问题 (The Question)

SuperUser reader MiHa wants to know how to create a task in Task Scheduler for battery level changes on his laptop:

超级用户阅读器MiHa想知道如何在Task Scheduler中创建任务以在笔记本电脑上更改电池电量：

I need to create a task in Task Scheduler based on battery level changes. For example, say my laptop’s battery drops from 67 percent to 66 percent charge remaining. How can I run a task based on this event? Does Windows log this at all? I was unable to find information on this anywhere.

我需要根据电池电量变化在任务计划程序中创建任务。 例如，假设我的笔记本电脑的电池剩余电量从67％下降到66％。 如何基于此事件运行任务？ Windows是否完全记录了此信息？ 我无法在任何地方找到有关此信息。

I Need to Create a Task in Task Scheduler Based on Battery Level Changes

我需要根据电池电量变化在任务计划程序中创建任务

Windows does not log this kind of information/details as events. You can, however, use something like the batch file below and create a custom event.

Windows不会将此类信息/详细信息记录为事件。 但是，您可以使用下面的批处理文件之类的东西并创建一个自定义事件。

Battery.cmd

电池.cmd

This batch file monitors the current battery percentage charge and creates a user defined event if the charge drops below a user defined threshold value.

该批处理文件监视当前电池百分比电量，如果电量下降到用户定义的阈值以下，则创建用户定义的事件。

Notes:

笔记：

• The eventcreate command works on Windows XP up to and including Windows 10. It requires administrator privileges to work.
  eventcreate命令在Windows XP以及更高版本的Windows 10上均可使用。它需要管理员权限才能工作。
• Set _threshold as required.
  根据需要设置_threshold。
• If the battery falls below this value, an event with ID 999 will be generated in the APPLICATION event log with the description “Battery charge has dropped”.
  如果电池低于该值，则将在APPLICATION事件日志中生成ID为999的事件，其描述为“电池电量已下降”。
• Modify the eventcreate command as required for your situation.
  根据您的情况修改eventcreate命令。
• Modify the timeout delay as required for your situation.
  根据您的情况修改超时延迟。

Example Output

示例输出

My battery currently has a charge of 81 percent. I set the threshold to 82 percent. Here is what happens when I run Battery.cmd:

我的电池当前电量为81％。 我将阈值设置为82％。 当我运行Battery.cmd时，会发生以下情况：

And here is the new entry in the Event Log:

这是事件日志中的新条目：
