打開電源而工控機無反應 1、查看電(dian)源插座是否有電(dian)并與工(gong)控機正常連(lian)接 2、檢查工控機(ji)(ji)電源是(shi)否能正(zheng)常(chang)工作（開機(ji)(ji)后電源風扇(shan)是(shi)否轉動(dong)），顯示器是(shi)否與主(zhu)機(ji)(ji)連接(jie)正(zheng)常(chang) 3、打開(kai)機(ji)箱蓋查看電(dian)源(yuan)是(shi)否與工控機(ji)底板或主板連(lian)接正常；底板與主板接插處(chu)是(shi)否松(song)動；開(kai)機(ji)時底板或主板是(shi)否上電(dian)；ATX電(dian)源(yuan)是(shi)否 4、拔掉內(nei)存條開機是否報警 5、更換CPU或主(zhu)板

加(jia)電(dian)時(shi)，工控機底(di)板上的電(dian)源(yuan)指(zhi)示燈只亮一下就滅，無法加(jia)電(dian) 首先(xian)看(kan)是否機箱內有螺絲等(deng)異物，導致短路。其次察看(kan)有關電(dian)源(yuan)線是否接反，導致對地短路。再(zai)次利(li)用替換(huan)法，更換(huan)電(dian)源(yuan)、主板、底(di)板

三、工控機加電后，電源工作正常，主板沒有任何反映 首先去掉外圍的插卡及所連的設備，看工控機能否啟動；如果不能，可去掉內存，看是否報警；然后檢查CPU的工作，是否正常；最后 板是否正常。 四、工控機開機后，主板有自檢聲，而顯示器無顯示1、檢查顯示器是否與主機連接正常 2、另外插一塊顯示卡查看是否能正常顯示  3、清除CMOS（可能設置有錯誤）或者更換BIOS  4、 更換CPU板西門子顯示屏開機電源指示燈不亮修理電話（主(zhu)板集成顯(xian)(xian)卡）或(huo)(huo)顯(xian)(xian)示器 五、工控(kong)機開(kai)機后報警，顯(xian)(xian)示器無顯(xian)(xian)示1、打開(kai)機箱蓋查看內存條是否(fou)安(an)裝或(huo)(huo)者松(song)動  2、拔掉(diao)內存條開(kai)機后報警聲是否(fou)相(xiang)同(tong) 3、清除(chu)COMS（可能(neng)設置有錯誤(wu)）或(huo)(huo)者更(geng)換(huan)BIOS  4、更(geng)換(huan)顯(xian)(xian)示卡或(huo)(huo)外插一塊(kuai)顯(xian)(xian)示卡（主(zhu)板集成顯(xian)(xian)卡）
