计算机哔声代码列表及其含义

启动计算机时会发生很多事情。PC 做的第一件事是通过其POST 程序(POST programme )或开机(Power On Self Test)自检检查硬件是否工作正常。它在进入实际启动过程之前检查硬件兼容性和连接。如果您注意到，只要您按下电源按钮，它就会发出一声BEEP，然后启动。这种单一的哔哔声不是随机的。它表示在硬件层面一切正常。那么还有其他的蜂鸣模式吗？就在这里。查看 计算机哔声代码(Computer Beep codes)列表及其含义。

(HP Error Beep)带有通用核心 BIOS的(Common Core BIOS)HP 错误哔声代码

HP Beep代码与平时略有不同。有Major和Minor两种类型。Major指向错误类别，而Minor则(Minor)特定于类别内的问题，即长短闪烁，并伴有长短哔声

Number of long beeps/blinksError category
1Not used; Single beep/blinks are not used
2BIOS
3Hardware
4Thermal
5System board

闪烁/哔声代码的模式通过使用以下参数确定：

  • 1 秒的停顿发生在最后一次主要眨眼之后。
  • 2 秒的停顿发生在最后一次轻微眨眼之后。
  • 模式的前 5 次迭代会出现哔声(Beep)错误代码序列，然后停止。
  • 闪烁(Blink)错误代码序列一直持续到拔下计算机或按下电源按钮。
