Don’t know when to shut down, sleep, or hibernate your PC or Mac laptop? Does putting your computer to sleep damage it? Get the pros and cons for each method of powering down your laptop, then learn when to choose one option over the others. And finally, find out how an automated optimization tool can further prolong your laptop’s health.
You’re done working with your laptop, you close it and it goes into standby. But is that really the best way to give it a rest or should you maybe not use some of the other options like a cold shutdown or hibernation? In this article, we’ll go through the different options and show you what to do.
But first, the quick rundown
In situations where you just need to quickly take a break, sleep (or hybrid sleep) is your way to go.
If you don’t feel like saving all your work but you need to go away for a while, hibernation is your best option.
Every once in a while it’s wise to completely shutdown your computer to keep it fresh.
Read on for the full details.
Sleep is a very power efficient way to give your device a quick rest without completely shutting it down: Once you click on that option (or close your laptop lid), everything you’re working on and everything that's running, such as Windows or macOS and your applications, are kept in your computer's main memory (the Random Access Memory, or RAM). That RAM is then the only thing that draws batter and unnecessary built-in devices like your laptops processor, hard disk or DVD drive are powered down to save power.
Sleep mode is the best and easiest option when you’re just quickly taking a break from work and have enough battery power left (or when your laptop is connected to the power outlet). Once you open the laptop or push a button, your laptop is instantly ready with all your applications running — and you can keep on working.
Sleep still consumes just a bit of battery and while it usually takes days (or weeks!) for a device on sleep to drain a fully charged battery, it’s something to be aware of. You might wake up your laptop later to discover its lost significant amount of battery life. But don’t worry, once the battery is critical, your laptop will automatically use hibernation (see below) to completely shut down and prevent any data loss.
Also, Windows and macOS and your apps tend to slow down and become a bit unreliable after a few days without being shut down. This can be due to its memory filling up or to the amount of temporary files created, among other reasons. That's why you should still reboot your PC every so often.
Rebooting your PC won't solve all of your performance issues — for that read our handy guide to speeding up your PC.
Click on the Start button in your taskbar and then on Sleep or simply close the laptop lid. That’s it. To wake it up again, push any button on your keyboard, the power button, or open the lid.
Click on the Apple button in the top left corner and select Sleep or close your MacBook. To power it up again all you need to do is open the lid or push the power button.
Hibernating your computer turns it off completely but allows you to continue to resume all work. How so? It essentially freezes everything you’re doing and stores it safely on your hard disk in the so called “Hibernation File”. It then shuts off the entire computer so it draws zero watts from the outlet. Once you push the power button, the entire system unfreezes and you can go on working.
Hibernating your Windows PC or Mac allows you to suspend your computer without drawing electricity or battery life. You should consider putting your computer to hibernate when you’re still working on something, and not going to be around a power outlet for several days. It’s best when you have a lot of programs, open web pages, open documents, etc, going on that you will need to pick up later, and don’t feel like saving everything for later.
It takes quite a bit of a time to “hibernate” the PC and also wake it up. The simple reason for this: Everything that’s in your memory — your Windows, your programs, your open web pages, your open documents — needs to be saved to your hard disk. Depending on how many apps you’re running and how much memory you have (such as 16 GB of RAM), that means a lot of data has to be written to and read from the hard disk. So it’s not as instant as using Sleep, which is a 1-2 second deal in most cases.
Click on the Start button in your taskbar and then on Hibernate. That’s it. To wake it up again, you have to push the power button. If that option is not visible, right-click on the little battery icon in your taskbar. Then click Power Options.
On the left hand side, click on Choose what closing the lid does. Select Change settings that are currently unavailable and tick the little box next to Hibernate.
Hibernation on Mac is an interesting animal: Apple hides this option very deeply as it wants you to use the Sleep option first and foremost. It’s a very “Apple” approach to make you not think about various power options — you either shut down your Mac and or put it to sleep. We would not recommend manually enabling it (if you must, here’s how to do it).
Shutdown ends all your applications and completely powers off the laptop or desktop PC. It clears all memory, which is why I personally use it every 2-3 days to keep my system fast and responsive. It also feels like clearing up your desk a little bit.
You should consider shutting down your PC or Mac whenever you are done with any work and don’t need to pick it up later. You should especially do so if you haven’t shut down your computer in a while. As I mentioned above, I recommend doing it every 2-3 days just to clear out the kinks in the system: you’d be surprised how much better it runs with just a simple reboot. Shutting down your PC or Mac is great for getting a clean slate the next morning.
If the PC is running sluggish or if you’re experiences it’s always worth restarting.
You need to save all your work and then wait for the system to shutdown or power up.
Restarting does the same thing as shutting down: All applications are being closed and the OS (Windows/macOS) closes, but your PC or Mac powers back up again instantly. This is the option for when you feel your computer is sluggish or something isn’t working right. A good old dose of “Have you tried turning it off and on again?”.
Desktop PCs come with an option called “Hybrid Sleep”, which mixes the best of hibernation and sleep mode. It puts all information that Windows requires for a speedy startup into your RAM, which is very similar to sleep mode. But the things you are working on will be written to the hard drive just in case (remember: The RAM loses its information once the power is gone, the hard disk won’t). This is disabled on laptops or tablets because they have a battery, but if yours is dying or if you just like the concept of hybrid sleep, then you should enable it. It might take just a bit longer than sleep mode to power down and startup your device, but it’s a safe option.
Right-click on the battery icon just as you’ve done above. Select Power Options. Then click on Change plan settings next to the power plan that’s enabled. Next, go to Change advanced power settings. Go to Sleep, Allow hybrid sleep and select On.
You won’t find the new Hybrid Sleep option in your start menu, instead it replaces the Sleep option so you can just use that going forward.
Technically, when you put your PC or Mac into Sleep mode, a part of it will continue to run. In theory, this becomes part of the wear and tear of any piece of machinery that runs, but the real impact here is so low that you don’t need to worry about it. Using your laptop on a daily basis will contribute far more to component wear than any sleep mode could so you shouldn’t worry about it. Of course, shutting down and hibernating are the options with literal no wear.
