查询 Windows 7 上的当前电源配置设置

Powercfg 允许使用来设置某些设置，例如monitor-timeout-ac和。是否可以查询这些设置的当前值？我查看了帮助文本，但没有找到通过命令的方法。也许还有其他命令可以提供当前状态？standby-timeout-dcpowercfg -change <setting> <value>powercfg

答案1

要查询有关您提到的特定设置的特定部分，请执行以下操作：

  • powercfg -list获取当前电源计划 GUID 列表。记下/复制您要查询的计划的 GUID。
  • powercfg -aliases获取计划子部分的 GUID 列表。注意/复制“SUB_SLEEP”和“SUB_VIDEO”的 GUID。
  • powercfg -query <GUID of power plan> <GUID of sub-section>。

“SUB-SLEEP”子部分的示例输出：

C:\Windows\system32>powercfg -query 8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c 238c9fa8-0aad-41ed-83f4-97be242c8f20

答案2

我没有足够的声誉来评论@randy 的优秀答案，但我想我会在最后为那些只想要十进制格式的时间的人添加一点点：

#Show Current Settings
$sleeptime = [uint32]"$sleepSettingTrimmed"
$hibtime = [uint32]"$hibernateSettingTrimmed"

if($sleepSettingTrimmed -eq "0x00000000")
{
Write-Host "Sleep is currently disabled on AC."
}
else
{
write-host "Time to Sleep on AC is currently $sleeptime seconds."
}

if($hibernateSettingTrimmed -eq "0x00000000")
{
Write-Host "Hibernation is currently disabled on AC."
}
else
{
write-host "Time to Hibernate on AC is currently $hibtime seconds."
}

答案3

是的。令人惊讶的是，它使用以下设置：

powercfg -query

以下是该命令的摘录powercfg -? |more：

POWERCFG <command line options>
Description:
  This command line tool enables users to control the power settings
  on a system.

Parameter List:
  -LIST, -L   Lists all power schemes in the current user's environment.

          Usage: POWERCFG -LIST

  -QUERY, -Q  Displays the contents of the specified power scheme.

          Usage: POWERCFG -QUERY <SCHEME_GUID> <SUB_GUID>

          <SCHEME_GUID>  (optional) Specifies the GUID of the power scheme
                         to display, can be obtained by using powercfg -l.
          <SUB_GUID>     (optional) Specifies the GUID of the subgroup
                         to display.  Requires a SCHEME_GUID to be provided.

          If neither SCHEME_GUID or SUB_GUID are provided, the settings
          of the current user's active power scheme are displayed.
          If SUB_GUID is not specified, all settings in the specified
          power scheme are displayed.

希望这可以帮助。 ：）

# get current power sleep time setting
# I know of no other way to return the single number of the sleep time
# (powershell)
# run script with "powershell -file" to get errorlevel set right

# (Balanced plan) (Sleep section)
# can't do (Sleep after subsection guid) too?
$result = powercfg -query 381b4222-f694-41f0-9685-ff5bb260df2e 238c9fa8-0aad-41ed-83f4-97be242c8f20

# line 8, 7th word, in hex, cast to decimal
[int64]$sleeptime = ($result[7] -split ("\s+"))[6]

# return sleep time in minutes in errorlevel
exit $sleeptime/60
