嵌入式主板的硬件故障如何排除 一、先檢查電源，后件 電源的作用很重要，功率不足、輸出電壓電流異常等都會引起各種故障。因此，應先排除電源問題，然后再考慮其他部件。 二、先檢查外部設備，后檢查主機 由外部設備引起的故障通常更容易發現和排除，可以先根據系統報錯信息檢查外部設備的各種連線和自身的工作情況;排除外部設備的原因后，再考慮主機。 三、先檢查軟件，后檢查硬件 嵌入式主板出現故障后，先要排除軟件原因，再考慮硬件原因。 四、先考慮簡單故障，后考慮復雜故障 硬件產品并不易損，所以當遇到硬件故障時，應該從簡單的原因開始檢查，例如判斷各種線纜的連接是否正常，各種插卡是否接觸不良等。如果檢查后故障依舊，此時可考慮電路或元件機械部分更復雜的故障。
