Sleep and hibernate are two power-saving states for computers, designed to conserve energy when the device is not in use. Sleep mode uses very little power and allows for a quick start-up, making it ideal for short breaks. On the other hand, hibernate mode saves your work to the hard drive and consumes no power, but it takes longer to resume. The choice between sleep and hibernate depends on how long you plan to be away from your device and your preference for a faster restart or better power conservation.
Sleep vs Hibernate
| Characteristics | Sleep | Hibernate |
|---|---|---|
| Power Consumption | Very little power | No power |
| Speed | Faster startup | Slower startup |
| Resume | Instantly back to where you left off | Back to where you left off |
| Usage | Short breaks | Extended breaks |
| Battery Drain | Possible | Not possible |
| Hybrid Mode | Enabled by default on desktops | Disabled by default on laptops |

What You'll Learn
Hibernation saves battery but takes longer to start up
Hibernate mode saves your computer's memory state to its hard drive, allowing it to turn off entirely and consume zero power. This makes hibernation an excellent option for saving battery power, especially for laptops that aren't plugged in. When you start up your device again, it will resume everything where you left off, but this process takes longer than resuming from sleep mode.
Sleep mode, on the other hand, saves your current work to your computer's RAM and keeps the device in a low-power state. It uses very little power, allowing your PC to start up faster and instantly return to where you left off. Sleep mode is ideal when you plan to be away from your device for a short period, such as during a coffee break.
The choice between hibernation and sleep mode depends on your specific needs. If you want to conserve battery power and won't be using your device for an extended period, hibernation is the better option. However, if you want faster startup times and will only be away for a short while, sleep mode is more suitable.
It's worth noting that some PCs or software may encounter issues when resuming from hibernation. In such cases, you might need to shut down or restart your computer instead. Additionally, you can set your device to automatically switch to hibernation mode after being in sleep mode for a certain period, ensuring that your battery doesn't drain if you don't use your device for several days.
By understanding the differences between hibernation and sleep modes, you can make informed decisions about when to use each option to optimise your device's performance and battery life.

Sleep mode is faster but consumes more power
Sleep mode and hibernation mode are two different power states for computers. Sleep mode is a power-saving state that is similar to pausing a DVD movie. All actions on the computer are stopped, any open documents and applications are put in memory while the computer goes into a low-power state. The computer technically stays on and uses very little power, allowing you to quickly resume normal, full-power operation within a few seconds. Sleep mode is useful when you're going to be away from your PC for a short while, such as during a coffee break.
Hibernation mode, on the other hand, saves your current work to your hard drive or SSD and consumes no power. The computer turns off entirely, and when powered back on, it resumes where you left off. Hibernate mode is useful when you know you won't be using your laptop or tablet for an extended period and won't have an opportunity to charge the battery during that time.
While sleep mode uses slightly more power than hibernation mode, it offers faster startup times. Sleep mode is designed for short periods of inactivity, allowing you to quickly resume your work. It is a good option when you need to step away from your computer for a short break but want to instantly get back to your work when you return.
The choice between sleep and hibernation mode depends on your specific needs and usage patterns. If you require instant access to your work and don't want to wait for the computer to power up, sleep mode is a suitable option. However, if you want to conserve battery power and don't mind a slightly slower startup time, hibernation mode is the better choice.
Additionally, it's worth noting that modern SSDs have significantly improved the speed of hibernation mode. The advancements in SSD technology, especially PCIe NVMe SSDs, have made the difference in resume times between sleep and hibernation modes less noticeable.

Hibernate is better for suspending games
Hibernate mode is better for suspending games. While sleep mode saves your current work to RAM, hibernate saves your current work to your hard drive or SSD, and consumes no power. This means that hibernate allows your computer to turn off entirely, and once powered back on, it will resume everything where you left off.
Sleep mode is a power-saving state that is similar to pausing a DVD movie. All actions on the computer are stopped, and any open documents and applications are put in memory while the computer goes into a low-power state. However, sleep mode is not as reliable as hibernate mode when it comes to suspending games. Some games may crash or stop working when you switch to Desktop and then switch back.
For example, one user reported that Spider-Man from the Epic Games Store crashed multiple times when trying to use sleep mode, while hibernate mode worked without issues. Another user reported that waking their computer from sleep mode caused the frame rate of Far Cry 6 to drop significantly, while hibernate mode caused no issues.
Hibernate mode is also useful if you won't be using your laptop for an extended period and won't have an opportunity to charge the battery. It is worth noting that hibernate mode takes longer to resume than sleep mode, but it is still a better option for suspending games.

Sleep is better for short breaks
Sleep mode is ideal for short breaks, such as a coffee break. It uses very little power, and your PC starts up faster, instantly taking you back to where you left off. This mode is perfect if you need to step away from your computer for a short period, as it saves your current work to RAM, allowing your computer to continue drawing a small amount of power while in sleep mode.
Sleep mode is a power-saving state similar to pausing a DVD movie. All actions on the computer are stopped, and any open documents and applications are put into memory while the computer enters a low-power state. The computer technically stays on, using minimal power, and you can quickly resume normal, full-power operations within a few seconds.
Sleep mode is also a good option if you need to take a short break from a game. Some games may not work as well when switching to desktop and then back, and sleep mode can be a good solution for this.
Additionally, sleep mode is useful if you want to keep your laptop connected to WiFi while taking a short break. Your laptop will remain connected to WiFi when you resume from sleep mode, which is not always the case with hibernation.
In summary, sleep mode is designed for brief periods away from your computer, allowing you to quickly resume your work or activities with minimal disruption.

Hibernation is similar to a regular shutdown
Hibernation and regular shutdown are similar in that they both allow your computer to turn off entirely, using zero power. When you hibernate your computer, it saves your current work to your hard drive or SSD, and when you start up your computer again, you're back to where you left off.
Hibernation is also similar to a regular shutdown in that it allows your computer to turn off entirely, and your computer will resume more quickly from hibernation than from a full shutdown. In addition, hibernation uses less power than sleep mode, which is another option for powering down your computer. With sleep mode, your computer continues to draw a small amount of power to keep its memory active, so you can quickly resume normal operation.
Hibernation is a good option if you won't be using your laptop for an extended period and won't have an opportunity to charge the battery. It's also useful if you want to save battery power on a laptop that isn't plugged in. If you know you'll be back to your computer shortly, sleep mode is a better option.
To hibernate your PC, you can press the Windows logo key + X on your keyboard, and then select "Shut down or sign out" > "Hibernate." You can also set your computer to hibernate automatically after a certain number of hours of sleep. For example, you can set your computer to sleep when you close the lid and then hibernate after a few hours of inactivity.
