    Mainboard: Mạch khởi động nguồn - The motherboard triggers the power-on circuit 
     

     
    Khi nút PWR được nhấn, tín hiệu PWR_BTN# sẽ được gửi đến chân số 106 của IT8712F-A, nhận được tín hiệu này, chân 103 của IT8712F-A sẽ gửi tín hiệu PWRBTN# về cho ICH (chip Nam), nhận được tín hiệu này, ICH sẽ đáp trả bằng tín hiệu SUSB# về chân 102 của IT8712F-A, nhận được tín hiệu này chân 107 của IT8712F-A sẽ xuất tín hiệu PS_ON# về chân xanh là của giắc cắm nguồn ATX (chân 14 của giắc nguồn ATX) kéo chân xanh lá này xuống thấp, dẫn theo nguồn ATX sẽ hoạt động, các nguồn chính +5V, +12V, +3.3V từ ATX sẽ đồng loạt cấp cho mainboard. Hoàn tất quá trình khởi động nguồn.
     
    Trước khi kích nguồn:
     
    - Chân 98 của IT8712F-A có 5V (các IT8718, IT8720, IT8728.. có thể chỉ có 3VSB)
    - Chân kích nguồn thông với chân 106 của IT8712F-A và có 3.3V ~ 5V.
    - Chân 107 của IT8712F-A thông với chân Xanh lá có 3v3 ~ 5V.
    - Chân 103 của IT8712F-A có 3.3V.
     
    Sau khi kích nguồn:
     
    - Chân 103, 106 của IT8712F-A (trong lúc kích nguồn) sẽ trở về 0v xong lên 3.3V ~5V như bình thường.
    - Kiểm tra chân 103 bằng cách vừa đo chân 103, vừa bấm nút kích nguồn. Nếu không đúng, hay thay thử IT8712F-A này.
    - Chân 107 của IT8712F-A sẽ về mức 0V.
    - Chân 102 của IT8712F-A sẽ có 3.3V. Mất nguồn này có thể lỗi chip ICH.
     
    When the PWR switch is triggered, generates the PWR_BTN # signal to pin 106 of the IT8712F-A I/O, after the I/O receives this signal, through the first 103 feet issued a 3.3V voltage jump PWRBTN# signal to the South Bridge. South bridge after receiving this signal, issue a 3.3V SUSB # signal to I/O at pin 102 (SUSB # similar to W83627 I/O inside the SLP_S3# signal), After the I/O receives the SUSB # signal, After the internal logic of the 107 feet after the issue of a sustained low-level PS_ON # signal to the ATX power supply green line (the ATX interface pin 14), - ATX power supply after receiving this signal to work, Friends of the motherboard work required by the group of voltage, Complete the entire power process. (Google Translate).
