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(yīng)先排除電源問題，然后再考慮其他部件。 二、先檢查外部設(shè)備，后檢查主機(jī) 由外部設(shè)備引起的故障通常更容易發(fā)現(xiàn)和排除，可以先根據(jù)系統(tǒng)報錯信息檢查外部設(shè)備的各種連線和自身的工作情況;排除外部設(shè)備的原因后，再考慮主機(jī)。 三、先檢查軟件，后檢查硬件 嵌入式主板出現(xiàn)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(fù)雜故障 硬件產(chǎn)品并不易損，所以當(dāng)遇到硬件故障時，應(yīng)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(jī)械部分更復(fù)雜的故障。
