windows – Powershell Set Lid关闭动作

我希望自动设置Windows 7在我的工作笔记本电脑上关闭盖子时所采取的操作,因为每次登录时都会通过GPO重置.

我知道我可以在批处理脚本中使用powercfg命令来实现这个目的：

powercfg -setacvalueindex 5ca83367-6e45-459f-a27b-476b1d01c936 0
powercfg -setdcvalueindex 5ca83367-6e45-459f-a27b-476b1d01c936 0

然而,这是尝试学习一些PowerShell的一个很好的借口.我的第一次尝试需要10秒以上才能运行.

在运行时和运行方面,我如何改进以下内容？在清洁代码方面.接近下面的惯用PowerShell方法是什么？

$DO_nothing = 0

$activePowerPlan = Get-WmiObject -Namespace "root\cimv2\power" Win32_PowerPlan | where {$_.IsActive}
$rawPowerPlanID = $activePowerPlan | select -Property InstanceID
$rawPowerPlanID -match '\\({.*})}'
$powerPlanID = $matches[1]

# The .GetRelated() method is an inefficient approach,i'm looking for a needle and this haystack is too big. Can i go directly to the object instead of searching?
$lidCloseActionOnACPower = $activePowerPlan.GetRelated("win32_powersettingdataindex") | where {$_.InstanceID -eq "Microsoft:PowerSettingDataIndex\$powerPlanID\AC\{5ca83367-6e45-459f-a27b-476b1d01c936}"}
$lidCloseActionOnBattery = $activePowerPlan.GetRelated("win32_powersettingdataindex") | where {$_.InstanceID -eq "Microsoft:PowerSettingDataIndex\$powerPlanID\DC\{5ca83367-6e45-459f-a27b-476b1d01c936}"}

$lidCloseActionOnACPower | select -Property SettingIndexValue
$lidCloseActionOnACPower.SettingIndexValue = $DO_nothing
$lidCloseActionOnACPower.put()

$lidCloseActionOnBattery | select -Property SettingIndexValue
$lidCloseActionOnBattery.SettingIndexValue = $DO_nothing
$lidCloseActionOnBattery.put()

试试WMI加速器：

$class = ([wmi] '\root\cimv2\power:Win32_PowerSettingDataIndex.InstanceID="Microsoft:PowerSettingDataIndex\\{8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c}\\DC\\{5ca83367-6e45-459f-a27b-476b1d01c936}"')
$class.SettingIndexValue = 0
$class.Put()
