Thinkpad Yoga (15.10) 上的触控板和键盘行为不稳定

Question

我正在尝试解决一些一直困扰我的 Thinkpad Yoga 的问题，它运行的是 15.10。首先，触控板会一次停止工作几秒钟。仅这一点就让它几乎无法使用。但如果需要的话，我可以坚持使用触摸屏。但是，当触控板处于“停止工作”状态时，键盘开始表现得非常奇怪。有时一个键会“卡住”一秒钟左右，即使我只触摸过它一次。其他时候，按键到达应用程序的顺序与我输入的顺序相反。有时按下一个键和它出现之间会有延迟（通常与它反复出现相结合）。当我使用外接键盘/鼠标时不会出现这些问题。有时它可以正常工作很长时间，我很难找到任何模式。当鼠标问题发生时，系统日志显示以下内容：

有任何想法吗？

Answer 1

这似乎是连接问题 - 我拆开了机器，重新安装了键盘和触控板连接器，之后就再也没有出现任何问题。希望这种情况一直持续下去。

Answer 2

尝试在 BIOS 中禁用加速计，看看问题是否仍然存在。我发现当我将计算机倒置时会出现这些消息。
