對主(zhu)板的灰塵應定時清潔，不能用酒(jiu)精(jing)或(huo)水，應用干(gan)刷子、吸(xi)塵器或(huo)皮老虎把灰塵吸(xi)完或(huo)吹(chui)掉。保(bao)持(chi)主(zhu)板上內存扦槽的干(gan)凈，無(wu)斷腳、歪腳。主(zhu)板下插入無(wu)源底板中的金手指(zhi)要干(gan)凈，在底板上要插緊、插到位。

　　（2）、西門子計算機PC847開機啟動無反應維修技巧工控(kong)機箱中包括工控(kong)電(dian)(dian)源、無源底板、風扇。工控(kong)電(dian)(dian)源：它是為N小(xiao)時不間斷開(kai)機服務的(de)(de)，所以它的(de)(de)性能較好，主要(yao)需(xu)注意的(de)(de)是盡(jin)量(liang)減(jian)少灰(hui)塵(chen)的(de)(de)進入，防(fang)止灰(hui)塵(chen)影響風扇的(de)(de)運行。防(fang)止瞬時斷電(dian)(dian)，瞬時斷電(dian)(dian)又突然來電(dian)(dian)往往會(hui)(hui)產生一個瞬間高的(de)(de)電(dian)(dian)壓，很可能“燒(shao)”壞電(dian)(dian)腦，電(dian)(dian)壓的(de)(de)波動(dong)（過低或過高）也會(hui)(hui)對電(dian)(dian)腦造成損傷(shang)。因(yin)此，應盡(jin)量(liang)配備電(dian)(dian)源。另外(wai)，還應防(fang)靜(jing)電(dian)(dian)、防(fang)雷擊。

　　（3）無源底板(ban)：它是為各種板(ban)卡包括,)( 卡、顯卡、聲卡、網卡等）提供電(dian)(dian)源的，它的日常維護要(yao)注意(yi)三點(dian)：不能在底板(ban)帶電(dian)(dian)的情況(kuang)下撥插板(ban)卡
