西門子IPC677啟動無反應黑屏十年修復診斷：通電后CPU風扇和換氣風扇都正常，測量電壓也正常，但屏幕無任何反應，鏈接外接VGA也無顯示，由此證明主板有故障了，利用測試卡檢測，PCI時鐘有，復位也有，但不跑BIOS代碼。
維修流程(cheng)：當PCI時(shi)鐘(zhong)(zhong)和復(fu)(fu)位都有(you)的情況下(xia)，就只有(you)北橋(qiao)(qiao)(qiao)和CPU的復(fu)(fu)位和時(shi)鐘(zhong)(zhong)這幾個(ge)地方(fang)出(chu)問題才會導致主(zhu)(zhu)板(ban)不(bu)(bu)工作(zuo)，更換(huan)CPU后(hou)故障依舊，那(nei)剩下(xia)了北橋(qiao)(qiao)(qiao)和北橋(qiao)(qiao)(qiao)的時(shi)鐘(zhong)(zhong)還有(you)復(fu)(fu)位、CPU的時(shi)鐘(zhong)(zhong)和復(fu)(fu)位這5個(ge)部分。繼續排除后(hou)，CPU時(shi)鐘(zhong)(zhong)正(zheng)(zheng)常(chang)(chang)，但(dan)沒復(fu)(fu)位信(xin)(xin)(xin)號，復(fu)(fu)位信(xin)(xin)(xin)號來(lai)(lai)自北橋(qiao)(qiao)(qiao)，另外CPU供電(dian)(dian)(dian)也不(bu)(bu)對，只有(you)1.55V，正(zheng)(zheng)常(chang)(chang)時(shi)1.75v左右，CPU供電(dian)(dian)(dian)決定(ding)于是(shi)否復(fu)(fu)位，沒復(fu)(fu)位也不(bu)(bu)能得到正(zheng)(zheng)常(chang)(chang)的電(dian)(dian)(dian)壓(ya)。根據(ju)(ju)以上(shang)(shang)的思路，北橋(qiao)(qiao)(qiao)損壞可能性很大，很多現象(xiang)都反應到北橋(qiao)(qiao)(qiao)沒有(you)工作(zuo)，北橋(qiao)(qiao)(qiao)芯片(pian)組為VT8606即PN133T,更換(huan)北橋(qiao)(qiao)(qiao)芯片(pian)后(hou)，CPU復(fu)(fu)位電(dian)(dian)(dian)壓(ya)正(zheng)(zheng)常(chang)(chang)，時(shi)鐘(zhong)(zhong)也正(zheng)(zheng)常(chang)(chang)，但(dan)電(dian)(dian)(dian)壓(ya)還是(shi)偏低，CPU工作(zuo)電(dian)(dian)(dian)壓(ya)根據(ju)(ju)核(he)心來(lai)(lai)確定(ding)的，信(xin)(xin)(xin)號給電(dian)(dian)(dian)源管理(li)芯片(pian)后(hou)輸(shu)出(chu)額(e)定(ding)的電(dian)(dian)(dian)壓(ya)，使其正(zheng)(zheng)常(chang)(chang)運(yun)行，檢測(ce)后(hou)管理(li)芯片(pian)有(you)問題，更換(huan)后(hou)空載1.34v屬于正(zheng)(zheng)常(chang)(chang)電(dian)(dian)(dian)壓(ya)，裝上(shang)(shang)CPU后(hou)升至1.75v，主(zhu)(zhu)板(ban)開(kai)始跑BIOS代碼，電(dian)(dian)(dian)腦(nao)正(zheng)(zheng)常(chang)(chang)運(yun)行，維修完畢。
