If you're new to Windows 8, one thing you might have noticed is that the Power menu has no Hibernate option. You can click Sleep, Shut down, or Restart, but there's no longer an option to hibernate your machine.
Thankfully, it's fairly simple to restore that valuable option. Here's how:
1. You'll need to access your system's power settings, which you can do any number of ways. One way is to press Win-W (that's the Windows key and the letter w) to bring up the Settings Search menu, then type power.
2. Click Change what the power buttons do.
3. Click Change settings that are currently unavailable.
4. Scroll down to the bottom of that window to find the "Shutdown settings" section.
5. Click the box next to Hibernate to enable the option.
6. Click Save changes.
Now, when you go to power down your system, you'll see the Hibernate option in your list of choices. Also, in that same System Settings window (step 4), you can choose Hibernate for any of the "Power and sleep buttons and lid settings" options.
In other words, if you want your system to hibernate when you press the power button or close the lid, this is where you can configure that setting.
