如今，一个家庭中有这么多手机和笔记本电脑，实际上不可能为每台设备配备一个电源插座。如果您发现插头短缺，一种简单的方法是将智能手机连接到笔记本电脑并为其充电——即使笔记本电脑盖合上。虽然每台“唤醒”的笔记本电脑都可以为手机充电，但即使它没有插入电源插座，但当笔记本电脑盖合上笔记本电脑进入睡眠模式时，情况就不一样了。

您知道即使笔记本电脑盖合上，您也可以在睡眠模式下为手机充电^{(charge your mobile phone in sleep mode even when the laptop lid is closed)}？在这篇文章中，我们将了解如何在笔记本电脑盖合上的情况下为手机充电，并了解如何更快地为手机充电。

笔记本电脑在开机时会为您的手机充电，一旦您合上盖子或将其置于睡眠状态，充电就会停止。您可能不知道，但即使笔记本电脑盖合上，您仍然可以继续为手机充电。

在笔记本电脑^(Laptop)盖关闭的情况下，在睡眠模式下为^{(Sleep Mode)}手机^(Phone)充电

要在笔记本电脑盖关闭且没有充电器的情况下在睡眠模式下为手机充电，您必须打开设备管理器^{(Device Manager)}并取消选中允许计算机关闭此设备以节省电源^{(Allow the computer to turn off this device to save power)}选项。让我们详细看看如何做到这一点。

首先，打开笔记本电脑的设备管理器^{(Device Manager)}。右键单击Windows 0中的开始按钮^{(Start Button)}并选择设备管理器^{(Device Manager)}。否则^(Else)在搜索框中输入“设备管理器”，然后按 Enter^(Enter)。

转到通用串行总线控制器^{(Universal Serial Bus Controller )}以查看 USB 根集线器列表。

右键单击它们中的每一个，然后选择Properties > Power Management选项卡。

取消选中允许计算机关闭此设备以节省电源^{(Allow the computer to turn off this device to save power )}复选框。

这应该有效。

如果这种方法没有帮助，您可能需要检查笔记本电脑BIOS 系统中的USB支持。在某些笔记本电脑中，默认情况下禁用USB 唤醒支持^{(USB Wake Support)}，您需要启用它才能在笔记本电脑盖关闭的情况下在睡眠模式下为手机充电。

更快为手机充电的提示

尽管将手机插入笔记本电脑或台式机是一种非常缓慢的智能手机^(Smartphone)电池充电方式，但您仍然可以按照以下提示更快地充电：

• 任何设备，包括手机和平板电脑，在关闭时都能快速充电。充电前先关掉手机，看看有什么不同。
• 如果没有，请确保您的手机上没有启用互联网，如果您真的想更快地为它充电。您还可以将其置于飞行模式以快速充电。
• PC 的USB端口具有不同的功率容量。虽然USB 1.0 和 2.0 指定为 2.5W，但^(USB)USB 3.0为 4.5W 。因此，如果您想更快地为手机充电，请始终使用USB 3.0 。

保持设备正确充电以延长电池寿命始终非常重要。看看如何优化笔记本电脑的电池。 ^{(how to optimize a laptop battery. )}

How to charge your Phone in Sleep Mode with the Laptop lid closed

With so many mobile phones and laptopѕ in a family these days, it is not really possible to get a power outlet for every dеνice. If you find that there is а shortаge of plugs, one еasy way is to connect your smartphone to your laptop and get it charged – even when the laptop lid is closed. While every laptop that’s “awake” can charge a mobile phone, even if it isn’t plugged into thе power outlet, it is different when the laptop lid is closed and the laptop enters Sleep mode.

Do you know that you can charge your mobile phone in sleep mode even when the laptop lid is closed? In this post we will learn about how to charge your phone even with the laptop lid is closed and take a look at how to charge your phone faster.

A laptop charges your mobile phone when it is turned ON and as soon as you close the lid or put it to sleep, the charging stops. You probably don’t know, but you can still keep charging your phone even when your laptop lid is closed.

Charge Phone in Sleep Mode with Laptop lid closed

To charge a mobile phone in sleep mode with the laptop lid closed, without a charger, you have to open Device Manager and uncheck Allow the computer to turn off this device to save power option. Let us see how to do it in detail.

First, open the Device Manager of your laptop. Right-click the Start Button in Windows 0 and select Device Manager. Else type ‘device manager’ in the search box and hit Enter.

Go to the Universal Serial Bus Controller to see a list of USB Root Hub.

Right-click on each one of them and select Properties > Power Management tab.

Uncheck the Allow the computer to turn off this device to save power box.

This should work.

If this method doesn’t help, you probably have to check the USB support in your laptop’s BIOS system. In some laptops USB Wake Support is disabled by default, and you need to enable it to charge your phone in sleep mode with the laptop lid closed.

Tips on charging the phone faster

Though plugging your phone into a laptop or a desktop is a very slow way to charge your Smartphone battery, you can still get it a bit faster by following these tips:

• Any device, including mobile phones and tablets, charge super fast when turned off. Switch off your phone before you put it on charging and see the difference.
• If not, make sure that the internet is not enabled on your phone, if you actually want to charge it faster. You can also put it on flight mode to get fast charging.
• A PC’s USB ports are specified at different power capacities. While USB 1.0 AND 2.0 are specified at 2.5W, it is 4.5W for USB 3.0. So always used USB 3.0 if you want to charge your phone faster.

It is always very important to keep your devices properly charged for better battery life. Take a look at how to optimize a laptop battery.
