启动后，光标和键盘输入会周期性地滞后/卡顿 3 小时

当我启动电脑时，键盘输入和光标会每半秒延迟和抖动一次，持续整整 3 个小时。这意味着光标在被拖动或单击某物时会暂停几毫秒，然后继续，然后停顿，然后继续，如此反复，持续整整 3 个小时。键盘在这段时间内也无法接收输入。3 个小时过后，一切都恢复正常。

您在下面看到的不是视频延迟或计算机延迟。而是光标。

在此处输入图片描述

注意，动作并不像应该的那样流畅。光标在被拖动时会暂停。

这是我的系统信息。我使用的是 Linux Mint：

我已检查过top，没有发现任何可能导致这种情况的异常情况。

原来问题出在我电脑的电池上。我的电池很弱，无法充电。更换电池后，一切正常。
