研華工控機產品故障簡要說明

. . 產(chan)品(pin)故(gu)障的簡單處理方法 

 1.主板(ban)硬件故(gu)障(zhang) 問:工控機(ji)最(zui)近突然不(bu)能正常啟動了。每次接通電源只能聽見CPU風扇在轉,但顯(xian)示器卻不(bu)亮(liang),機(ji)器也沒有(you)報警的提示。請問該如何(he)處理?

 答:如果(guo)通(tong)電(dian)后CPU風扇可以正(zheng)常運(yun)轉,那(nei)么可以初步證(zheng)明電(dian)源是(shi)正(zheng)常的(de)(de)(de),而顯示器(qi)點不亮且(qie)主(zhu)(zhu)板沒有報警提示那(nei)說明問題(ti)的(de)(de)(de)根源是(shi)出(chu)在主(zhu)(zhu)板上。打開(kai)機箱仔(zi)細檢查(cha)主(zhu)(zhu)板,如果(guo)發現你主(zhu)(zhu)板上的(de)(de)(de)電(dian)容上方(fang)有液體流(liu)出(chu)或(huo)者引腳斷開(kai)等情況,是(shi)電(dian)容爆漿,也(ye)是(shi)主(zhu)(zhu)板老化所造成的(de)(de)(de),仔(zi)細觀察,如果(guo)發現主(zhu)(zhu)板上的(de)(de)(de)芯片已(yi)經燒掉(diao),基本(ben)上就可以確定是(shi)主(zhu)(zhu)板故障了(le)。 

 2.極(ji)其隱蔽(bi)的存(cun)故(gu)障 問:最近(jin)不知(zhi)為什(shen)么當我(wo)第一次運行(xing)某個(ge)應(ying)用軟件沒事(shi),但關閉后(hou)再打開(kai)電(dian)腦(nao)就會重啟?

答:首(shou)先(xian)要(yao)確定在軟件方面沒有問題(ti),如果沒有,問題(ti)是(shi)出在存上(shang)面,很有可(ke)能是(shi)存的某(mou)一(yi)個(ge)顆(ke)(ke)粒(li)脫焊引發的存讀取(qu)錯誤。因為能進(jin)入(ru)系(xi)統(tong)且第(di)一(yi)次(ci)運(yun)行大(da)程(cheng)序(xu)可(ke)能沒有讀取(qu)到(dao)那顆(ke)(ke)壞掉的顆(ke)(ke)粒(li),當(dang)退出程(cheng)序(xu)后再(zai)次(ci)進(jin)入(ru)游戲就有可(ke)能要(yao)調用到(dao)它,并由(you)此引發存讀寫錯誤,重啟也是(shi)必然(ran)的了(le)。 

3.主機插上電源就自動(dong)啟(qi)動(dong) 問:碰到過好幾次都是直接電源線插上主機機器就開始啟(qi)動(dong),這時還沒(mei)有按電源鍵(jian)。有沒(mei)有解(jie)決的辦法啊? 

 答:這(zhe)個(ge)(ge)(ge)故障原因來(lai)自(zi)兩個(ge)(ge)(ge)方面,一(yi)(yi)是(shi)因為(wei)(wei)(wei)BIOS中的一(yi)(yi)些設置(zhi)(zhi)不(bu)正確(que)。在(zai)BIOS找到“INTEGRATED PHRIPHERALS SETUP”,有個(ge)(ge)(ge)“PWRON After PWR-Fail”的設置(zhi)(zhi)選項(xiang)管(guan)理這(zhe)個(ge)(ge)(ge)功(gong)能。其選項(xiang)分別(bie)為(wei)(wei)(wei)“On(開(kai)機(ji))”、“Off(關(guan)(guan)(guan)機(ji))”和“Former-Sts(恢復到到斷電(dian)(dian)(dian)前狀(zhuang)態(tai))”。您(nin)應(ying)該將它(ta)設置(zhi)(zhi)為(wei)(wei)(wei)“Off”。這(zhe)樣在(zai)打開(kai)電(dian)(dian)(dian)源開(kai)關(guan)(guan)(guan)或(huo)停電(dian)(dian)(dian)后突然(ran)來(lai)電(dian)(dian)(dian)等情況下,電(dian)(dian)(dian)腦就(jiu)不(bu)會自(zi)動(dong)(dong)啟動(dong)(dong)了。此(ci)外,您(nin)可以把網(wang)絡喚醒、鍵盤喚醒等自(zi)動(dong)(dong)開(kai)機(ji)功(gong)能設置(zhi)(zhi)為(wei)(wei)(wei)“Disable”。第二(er)個(ge)(ge)(ge)原因來(lai)自(zi)插座(zuo)和電(dian)(dian)(dian)源線(xian),ATX電(dian)(dian)(dian)源的啟動(dong)(dong)是(shi)靠檢測一(yi)(yi)個(ge)(ge)(ge)電(dian)(dian)(dian)容的電(dian)(dian)(dian)平(ping)信(xin)號(hao)來(lai)驅動(dong)(dong)的,在(zai)按下電(dian)(dian)(dian)源插座(zuo)開(kai)關(guan)(guan)(guan)或(huo)插上(shang)機(ji)箱電(dian)(dian)(dian)源插頭時,都會產生一(yi)(yi)個(ge)(ge)(ge)短暫的沖擊電(dian)(dian)(dian)流,如(ru)果(guo)插座(zuo)或(huo)電(dian)(dian)(dian)源線(xian)不(bu)過關(guan)(guan)(guan)很容易引起ATX電(dian)(dian)(dian)源的誤動(dong)(dong)作,使(shi)機(ji)器啟動(dong)(dong)。因此(ci)您(nin)可以試著先設置(zhi)(zhi)BIOS的有關(guan)(guan)(guan)選項(xiang),如(ru)果(guo)無效可以更換插座(zuo)和電(dian)(dian)(dian)源線(xian)。
