当我将充电器连接到我的惠普笔记本电脑时，它的速度会急剧下降。笔记本电脑上没有负载，但我认为负载无关紧要，因为当移除充电器时，它工作正常。
它是配备 NVMe、16GB RAM（仅使用 5GB）的 HP-15-dy1xxx，安装了 Ubuntu 22.04，温度得到控制。
我不认为这是一个软件（驱动程序）问题，因为如果连接了充电器，则需要很长时间才能完成启动过程，并且在 BIOS 设置中它也运行得非常慢。
我运行了一个脚本来显示连接充电器时的性能差异，结果如下：
它运行无限的 for 循环并测量运行 100,000 次迭代所需的时间。
当我启动脚本时，充电器最初是连接的。

断开充电器后，大约需要 30-45 秒才能恢复正常性能。但重新连接时会立即节流。我尝试了不同的充电器，但结果相同。
有任何提示或帮助吗？
答案1
它在 BIOS 设置中的运行速度也非常慢。
这意味着该问题不是软件问题。
连接充电器可能会断开电池 - 硬件问题。机器需要电池和充电器才能以适当的速度运行。
电池电路（或电池本身）也可能存在硬件问题。
您需要将机器送到当地的维修店进行维修。
答案2
这是硬件问题。更换笔记本电脑的充电端口后，它现在工作正常。
答案3
我的戴尔笔记本电脑也遇到了几乎完全相同的问题。但有些不同 - 如果在启动时插入电源适配器，我会收到 BIOS 警告，提示电源适配器上的电压不正确。原因也非常相似。非品牌适配器上的物理连接器不够长，无法在内部进行适当的连接。我更换了电源适配器，之后它工作正常。
