電腦主板計(jì)時(shí)專用晶振FC-12M時(shí)鐘晶振X1A000021000200

電腦里的實(shí)時(shí)時(shí)鐘與石英鐘是一樣的道理,要是不供電,實(shí)時(shí)鐘是不會(huì)走的。開機(jī)時(shí)由機(jī)箱電源供電,關(guān)機(jī)后由主板電池供電。由主板電池供電到機(jī)箱電源供電由一個(gè)專門電路切換。開機(jī)時(shí)實(shí)時(shí)鐘準(zhǔn)確,說明電源向32.768k晶振供電正常,32.768K晶振本身也沒有問題;關(guān)機(jī)斷電時(shí)鐘不走說明切換電路有故障,主板電池不能向32.768K晶振供電,因此32.768K晶振停振,因此時(shí)鐘不走了。所以這種故障應(yīng)重點(diǎn)檢查從主板電池到32.768之間的電路。重點(diǎn)檢查切換電路。往往由于一個(gè)小元件有問題就能發(fā)生這種故障。
