Learn about Hybrid Sleep in Windows Vista and how to turn it on.
What Is Hybrid Sleep
Hybrid Sleep is a new sleep mode introduced in Windows Vista. Hybrid Sleep is a combination of standby and hibernation.
When a computer goes into hybrid sleep it creates a hibernation file and saves it on the hard drive. It also keeps a copy of the hibernation file in its memory and shuts down most of the components in your computer.
When you move your mouse or tap your keyboard to wake a computer in hybrid sleep it loads the hibernation file from memory and resumes what you were doing. If the computer lost power during hybrid sleep it loads the hibernation file that was saved on the hard drive.
Hybrid sleep is enabled on desktops but not laptops by default. You don’t want your laptop not fully shut down while it’s in your laptop’s bag. It’ll overheat and drain the battery.
Turn Hybrid Sleep On
- Type cmd in the Start Menu’s search box.
- Right-click cmd.exe in the search results and then select Run as administrator.
- Type powercfg –h on in the command prompt and then press enter on your keyboard.
Why Does Hybrid Sleep Turn Off
The most common cause for your computer to stop going into hybrid sleep is when you erase the hibernation file (Hibernation File Cleaner) in Disk Cleanup.
