the computer status indicating circuit. [Prior Art] During the use of the computer, it has a normal working state and a sleep state. If some computers have a power saving mode, when the computer is not used for a period of time, the computer automatically enters a sleep state, or the user sets the computer to a working state as needed or Sleep state. The output pins Power Led (work output 埠) and Sleep Led (sleep output 埠) on the computer motherboard correspond to the working state and sleep state of the computer respectively. If the computer is in working state, Power Led outputs low level, Sleep Led output. High level; if the computer goes to sleep state, it will change to Power Led output high level, and Sleep Led output low level. In order to display the different states of the computer, the status indicator is usually used, and the indicators are displayed differently in different states. Some are set on the motherboard of the computer to set a status indicator, such as the Chinese patent No. 03236782. No. 1 "computer status indicator" patent, that is, a status indicator is used, which is continuously issued when the computer is working. On, flashes when the computer is sleeping. However, the trend of today's computer status indicators is to set two status indicators, which reserve space for displaying multiple states for computer function improvement. The positive poles of these two status indicators are connected to the power supply of the computer, and the negative pole of the indicator light for displaying the working status is connected with the Power Led, so the light is continuously illuminated when the computer is in operation, and is extinguished when the computer is in sleep. The negative side of the indicator light for displaying the sleep state is connected to the Sleep Led, and is turned off when the computer is in hibernation, and continues to illuminate when the computer is in hibernation. There is also a two-color status indicator on the motherboard of the computer, the principle is the same as setting the two status indicators. These indicators for displaying the status of the computer are not only installed on the motherboard, but some computers also set them on the display at the same time, so that the user can directly from the display.
