当您离开计算机时，您多久考虑一次计算机的电源使用情况？尽管计算机已经变得非常节能，但它们仍然可能是耗电大户。因此，当您不使用计算机时，您可能希望将其关闭。
然而，事情并没有那么简单。现代计算机可以使用几种不同的“关闭”变体。睡眠(Sleep)和休眠是您在告诉计算机小睡时会看到的两个选项。但是睡眠和休眠有什么区别呢？它们听起来当然是同一类东西！
这两个选项之间实际上存在显着差异。这会对您的电费和数据完整性产生影响。
基线：关闭计算机(Computer)
让我们从最基本的开始：关闭。当您关闭计算机时，所有RAM都会被清空。计算机关闭其所有组件并且不消耗电力。拔掉它是安全的。这与您的计算机一样“关闭”。
主要的缺点是您必须以“冷”启动方式启动计算机。您必须启动操作系统、登录并打开您的应用程序。如果您只想从中断的地方继续，这是最不方便的选择。
入睡：啜饮电源
睡眠模式可能是人们“关闭”计算机最流行的方式。睡眠模式的作用是关闭计算机组件或将其切换到低功耗状态。最重要的需要电源的硬件是RAM。这是因为这种快速的计算机内存需要持续的电源来保存其内容。切断电源，RAM中的数据就会变糟！
这就是睡眠模式的第一个主要弱点。如果您的计算机因任何原因断电，您将无法从睡眠中恢复！在某些情况下，这甚至会导致启动问题，因为在断电之前计算机没有正确关闭。
笔记本电脑显然根本没有这个问题。因为在断电的情况下，板载电池将继续为睡眠中的计算机供电。但是，您可能需要考虑使用UPS（不间断电源）来保证睡眠中的计算机安全，以防万一。
睡眠模式的第二大警告是它仍然使用电力。可以肯定的是，它比活动计算机使用更少的电力。通常只有几个个位数的瓦特。然而，这确实会在数天、数周和数月内加起来。
睡眠模式的最大便利是您的计算机几乎可以立即工作。移动鼠标或打开笔记本电脑盖，您就可以开始使用了。
冬眠：长期(Long Haul)寒冷(Cold)
休眠(Hibernation)还可以让您打开计算机电源并从上次中断的地方继续。这里最大的区别是内存的内容存储在硬盘上。这是非易失性存储器，因此即使在断电时也能保存您的数据。
将RAM(RAM)中的内容完全保存到硬盘驱动器后，您的计算机就可以完全关闭电源。它可以拔出和运输，完全没有后顾之忧。在这种情况下，停电也无关紧要。
那么，有什么问题呢？从休眠模式恢复比睡眠模式慢。计算机必须从冷态启动，然后将RAM的内容从硬盘复制回来。
问题是，现代计算机从冷启动非常快。此外，如果您的计算机有SSD作为主驱动器，尤其是NVME型号，则可以将RAM映像复制到闪存中。因此，虽然从休眠中恢复可能不如从睡眠中恢复快，但两者之间的差距已经明显缩小。这也意味着进入休眠状态比进入睡眠状态需要更长的时间，但从用户的角度来看，这并没有太大的区别。
混合睡眠选项
您可能可以使用的第三种选择称为混合睡眠。这里发生的是计算机进入正常睡眠模式，但它也会将RAM的副本保存到硬盘驱动器。当您恢复时，就像从睡眠模式恢复一样。但是，如果计算机在睡眠时断电，它会像从休眠状态恢复一样启动。
因此，通过混合睡眠，您可以两全其美，但这里没有免费搭车！那是因为进入混合睡眠比正常睡眠需要更长的时间。尽管差异对您来说不一定重要。第二个缺点是它使用与正常睡眠模式完全相同的电量。因此，您不会获得从休眠中获得的节能优势。
在Windows 10中激活不同的睡眠(Different Sleep) 选项(Options)
现在您已经了解了Windows 10(Windows 10)中睡眠和休眠之间的区别，是时候真正学习如何在它们之间进行切换了。当您将系统置于待机状态时，您需要告诉Windows它应该使用什么类型的模式。(Windows)这是如何做到的：
- 选择开始按钮(Start Button)
- 选择齿轮图标(cog icon)
- 选择系统(System)
- 选择电源和睡眠(Power and Sleep)
- 选择其他电源设置(Additional power settings)
- 选择选择电源按钮的功能(Choose what the power buttons do)
现在你可以做几件事：
- 使电源按钮进入睡眠、休眠或关闭屏幕而不是关机
- 让睡眠按钮休眠或关闭屏幕
- 将(Add)休眠作为选项添加到电源菜单
混合睡眠呢？让我们看看如何打开或关闭它。从上面执行相同的步骤 1 到 5。
- 选择开始按钮(Start Button)
- 选择齿轮图标(cog icon)
- 选择系统(System)
- 选择电源和睡眠(Power and Sleep)
- 选择其他电源设置(Additional power settings)
6.在您当前选择的电源计划上选择更改计划设置(Change plan settings)
7.选择更改高级电源设置(Change advanced power settings)
在高级(Advanced)设置下，您会看到一个功能列表，每个功能旁边都有一个小加号图标。展开睡眠(Sleep)，然后展开允许混合睡眠(Allow hybrid sleep)。将设置更改为您喜欢的设置。
哪种电源模式适合您？
虽然这听起来有点复杂，但实际上很容易为各种用户环境推荐特定的电源设置。如果您经常使用笔记本电脑，那么只需使用普通睡眠模式即可。板载电池使人们对断电的担忧变得多余。如果您打算将笔记本电脑放置很长时间并且不想耗尽电池电量，那么休眠当然是一种选择。但是，您可能不需要恢复几周或几个月前的会话。
如果您使用的是台式计算机，如果您不介意在计算机不使用时烧掉几瓦，我们建议您使用混合睡眠。
如果您正在寻找最大程度的节能，请在您的台式计算机上使用休眠模式。只要您不要太在意坐下来重新开始工作时稍长的启动时间。
What Is the Difference Between Sleep and Hibernate in Windows 10?
How often do you think about thе power usage оf your computer when you’re away from it? While computers have become prеtty power-efficient they can still be significant power hogs. So when you’re not usіng your computer, you might want to switch it off.
However, things aren’t that simple. There are several different variants of “off” that a modern computer can use. Sleep and hibernation are two of the options you’ll see when telling your computer to take a nap. But what’s the difference between sleep and hibernate? They certainly sound like the same sort of thing!
There’s actually a significant difference between these two options. Which can make a difference to both your power bill and data integrity.
The Baseline: Shutting Down Your Computer
Let’s start with the very basics: shutting down. When you shut down your computer, all of the RAM is emptied. The computer turns all of its components off and it draws no power. It’s safe to unplug it. This is as “off” as your computer can be.
The main downside is that you have to start up the computer in a “cold” boot. You’ll have to start up your operating system, login and open your applications. If you just want to pick up from where you left off, this is the least convenient option.
Going To Sleep: Sipping On Power
Sleep mode is probably the most popular way for people to turn their computers “off”. What sleep mode does is to either turn off or switch the computer’s components into a low power state. The most important bit of hardware that needs power is the RAM. That’s because this fast computer memory needs a constant supply of power to preserve its contents. Cut the power off and the data in RAM goes poof!
Which is where the first major weakness of sleep mode comes into the picture. If your computer loses power for any reason, you can’t resume from sleep! In some cases this can even lead to startup issues, since the computer was not properly shut down before the power loss.
Laptop computers obviously don’t have this problem at all. Since the on-board batteries will keep supplying power to the sleeping computer in the event of power loss. However, you may want to consider using a UPS (uninterruptible power supply) to keep your sleeping computer safe just in case.
The second big caveat with sleep mode is that it still uses power. To be sure, it uses less power than an active computer. Usually just a few, single-digit watts. That does add up over days, weeks and months however.
The big convenience with sleep mode is that your computer is ready to work almost instantly. Move the mouse or open the laptop lid and you’re ready to go.
Hibernation: Going Cold For The Long Haul
Hibernation also lets you power on your computer and pick up from where you left off. The big difference here is that the contents of your memory are stored on your hard drive. This is non-volatile memory and so keeps your data even when the power is off.
With the contents of RAM completely saved to the hard drive, your computer can power off completely. It can be unplugged and transported with no worries at all. A power cut also doesn’t really matter in this case.
So, what’s the catch? Resuming from hibernation is slower than sleep mode. The computer has to boot from a cold state and then copy the contents of RAM back from your hard drive.
The thing is, modern computers boot from cold very quickly. In addition, if your computer has an SSD as a main drive, especially an NVME model, the RAM image can be copied in a flash. So though resuming from hibernation might not be as quick as resuming from sleep, the gap between the two has narrowed significantly. It also means that going into hibernation takes longer than going to sleep, but from a user perspective that doesn’t make a lot of difference.
The Hybrid Sleep Option
A third option that may be available to you is known as hybrid sleep. What happens here is that the computer goes into a normal sleep mode, but it also saves a copy of your RAM to the hard drive. When you resume, it’s just like resuming from sleep mode. However, if there was a power cut while the computer was sleeping, it would boot up as if resuming from hibernation.
So with hybrid sleep you get the best of both worlds, but there’s no free ride here! That’s because it takes longer to enter hybrid sleep than normal sleep. Though the difference won’t necessarily matter to you. The second downside is that this uses exactly the same amount of power as normal sleep mode. So you don’t get the power savings benefit that you get from hibernation.
Activating Different Sleep Options in Windows 10
Now that you know the difference between sleep and hibernate in Windows 10, it’s time to actually learn how to switch between them. You need to tell Windows what type of mode it should use when you put the system on standby. Here’s how to do it:
- Select the Start Button
- Select the cog icon
- Select System
- Select Power and Sleep
- Select Additional power settings
- Select Choose what the power buttons do
Now you can do a couple of things:
- Make the power button sleep, hibernate or switch off the screen instead of shutting down
- Make the sleep button hibernate or turn off the screen instead
- Add hibernate as an option to the power menu
What about hybrid sleep? Let’s see how to turn it on or off. Follow the same steps 1 thru 5 from above.
- Select the Start Button
- Select the cog icon
- Select System
- Select Power and Sleep
- Select Additional power settings
6. Select Change plan settings on your currently selected power plan
7. Select Change advanced power settings
Under the Advanced settings, you’ll see a list of features with a little plus icon next to each. Expand Sleep and then expand Allow hybrid sleep. Change the settings to whichever you’d prefer.
Which Power Mode Is Right For You?
While this might all sound a little complicated, it’s actually pretty easy to recommend specific power settings for various user contexts. If you’re using a laptop on a regular basis, then simply use plain sleep mode. The onboard battery renders fears about power cuts redundant. If you’re going to put the laptop away for a long time and don’t want to drain the battery, hibernation is of course an option. However, you probably have no need to resume a session that’s weeks or months old.
If you’re using a desktop computer, we’d recommend hybrid sleep if you don’t mind burning through a few watts when the computer isn’t in use.
If you’re looking for maximum power savings, use hibernation on your desktop computer. As long as you don’t care too much about the slightly longer startup time when you sit down to get back to work.
