![]() ![]() Your video card may not support Sleep mode.When power resumes, Windows can restore your work from the hard disk if the memory is not accessible. Hybrid Sleep mode is useful for desktop computers in case of a power outage. When enabled, it automatically puts your computer into Hybrid Sleep mode when you put it into Sleep mode. The Hybrid Sleep mode is enabled by default in Windows on desktop computers and disabled on laptops. It puts any open documents and applications in memory and on your hard disk, and then puts your computer into a low-power state, allowing you to quickly wake the computer and resume your work. Hybrid Sleep mode is a combination of the Sleep and Hibernate modes meant for desktop computers. RELATED: How to Make Windows Hibernate More Often (Instead of Sleep) What Is Hybrid Sleep? Use hibernate mode if you won’t be using your laptop for an extended period of time, and you don’t want to close your documents. Modern SSDs - especially PCIe NVMe SSDs - are blazing fast, and it really shows when you’re using hibernate. Sleep mode used to be much faster than hibernation, since hibernation was limited by the speed of a mechanical hard disk. ![]() It just takes a bit longer to resume than sleep mode does. Once the computer is powered back on, it will resume everything where you left off. This allows your computer to turn off entirely, which means once your computer is in hibernate mode, it uses zero power. Hibernate mode is very similar to sleep, but instead of saving your open documents and running applications to your RAM, it saves them to your drive. RELATED: PSA: Don't Shut Down Your Computer, Just Use Sleep (or Hibernation) The computer doesn’t use much power in Sleep mode, but it does use some. And sleep (also called standby or suspend-to-RAM) is the S3 power state.Sleep mode is useful if you want to stop working for a short period of time. In the Advanced Configuration and Power Interface (ACPI) specification, hibernation is called suspend-to-disk and is the S4 power state in the standard. It hence takes less time to write to disk and resume. Hybrid Boot mode where the user is logged out before hibernating, thereby drastically reducing the size of the hibernation. During a complete power loss (power outage scenario), when RAM is offline, data is retrieved from the hard drive. The restart is faster (contents retrieved from RAM) and with minimal power loss. Hybrid Sleep mode is a mix of sleep mode and hibernate, where the contents are stored in RAM and hard drive. Some of the options available for Hibernate and Sleep in various OS are: Hibernate is defined as S4 in ACPI and sleep as S3. Hibernate and Sleep modes are supported in all operating systems where ACPI is supported. A hibernating system uses no power at all while a system in sleep mode consumes small but continuous power.Ī speed test of switching from sleep/hibernate mode to resume mode is performed in this video: Power consumption: Lower in hibernate mode.But a hibernating system needs comparatively more time to resume as it needs time to read back the data from the hard disk or other permanent memory storage. In sleep mode, since the data is stored in RAM, the resumption is immediate and no time is lost. In case of a power outage, any unsaved data is lost and cannot be recovered. In sleep mode, the data is still in the RAM, which is volatile. ![]() During hibernation, data is automatically stored in a non-volatile memory before the hardware shuts down.
