世界一天比一天移动，为了跟上步伐，您需要电池供电。但它有一个限制，你需要一次又一次地给它充电，以保持它们的运行。尽管Windows有许多电源管理改进，并且虽然Windows 10/8/7中的电源效率诊断工具可以为您提供很多电源优化提示，但笔记本电脑的电池仍然没有我们希望的那么高效。它们只能最大保持 5-6 小时。那么，您想最大限度地提高电池的使用效率吗？

延长Windows笔记本电脑的电池^(Battery)寿命

诀窍是充分利用可用的电源。这里有一些技巧可以显着提高电池性能。

最常见的提示，如果您有时间只做一件事 -使用^(Use)省电^{(Power saver)}电源计划来最大限度地延长电池寿命。（要选择省电^(Power)计划，请在控制面板^{(Control Panel)}中打开电源选项^{(Power Options)}。）

其他一些有助于延长计算机电池寿命的方法：

1]选择省电的电源计划

电源计划是控制笔记本电脑如何管理电源的硬件和系统设置的集合。Windows有两个默认计划：

• 平衡^(Balanced)：在您需要时提供完整的性能和显示亮度，但在计算机空闲时节省电量。
• 省电^{(Power saver)}：延长电池寿命的最佳选择。成本？性能降低，显示亮度降低。
• 您的计算机制造商也可能会提供其他计划。

1. 要更改电源计划，请单击Windows任务栏通知区域中的电池计量器图标^{( battery meter icon)}。
2. ^(Battery)显示电源计划的 电池表。选择^{(Select one)}默认电源计划之一：Balanced或Power saver。 

   

3. 您还可以使用更多电源选项^{(using More power options)}创建自己的自定义节电计划。

2]降低显示亮度

显示器是计算机中最耗电的部分——甚至比硬盘和CPU还要多。大多数笔记本电脑都带有专用按键来控制显示屏的亮度和对比度。您还可以从控制面板^{(Control Panel)}中的电源选项^{(Power Options)}调整显示亮度。

3]减少^(Decrease)Windows变暗并关闭显示器的时间

您可以通过让Windows^(Windows)变暗然后在一段时间不活动后关闭显示器来节省电量。如果减少时间并提高电池的效率，则可以节省更多电量。

4]选择^(Choose)Windows何时变暗并关闭显示器

1. 单击通知区域中的电池^(battery)图标，然后单击更多电源选项^{(More Power Options)}。
2. 在选择^(Select)电源计划页面的左侧，单击选择何时关闭显示器^{(Choose when to turn off the display)}。 

   

3. 这样做只会为您当前使用的计划调整设置。要更改其他计划的设置，请单击要更改的计划旁边的更改计划设置。^(Change)
4. 单击保存更改^{( Save changes)}。

5]关闭^(Turn)或删除您不使用的设备

许多USB设备只需连接即可使用电源。如果您使用USB鼠标，您可以通过断开鼠标和使用触摸板来节省电量。如果您使用USB闪存驱动器，请在不使用时将其拔下。

6]关闭^(Turn)PC卡和集成无线设备

这些设备也使用电力。如果您不需要它们，请将它们关闭。

您可以使用Windows 移动中心^{(Windows Mobility Center)}来管理这些选项中的大部分。要打开WMC，请单击开始^{(Click Start)}并键入Windows 移动^{(Windows Mobility)}中心，然后单击第一个结果。

1] Choose a power-saving power plan

A power plan is a collection of hardware and system settings that control how your laptop manages power. Windows has two default plans:

• Balanced: Offers full performance and display brightness when you need it, but conserves power when the computer is idle.
• Power saver: The best choice for extending battery life. The cost? Slower performance and lower display brightness.
• Your computer manufacturer might offer additional plans as well.

2. Battery meter showing power plans. Select one of the default power plans: Balanced or Power saver. 

   

3. You can also create your own custom power saver plans by using More power options.

2] Reduce display brightness

3] Decrease time for Windows dims and turns off the display

You can save power by having Windows dim and then turn off the display after a period of inactivity. You can save more power if you decrease the time and increase the efficiency of the battery.

4] Choose when Windows dims and turns off the display

1. Click the battery icon in the notification area and click on More Power Options.
2. On the Select a power plan page, on the left, click Choose when to turn off the display. 

   

3. Doing this adjusts settings only for the plan that you’re currently using. To change settings for another plan, click Change plan settings next to the plan that you want to change.
4. Click Save changes.

5] Turn off or remove devices that you aren’t using

Many USB devices use power just by being connected. If you use a USB mouse, you can save power by disconnecting the mouse and by using a touchpad. If you use a USB flash drive, unplug it when you’re not using it.

6] Turn off PC cards and integrated wireless devices

These devices also use power. If you don’t need them, turn them off.

You can use Windows Mobility Center to manage most of these options. To open WMC, Click Start and type Windows Mobility center and click on the first result.
