我需要根据电池电量变化在TS中创建任务。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是否完全记录了此日志？我在任何地方都找不到此信息。
Answers:
Windows不会将此类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内容并创建自定义事件。
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。
@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命令在Windows XP及更高版本（包括Windows 10）上均可运行，需要管理员权限才能运行_threshold根据需要设置999则将在APPLICATION事件日志中生成一个ID为ID 的事件，其描述为Battery charge has droppedeventcreate根据您的情况修改命令。timeout根据您的情况修改延迟时间。输出示例：
我的电池当前电量为81％。我将阈值设置为82。这是我跑步时发生的情况Battery.cmd：
> battery
81
threshold reached
SUCCESS: An event of type 'WARNING' was created in the 'APPLICATION' log with 'EventCreate' as the source.
这是事件日志中的新条目：
EVENTCREATE [/S system [/U username [/P [password]]]] /ID eventid
[/L logname] [/SO srcname] /T type /D description
Description:
This command line tool enables an administrator to create
a custom event ID and message in a specified event log.
Parameter List:
/S system Specifies the remote system to connect to.
/U [domain\]user Specifies the user context under which
the command should execute.
/P [password] Specifies the password for the given
user context. Prompts for input if omitted.
/L logname Specifies the event log to create
an event in.
/T type Specifies the type of event to create.
Valid types: SUCCESS, ERROR, WARNING, INFORMATION.
/SO source Specifies the source to use for the
event (if not specified, source will default
to 'eventcreate'). A valid source can be any
string and should represent the application
or component that is generating the event.
/ID id Specifies the event ID for the event. A
valid custom message ID is in the range
of 1 - 1000.
/D description Specifies the description text for the new event.
/? Displays this help message.
Examples:
EVENTCREATE /T ERROR /ID 1000
/L APPLICATION /D "My custom error event for the application log"
EVENTCREATE /T ERROR /ID 999 /L APPLICATION
/SO WinWord /D "Winword event 999 happened due to low diskspace"
EVENTCREATE /S system /T ERROR /ID 100
/L APPLICATION /D "Custom job failed to install"
EVENTCREATE /S system /U user /P password /ID 1 /T ERROR
/L APPLICATION /D "User access failed due to invalid user credentials"
有一个事件ID为13 的Microsoft-Windows-BatteryETW提供程序BatteryPercentRemaining。您可以编写一个使用TraceEvent为该提供程序创建实时侦听器的项目Microsoft-Windows-Battery。该事件具有RemainingPercentage显示状态和PercentageChange查看更改的条目：
当您看到此事件并看到的-1更改时PercentageChange，请运行所需的程序。
好的，DavidPostill提供的脚本不起作用。这是一个不错的小脚本，但是代码不固定或过时。
@echo off
setlocal EnableDelayedExpansion
rem set threshold value
set _threshold=30
: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 below the threshold."
goto :done
) else (
rem wait for 1 minute then try again
timeout /t 60 /nobreak
goto :start
)
)
:done
endlocal
我建议将此编辑纳入DavidPostill的答案中，但我不知道为什么它未被批准...
findstr是多么的错误和错误……太糟糕了！不好意思，微软？DavidPostill肮脏的小技巧让我印象深刻，以完成工作。
有一种更简单的方法来检查电池电量。在导航区域中，将鼠标放在电池图标上，它将给出一个百分比。
