This article is your complete guide to sleep vs hibernate for your computer. The main difference between hibernate and sleep mode is the way your data is saved while your computer screen shuts down. When your computer hibernates, it also shuts completely off, which saves you energy in the long run! But, we are here to explain the full difference between sleep vs hibernate so keep reading!

What is the Difference Between Sleep and Hibernate?
Sleep and hibernate are two different power-saving modes available on computers that serve distinct purposes. Computer hibernate vs sleep can be distinguished by what happens with your data when the screen of your computer is off. Both modes use different functions and energy levels, but are sometimes misunderstood due to how close they are in name.
- Sleep: Low power consumption, quick resume, best for short breaks.
- Hibernate: No power consumption, slower resume, best for long breaks.
Sleep Mode:
- Power Usage: Sleep mode consumes a small amount of power. The computer enters a low-power state where the system’s state (open applications and documents) is kept in the computer’s RAM (random access memory).
- Resume Speed: Waking up from sleep mode is almost instant because the data is stored in RAM, which is very fast to access.
- Use Case: Sleep mode is ideal for short breaks or when you want to quickly resume your work.
Hibernate Mode:
- Power Usage: Hibernate mode uses no power. The computer saves the contents of its RAM to the hard drive or SSD and then completely powers down.
- Resume Speed: Waking up from hibernate mode takes longer than from sleep mode because the system needs to read the data back from the hard drive or SSD into RAM.
- Use Case: Hibernate mode is best for longer periods of inactivity, such as overnight or when you won’t be using the computer for an extended time.

Sleep Mode vs Hibernate Mode: Which is Better?
Sleep mode is overall the most common method of powering down your computer, and probably the best thing for it if you’re concerned about time. With that being said, if you happen to only have sleep mode and lose power, you could potentially lose data since it is only being stored in your memory with the screen is off.
How much power does sleep mode vs hibernate mode?
- Sleep mode – Laptop (1-2 watts), Desktop (3-10 watts)
- Hibernate mode – No usage of power
In the category of energy saving for PC sleep vs hibernate, hibernate uses no power, so therefore, it is more energy efficient. Sleep mode barely uses any energy, so we don’t consider it to be a make-or-break decision.
What is better for your laptop?
If you’re using a laptop, the most common default option will be the sleep mode. We also highly suggest using the sleep vs hibernate laptop function because of the battery life on the device. The sleep mode can be more quickly activated and used to extend battery life throughout the day and overnight.
Should I shut down my computer every night?
Since the newer computer’s idle/stand-by modes have improved greatly with efficiency, it is no longer necessary to completely shut off your computer every night. If you infrequently use your computer, unplugging it every night can save you a couple of dollars, but in the long run, not make that much of a difference. If you still have an older computer or laptop, you might potentially benefit from a complete shutdown to conserve energy.

Sleep Vs Hibernate FAQ
Q: What is the difference between sleep mode and hibernate mode?
A: Sleep mode puts your computer into a low-power state while preserving the current state in the RAM. Hibernate mode, on the other hand, saves the current state onto the hard disk and completely powers off the computer.
Q: Is hibernation better than sleep?
A: Hibernate is not better or worse than sleep mode, they both serve different functions for what you might need for your device. Sleep mode is better for frequent laptop users that need a quick start-up with their data ready to go for the next use. Hibernate mode is perfect for desktop users who might space out usage in between and are looking for a mode that uses no energy and saves all of their data.
Q: What is hibernate mode?
A: Hibernate mode is a power-saving mode that allows you to shut off your computer, but easily resume work with saved data. Hibernate mode differs from sleep mode, in that, your computer does turn off, but the data is stored on your hard drive. This allows you to step away from your computer for a longer amount of time, but still have your applications and files exactly where you left off!
