如果您使用的是 Windows 10 笔记本电脑，并且您想知道在备用电池上可以继续使用计算机多长时间，则在必须为其充电之前，您可以编辑注册表^(Registry)并让 Windows 10 显示剩余电池时间^{( remaining battery time)}。您可以在注册表编辑器^{(Registry Editor)}的帮助下启用此功能，因为它默认处于禁用状态。

当您在电池上使用 Windows 10 笔记本电脑时，您会看到一个百分比，表示剩余电池电量。确定您可以在不充电的情况下使用计算机的时间非常困难。但是，如果您启用了估计剩余时间功能，您可以知道您的计算机可以在不充电的情况下运行多长时间。

^(Show)在Windows 10中^{(Windows 10)}显示剩余电池时间^{(Battery Time)}

要在Windows 10^{(Windows 10)}中启用并显示剩余电池时间，请执行以下步骤：

1. 打开注册表编辑器
2. 导航到电源文件夹
3. 创建^(Create)和更改三个注册表^(Registry)项的值
4. 重启你的电脑。

在开始之前，请确保您已经创建了注册表文件备份^{(Registry file backup)}和系统还原点，这样您就可以确保安全。

现在，在您的计算机上打开注册表编辑器。并导航到这条路径-

Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power

选择电源^{(Power )}文件夹。现在您需要在右侧创建三个DWORD （32 位）值。^(DWORD)为此，请右键单击空白，选择New > DWORD（32 位）值。

将其命名为EnergyEstimationEnabled。在大多数Windows 10笔记本电脑中，该值应该已经存在。如果Power文件夹中已有此^(Power)DWORD（32 位）值，则不必再次创建它。

之后，再创建两个相同的值，并将它们命名为EnergyEstimationDisabled和UserBatteryDischargeEstimator。创建这三个之后，您必须设置Value Data。

您只需更改EnergyEstimationEnabled的值数据。默认情况下，它应该设置为0，但您需要将其更改为1。您可以双击它并按照所述设置值。

现在，等待一段时间，然后将鼠标悬停在任务^(Taskbar)栏中的电池图标上。如果几分钟后仍未显示，请重新启动计算机。

如果要禁用估计此电池剩余时间^{(Battery time remaining)}功能，您需要按如下方式设置值 -

• EnergyEstimationEnabled – 0
• EnergyEstimationDisabled – 1
• UserBatteryDischargeEstimator – 1

请^(Please)注意，当您的笔记本电脑连接到充电器时，您不会获得任何预计时间。

How to enable remaining Battery Time in Windows 10

If you are using a Windows 10 laptop and you want to know how long you can continue to use your computer on battery backup, before you have to charge it, you can edit thе Registry and make Windows 10 show the remaining battery time. You can enable this feature with the help of the Registry Editor as it is disabled by default.

When you are using your Windows 10 laptop on battery, you see a percentage that indicates the remaining battery charge. It is quite tough to determine how much time you can use your computer without charging. However, if you enable the estimated time remaining feature, you can know how much time your computer can run without charging.

Show remaining Battery Time in Windows 10

To enable and show the remaining battery time in Windows 10, follow these steps:

1. Open Registry Editor
2. Navigate to the Power folder
3. Create and change the value of three Registry keys
4. Restart your computer.

Before getting started, make sure that you have created a Registry file backup, and a System Restore point so that you can be on the safe side.

Now, open the Registry Editor on your computer. and navigate to this path-

Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power

Select the Power folder. Now you need to create three DWORD (32-bit) values on your right-hand side. To do so, right-click on white-space, select New > DWORD (32-bit) value.

Name it as EnergyEstimationEnabled. In most of the Windows 10 laptops, this value should already be present. If you have this DWORD (32-bit) value in the Power folder already, you do not have to create it again.

Following that, create two more same values, and name them as EnergyEstimationDisabled and UserBatteryDischargeEstimator. After creating these three, you have to set the Value Data.

You need to change the value data of EnergyEstimationEnabled only. By default, it should set to 0, but you need to change it to 1. You can double-click on it and set the value as mentioned.

Now, wait for some time before hovering your mouse on the battery icon in the Taskbar. If it is not being displayed even after a couple of moments, restart your computer.

If you want to disable estimated this Battery time remaining feature, you need to set the value as follows-

• EnergyEstimationEnabled – 0
• EnergyEstimationDisabled – 1
• UserBatteryDischargeEstimator – 1

Please note that you won’t get any estimated time when your laptop is connected to a charger.
