有几个因素会导致设备的电池寿命变短^{(poor battery life of a device)}，但您可以配置计算机在屏幕关闭时如何使用电源，以帮助在Windows 10中节省电池电量。当我的屏幕关闭时，您需要使用停止设备来帮助节省电池^{(Stop devices when my screen is off to help save battery)}设置或编辑注册表。

^(Turn)屏幕^(Screen)关闭时关闭设备^(Devices)以帮助节省电池电量^(Off)

某些 Windows 10^{(Certain Windows 10)}设备允许您在屏幕关闭时停止USB设备，以帮助节省电池电量。您可以编辑注册表^(Registry)或通过设置^(Settings)进行如下操作：

1. 打开设置^(Settings)。
2. 选择设备^(Devices)。
3. 单击 USB。
4. 选中屏幕关闭时停止设备以帮助节省电池电量^{(Stop devices when my screen is off to help save battery)}。
5. 重新启动您的电脑。

让我们详细看看这个过程。

单击Windows图标，选择“设置^(Settings)”。

选择“设备^(Devices)”磁贴。

切换到右窗格并查找以下条目 - '当我的屏幕关闭时停止设备以帮助节省电池^{(Stop devices when my screen is off to help save battery)}'。

在Windows 10^{(Windows 10)}中选中标有它的框以节省电池寿命。

就是这样！

您还可以 在Windows 11或 Windows 10中编辑注册表。按^(Registry)Win+R组合键打开“运行”^(Run’)对话框。

在框的空白字段中输入“ Regedit ”，然后按“ ^(Regedit)Enter ”。

当注册表编辑器^{(Registry Editor)}打开时，导航到以下路径地址 -

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\USB\AutomaticSurpriseRemoval

现在，切换到右窗格并双击条目“ AttemptRecoveryFromUsbPowerDrain ”进行修改。

如果没有这样的条目，则创建一个新的32 位双字值AttemptRecoveryFromUsbPowerDrain。

请注意，即使您运行的是 64 位Windows，您仍必须创建 32 位DWORD值。

将^(Set)上述条目的值设置为1以启用该功能；否则，将其设置为0以禁用该功能。

重新启动^(Restart)Windows 11/10 以使更改生效。

Stop Devices when Screen is Off to help save battery in Windows 11/10

Therе аre several factors that contribute to the poor battery life of a device, but you can configure how your computer uses power when the screen is off to help save battery in Windows 10. You need to use the Stop devices when my screen is off to help save battery setting or edit the Registry.

Turn off Devices when the Screen is Off to help save battery

Certain Windows 10 devices let you stop USB devices when your screen is off, to help save battery. You can edit the Registry or you do it via Settings as follows:

1. Open Settings.
2. Choose Devices.
3. Click USB.
4. Check Stop devices when my screen is off to help save battery.
5. Restart your PC.

Let’s see the process in detail.

Click Windows icon, choose ‘Settings’.

Select the ‘Devices’ tile.

Switch to the right-pane and look for the following entry – ‘Stop devices when my screen is off to help save battery’.

Check the box marked against it to save the battery life in Windows 10.

That’s it!

You can also edit the Registry in Windows 11 or Windows 10. Press Win+R in combination to open the ‘Run’ dialog box.

Type ‘Regedit’ in the empty field of the box and press ‘Enter’.

When the Registry Editor opens, navigate to the following path address –

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\USB\AutomaticSurpriseRemoval

Now, switch to the right-pane and double-click the entry ‘AttemptRecoveryFromUsbPowerDrain’ to modify it.

If there’s no such entry create a new 32-Bit DWord value AttemptRecoveryFromUsbPowerDrain.

Kindly note that even if you are running 64-bit Windows you must still create a 32-bit DWORD value.

Set the value for the above entry to 1 to enable the feature; else, set it to 0 to disable the feature.
