Dell Inspiron 笔记本电脑具有集成诊断指示灯,例如哔声码或 LED 代码。它们有助于诊断和解决您的笔记本电脑在启动过程中可能遇到的问题。指示笔记本电脑在开机自检 (POST) 期间的哪个阶段出现问题。这些可以是:
- 蜂鸣音
- 显示不同状态和颜色的电源按钮
- 特定诊断 LED 指示灯
- 全部的组合
以下文章是有关 Inspiron 笔记本电脑上可用代码和这些代码含义的参考指南。诊断指示灯可能因不同型号而异,请参阅您的戴尔笔记本电脑的说明文件,了解特定于设备的信息。这些指示灯只是寻找解决启动问题的故障处理步骤的起点。
目录:
- Inspiron 灵越笔记本电脑系列(2020 至 2025)的诊断 LED 指示灯
- Inspiron 灵越笔记本电脑系列的诊断 LED 指示灯(2016 年至 2020 年)
- Inspiron 灵越笔记本电脑系列的诊断 LED 指示灯(2006 年至 2016 年)
- Inspiron 灵越笔记本电脑系列的诊断 LED 指示灯(2006 年之前)
- Inspiron 灵越笔记本电脑可听见的哔声码
- 首字母缩写词术语表
提醒:下表中的诊断 LED 指示灯用作开机自检过程的进度指示。这些 LED 指示灯不指示导致 POST 故障的问题。
提醒:笔记本电脑无法引导至与开机自检问题无关的作系统的可能原因是什么?笔记本电脑完成开机自检而不停止特定错误代码,然后显示黑屏。

如果笔记本电脑已连接至电源插座,则电池指示灯将呈现以下几种状态:
- 呈绿色稳定亮起 — 电池正在充电。
- 呈绿色闪烁 — 电池已基本充满电。
如果笔记本电脑使用电池运行,则电池指示灯将呈现以下几种状态:
- 熄灭 — 电池已充满电(或笔记本电脑已关闭)。
- 呈琥珀色闪烁 — 电池电量不足。
- 呈琥珀色稳定亮起 — 电池电量严重不足。
