Windows Vista system sleep function

        Some friends who use Windows Vista want to save disk space, use the command at the command prompt to turn off hibernation. But if you use the same method to turn on the hibernation function, you will find that even if the function is restored, the "hibernate" menu is still invisible. What is going on? Let's talk about this issue carefully.


































We can also check the "Hibernate File Cleaner" checkbox when cleaning up the disk.
However, if you run "powercfg -h on" again to enable hibernation, you will find that the hiberfil.sys file has been reproduced in the root directory of the system disk, but there is no "sleep" in the "Shutdown" drop-down menu. The option, and the "Shutdown" drop-down menu in the lower right corner of the page called by the "Ctrl+Alt+Del" key combination does not have the "Sleep" option. And we execute "powercfg -a" at the command prompt to confirm that the machine has enabled hibernation. So, how can we make the "hibernate" command in the shutdown menu revisit the day?
In fact, after executing the "powercfg -h on" command, there is no "hibernation" option in the "shutdown" menu, because Windows The Vista operating system automatically enables the "hybrid sleep" mode. We can solve the problem as follows.


From the control panel, select System and Maintenance→Power Options→Change Schedule Settings→Change Advanced Power Settings, select Allow Mixed Sleep in the Sleep list, and then set this option to "Close" (as shown in the figure), after confirming, you can re-display the "hibernation" in the shutdown menu. Friends who need this aspect may wish to try.
