Dell Inspiron 筆記型電腦具有內建診斷指示器,例如嗶聲代碼或 LED 代碼。它們有助於診斷和解決筆記型電腦在啟動期間可能遇到的問題。指出筆記型電腦在開機自我測試 (POST) 期間的哪一點發生問題。這些可以是:
- 發出嗶聲
- 顯示不同狀態和顏色的電源按鈕
- 特定診斷 LED
- 兩者的結合
本文是每個 Inspiron 筆記型電腦上會出現的代碼以及這些代碼代表意義的參考指南。診斷指示器可能會因不同機型而有所不同,請參閱 Dell 筆記型電腦的說明文件,以取得特定裝置的資訊。這些指示器主要是協助您找出解決啟動問題的故障診斷步驟的起點。
目錄:
- Inspiron 筆記型電腦系列的診斷 LED (2020 年至 2025 年)
- Inspiron 筆記型電腦系列的診斷 LED (2016 年至 2020 年)
- Inspiron 筆記型電腦系列的診斷 LED (2006 年至 2016 年)
- Inspiron 筆記型電腦系列的診斷 LED (2006 年之前)
- Inspiron 筆記型電腦嗶聲代碼
- 縮寫詞彙表
注意:下表內的診斷 LED 僅作為 POST 程序進度的指示燈。這些 LED 無法指出造成 POST 故障的問題。
注意:筆記型電腦無法開機至與 POST 問題無關的作業系統的可能原因為何?筆記型電腦可完成 POST,且不會停止在特定錯誤代碼處,然後顯示黑色畫面。
Inspiron 筆記型電腦的診斷 LED (2020 年至 2025 年)
電源或電池 LED 狀態現在會增加閃爍次數和色彩變換模式,以指出發生問題的所在位置。

注意:若要查看內容,請按一下您要在下方開啟的章節標題。
注意:診斷錯誤代碼一律會取代任何其他的 LED。例如,當診斷錯誤代碼顯示時,便不會顯示電力偏低或電池故障情況的電池代碼。

注意:閃爍模式包含兩組數字,分別代表第一組(琥珀色閃爍)和第二組(白色閃爍)。
例如:未偵測到記憶體 (2, 3)。電池 LED 會以琥珀色閃爍兩次,接著暫停,然後以白色閃爍三次,然後暫停並重複。這種模式會持續直到筆記型電腦關機為止。
- 第一組:電池 LED 會以琥珀色閃爍最多九次,然後暫停 1.5 秒,然後再執行第二組。
- 第二組:電池 LED 會以白色閃爍最多九次,然後暫停 3 秒,然後再次執行第一組。

Inspiron 筆記型電腦系列的診斷 LED (2006 年之前)
這些筆記型電腦使用鍵盤按鈕 LED。除了 Inspiron 1501 外,這段時間的所有其他 Inspiron 機型均使用嗶聲代碼做為筆記型電腦上的診斷指示。

注意:若要查看內容,請按一下您要在下方開啟的章節標題。
這些機型的機箱正面有一個鍵盤狀態 LED 區塊,會穩定亮起綠色、閃爍綠色或熄滅。

如果筆記型電腦已連接至電力插座,電源或電池指示燈會如下運作:
- 穩定亮起綠色 – 電池正在充電。
- 閃爍綠色 – 電池已幾乎充飽。
如果筆記型電腦使用電池運作,則電池指示燈的運作方式如下:
- 熄滅 – 電池已充飽電 (或筆記型電腦已關閉)。
- 閃爍琥珀色 – 電池電量低。
- 琥珀色穩定 – 電池電量極低。
Inspiron 筆記型電腦嗶聲代碼
除了各種類型的診斷 LED 之外,這些筆記型電腦的機型還有多種嗶聲代碼。
這些代碼可在不同製造商中識別,且在一段時間內仍維持不變。
這些代碼的金鑰會顯示在下表中。
