如何在运行 powershell 进程时阻止 Windows 10 计算机进入睡眠/休眠状态？

我有一个 powershell 进程，它从远程服务器读取记录并将其复制到本地数据库中。运行时，可能会运行 8-12 小时。

如何防止计算机在此期间关闭（或进入睡眠/休眠模式）？我知道我可以调整“电源和睡眠设置”以将计算机设置为从不睡眠，但这不是我想要的 - 我do希望它在进程时进入睡眠状态isn't跑步。

我知道如果 netflix 或 youtube 视频正在运行，睡眠/休眠会被暂停，我希望计算机在 powershell 进程运行时执行相同的操作。

powershell进程在桌面上的命令窗口中运行 - 我很高兴屏幕保护程序能够激活，但我不希望发生的是我在8小时后唤醒机器并发现该进程只运行了电脑进入睡眠状态前10分钟！

通过一些额外的努力，您可以通过以下方式实现所需的行为标准powercfg.exe utility https://learn.microsoft.com/en-us/windows-hardware/design/device-experiences/powercfg-command-line-options，通过使用定制、始终开启的电源方案它是按需创建的，并在脚本运行期间临时激活：

# Define the properties of a custom power scheme, to be created on demand.
$schemeGuid = 'e03c2dc5-fac9-4f5d-9948-0a2fb9009d67' # randomly created with New-Guid
$schemeName = 'Always on'
$schemeDescr = 'Custom power scheme to keep the system awake indefinitely.'

# Helper function that ensures that the most recent powercfg.exe call succeeded.
function assert-ok { if ($LASTEXITCODE -ne 0) { throw } }

# Determine the currently active power scheme, so it can be restored at the end.
$prevGuid = (powercfg -getactivescheme) -replace '^.+([-0-9a-f]{36}).+$', '$1'
assert-ok

# Temporarily activate a custom always-on power scheme; create it on demand.
try {

  # Try to change to the custom scheme.
  powercfg -setactive $schemeGuid 2>$null
  if ($LASTEXITCODE -ne 0) { # Changing failed -> create the scheme on demand.
    # Clone the 'High performance' scheme.
    $null = powercfg -duplicatescheme SCHEME_MIN $schemeGuid
    assert-ok
    # Change its name and description.
    $null = powercfg -changename $schemeGuid $schemeName $schemeDescr
    # Activate it
    $null = powercfg -setactive $schemeGuid
    assert-ok
    # Change all settings to be always on.
    # Note: 
    #   * Remove 'monitor-timeout-ac', 'monitor-timeout-dc' if it's OK
    #     for the *display* to go to sleep.
    #   * If you make changes here, you'll have to run powercfg -delete $schemeGuid 
    #     or delete the 'Always on' scheme via the GUI for changes to take effect.
    #   * On an AC-only machine (desktop, server) the *-ac settings aren't needed.
    $settings = 'monitor-timeout-ac', 'monitor-timeout-dc', 'disk-timeout-ac', 'disk-timeout-dc', 'standby-timeout-ac', 'standby-timeout-dc', 'hibernate-timeout-ac', 'hibernate-timeout-dc'
    foreach ($setting in $settings) {
      powercfg -change $setting 0 # 0 == Never
      assert-ok
    }
  }
  
  # YOUR CODE GOES HERE.
  # In this sample, wait for the user to press Enter before exiting.
  # Before that, the 'Always on' power scheme should remain in
  # effect, and the machine shouldn't go to sleep.
  pause

} finally { # Executes even when the script is aborted with Ctrl-C.
  # Reactivate the previously active power scheme.
  powercfg -setactive $prevGuid
}

你可以创建一个wrapper上面的脚本，您可以将要执行的脚本的路径传递给该脚本。

如果您不介意修改目前活跃 scheme，您可以使用中所示的方法克尔的回答 https://stackoverflow.com/users/3996028/kerr，使用每个设置powercfg -change <setting> <value-in-minutes> calls (/x / -x是一个别名/change / -change），使用以下之一<setting>每次通话中的姓名；通过0 as <value-in-minutes>代表never:

• monitor-timeout-ac
• monitor-timeout-dc
• disk-timeout-ac
• disk-timeout-dc
• standby-timeout-ac
• standby-timeout-dc
• hibernate-timeout-ac
• hibernate-timeout-dc

但请注意，这些变化是执着的, so 你可能想要restore稍后的原始值，这需要额外的努力。
