Coming out of sleep is much faster than booting from a shut do | Computer hardware and networking

Coming out of sleep is much faster than booting from a shut down and can even feel instantaneous on faster machines.Sleep, however, requires more power on all desktops and laptops. During sleep, machines will only retain everything in memory as long as the power supply is constant. 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. 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.

Hibernate: Putting your system on Hibernate is basically like putting it on sleep, but without the continuous use of power that sleep demands. When in hibernation, your computer saves its current state to the hard drive instead of its memory, or RAM. For this reason, it takes longer to resume from a state of hibernation compared to sleep. However, this mode uses less power than sleep too.

Hibernation is a mid-way between shutting down your machine and putting it to sleep. I would call it shutting down, but while saving data of whatever is going on. Because hibernating uses a negligible amount of power, it is also impervious to power cuts as the data is saved to the hard disk.

wever, if your computer is going to be resting for shorter periods, you may want to look at the two other options.

Hibernate: Try hibernating your computer if you’re going to turn it off at night only to start it again in the morning. This will save you the time of booting up and will barely consume more power. However, hibernation is known to have issues with certain programs so make sure you try this on a weekend first if you haven’t before.

Sleep: You can put your desktop or laptop to sleep for short breaks, or longer ones when you know you may have to resume work quickly at short notice. Machines on sleep resume quickly, making this the ideal resting mode during lunch break at the office.

However, you may instead want to hibernate or shut down if you want to save power on your laptop or, for desktops, especially if you’re suffering from sudden power cuts.
