There are subtle difference between a hibernate and sleep mode, but both share the same purpose. I guess few people would have ever used the hibernate mode as much as they use the Sleep mode. The fact is computers can sleep, hibernate, and shutdown, depending on the external command or users intent.
As we know, computers are subservient, meaning, they do not complain of what an operator commands. So, It’s up to users how they save power, especially when a power adapter is not plugged in.
It doesn’t matter which mode you choose, as every mode has some sort of disadvantages, so let’s try to understand that.
Sleep vs. Hibernate
- Sleep – The sleep mode sends your pc to the low-power state, keeping a PC’s state in Memory while shutting down the other parts so that no power can be used. It clasps backs to life after you tap on the power button or open the lid up, without having you to boot up. Your previous apps or any running tasks will be right there from where you left off
- Hibernate – In Hibernate mode, PC is saving its current state to a disk rather than that of Memory. Hibernate mode requires a boot-up, but draws a shutdown amount of power, though it takes a bit longer to pick up compared to Sleep. Hibernate mode needs to retrieve files back to the Memory from a hard drive, allowing you to look back to the saved data or opened programs and documents in the current state.

When To hibernate or Sleep,
It depends, many people leave their PC running 24/7, while others don’t even consider using Sleep and hibernate modes, but also not using the shutdown mode conveniently.
- When to use Sleep mode: As the name suggests, Sleep mode comes into play when a user decides to walk away from a machine for a while to give himself a rest. For how much time the machine should stay in a sleep mode depends on battery life. If the power adapter snapped in, then the time shouldn’t bother you. The sleep state is sort of an energy-efficient compared to when you leave your laptop up and running.
- When to use Hibernate mode: This mode is way better than sleep mode in terms of power-saving. Hibernate is slower to proceed with a PC. You can use it when planning to take a nap or stepping away from your laptop for a bit longer. If time is a matter of concern, then you can drop the idea of using this mode, rather use sleep mode. With hibernate mode, you save much power, but when you shut down or hibernate your pc, you may have to wait a little longer to resume your data.
The power that is fetched through Sleep and the hibernate mode controls by the PC. Some people don’t require using hibernate mode because, for them, sleep mode works like a charm if a Pc is on charging. It’s worth noting that, a sleep mode may have a slower response than hibernate, but it just uses a few watts of power and is quick to go on with.
It’s not that you don’t need a hibernate mode at all levels. The fact is, hibernate mode can save you a bucketload of power when no charging adapter is in place. It may have a bit slow-going process, yet, it is something we can’t ignore.
