Sleep睡眠

Sleep uses very little power, your PC starts up faster, and you’re instantly back to where you left off. You don’t have to worry that you'll lose your work because of your battery draining because Windows automatically saves all your work and turns off the PC if the battery is too low. Use Sleep when you’re going to be away from your PC for just a little while—like when you’re taking a coffee break.
睡眠使用很少的电力，你的电脑启动更快，你立即回到你离开的地方。你当你要离开电脑一小段时间时，比如你喝咖啡休息的时候，使用睡眠。

For a lot of PCs (especially laptops and tablets), your PC goes to sleep when you close your lid or press the power button.
对于许多PC（特别是笔记本电脑和平板电脑），当您合上盖子或按下电源按钮时，您的PC会进入睡眠状态。

Hibernate休眠
