Raspberry Pi 3B won't turn on after being powered on All In One

树莓派 3B 通电后无法开机

原因分析

指示灯只有红色的 LED 亮，绿色的 LED 不亮了 ❓

红色亮说明通电了，但是绿色不亮，即 PWR 指示灯工作正常 ✅, ACT 指示灯工作异常 ❌

LED Warning Flash Codes

https://www.raspberrypi.com/documentation/computers/configuration.html#led-warning-flash-codes

  1. 检查 LED

当 Raspberry Pi 引导时，一个或多个 LED 将激活。
一个 LED 为红色，表示电源（PWR）；
另一个 LED 为绿色，表示活动（ACT）。 （如果连接的话，还有三个LED指示灯指示以太网状态。）

那么这些 LED 指示灯指示什么？嗯，这是正常状态，即 PWR 和 ACT LED 均已激活。
SD卡活动期间，ACT将闪烁，而当电源降至 4.65V以下时，PWR 闪烁。
这样，如果红色PWR LED不亮，则表明没有电源。

如果只有红色 PWR LED 处于活动状态，并且没有闪烁，则表明 Pi 处于通电状态，但是有SD卡上没有可读的启动指令（如果有）。
在 Raspberry Pi 2上，ACT 和 PWR LED点亮表示相同。

从 SD卡启动时，ACT灯应不规则闪烁。
但是，它可以以更规范的方式闪烁以指示问题：

3闪烁：未找到 start.elf
4闪烁：start.elf 无法启动，因此可能已损坏; 或者，未正确插入卡或卡插槽不起作用。
8闪烁：无法识别 SDRAM。在这种情况下，您的 SDRAM 可能已损坏，或者无法读取 bootcode.bin 或 start.elf。

如果出现以上任何一种情况，请尝试使用新的 SD 卡, 重新安装 Raspberry Pi OS 操作系统。

解决方案

重装系统 ✅

  1. 使用一个新的 SD 卡, 验证树莓派本身没有损坏，只是 SD 或 系统损坏了；
  2. 重新安装树莓派系统
  3. 修改配置，SSH， WI-FI， static IP，关闭图形化界面，中文语言包...
