用了Windows7之后，和很多人一样，发现没法休眠了，合上显示器会自动进入关机状态，下次重启，现场都没有了。也耽误了不少事，后来研究了一下发现是可以启用休眠的（Hibernate），设置也很简单，第一次休眠重启失败，第二次OK。

进一步在电源选项中个性化设置没有成功，有搞定的网友给介绍吧。【更新：已经自然搞定，重启后，在电源选项中就自动出现了休眠选项】

1. Open Command Prompt with Administrator rights. To open Command Prompt, type CMD in Start menu and then hit Ctrl + Shift + Enter to open the Command Prompt with Admin rights.

2. Next, type the below command and hit enter: powercfg /hibernate on

3. Type exit and hit enter to close the Command Prompt.

4. If you can’t see the Hibernate option in Start menu then do the following tasks:

A. Type Power Options in Start menu and hit enter.

B. In the left pane, open the link labeled “Change when the computer sleeps” and then open the link “Change advanced power settings”.

C. Under the Advanced Sleep options, expand the Sleep tree and turn off Hybrid Sleep.

D. Now go back to Start menu to see the new Hibernate entry.
