I would call it shutting down, but while saving data of whatever is going on. Hibernation is a mid-way between shutting down your machine and putting it to sleep. However, this mode uses less power than sleep too. For this reason, it takes longer to resume from a state of hibernation compared to sleep. When in hibernation, your computer saves its current state to the hard drive instead of its memory, or RAM. Hibernate: Putting your system on Hibernate is basically like putting it on sleep, but without the continuous use of power that sleep demands. Hence, the sleep option also means your machine is vulnerable to power cuts as a continuous power supply is required to keep things in memory. For instance, if your desktop is on sleep and you suddenly lose power, you will be booting from a shutdown instead of waking the machine from sleep. During sleep, machines will only retain everything in memory as long as the power supply is constant. Sleep, however, requires more power on all desktops and laptops. Coming out of sleep is much faster than booting from a shut down and can even feel instantaneous on faster machines.Īlso Read | Netflix: How to change language on phones, browsers and Smart TVs The machine will also come back to life very quickly from sleep.

Also, shut down is impervious to a sudden loss in power like a power cut. Regardless, coming out of a shut down will still be slower than the two other options we will discuss today. This can be fast or slow depending upon your machine’s specifications, and you may or may not be bothered by your boot up times. This is because the whole computer is shut down along with the operating system, your whole system needs to boot up from scratch when you turn it on again. However, while a shut down is the best option if you want to save power, it is the least efficient if you’re going to turn your computer back on in a short span of time.
