我需要根据电池电量变化在 TS 中创建一个任务。假设我的电池电量从67%下降到66%。如何基于此事件运行任务。Windows 会记录这些吗?我在任何地方都找不到这些信息。

Windows 不会将此类详细信息记录为事件。但是,您可以使用类似于下面的批处理文件的内容并创建自定义事件。
该批处理文件监控当前电池电量百分比,并在电量低于用户定义的阈值时创建用户定义的事件。
@echo off
setlocal EnableDelayedExpansion
rem set threshold value
set _threshold=82
:start
rem get the battery charge
rem use findstr to strip blank lines from wmic output
for /f "usebackq skip=1 tokens=1" %%i in (`wmic Path Win32_Battery Get EstimatedChargeRemaining ^| findstr /r /v "^$"`) do (
set _charge=%%i
echo !_charge!
if !_charge! lss !_threshold! (
echo threshold reached
rem create a custom event in the application event log
rem requires administrator privileges
eventcreate /l APPLICATION /t WARNING /ID 999 /D "Battery charge has dropped"
goto :done
) else (
rem wait for 10 minutes then try again
timeout /t 600 /nobreak
goto :start
)
)
:done
endlocal

笔记:
Eventcreate
命令适用于 Windows XP 和包括 Windows 10,它需要管理员权限才能工作_threshold
根据需要设置999
将在 APPLICATION 事件日志中生成一个带有 ID的事件,并说明Battery charge has dropped
eventcreate
根据您的情况需要修改命令。timeout
根据您的情况修改延迟。示例输出:
我的电池目前有 81% 的电量。我将阈值设置为82
。这是我运行时发生的情况Battery.cmd
:
> battery
81
