I had setup Hybrid sleep mode on my Windows 7 computer which comes with the Intel i5 460m and 6GB RAM. I was able to restore any opened documents and programs from hard disk and resume my workd quickly if a power failure occured. However, after the device upgraded to Windows 10 and install the anniversary update, the Hybrid sleep is missing and will not work automatically.
As a power-saving state, Hibernate function is not supported with PCs with InstantGo, and is designed primarily for laptops and tablets. The Anniversary Update might casues the Hibernate feature to be turned off completely. You could enable it again via the command in Windows 10.
* From your desktop, hold-and-press or right click on Start menu, choose “Command Prompt (Admin)” option from menu.
* Type in the command below:
powercfg -h on
and press Enter to execute it and enable Hibernate.
Then make changes with Advanced Power Settings of a Power Plan.
* From your desktop, tap or click on the Start menu, input Power Options into search box, select “Power Options” from the search results.
* In Control Panel, check the Balanced(recommended) box, click on the Change Plan settings link to its right of Balanced plan.
* Set the Plugged in sleep time to 5 minutes or others to suite your needs, and click Save Changes.
* Click on “Change advanced power settings” link at the bottom.
* In the pop-up Power Options panel, click on the + mark next to the left side of Sleep, click on the + mark to the left of Hibernate, and Change the Plugged in: entry to 10 Minutes.
* Click OK button, close all related dialogs and reboot the system. Works for me.
However, if the Hibernate sleep mode is still not working in Windows 10, you need to boot to BIOS menu and check “S” mode. Otherwise the BIOS version is too old.
