What If You Never Shutdown Your Computer Which Mode You Prefer: Shutdown, Hibernate And Sleep
Sleep mode uses little power. Your computer technically stays on, but all actions on your computer are stopped, any open documents and applications are put in memory. You can quickly resume normal operation within a few seconds. Use sleep mode when you are going to be away from your computer for a short time.
What If You Never Shutdown Your Computer Which Mode You Prefer: Shutdown, Hibernate And Sleep
Hibernate mode uses less power than sleep mode and is available for laptops. It takes a bit longer to resume than sleep mode does, but it will resume everything where you left off once the computer is powered back on. Use hibernate mode when you will not be using your computer for an extended time.
There are many ways to shut down your computer: You can turn the computer off completely, make the computer sleep, or let the computer enters hibernate mode. The following article introduces the operation and description of each mode in a nutshell.
If your battery nears the point of death while in sleep mode, your PC will automatically save your place onto the hard drive and will resume whenever it is plugged back into power. On a desktop, where you don't have a battery option, something called hybrid sleep takes care of the threat of losing your work when in sleep mode.
Power usage is nil when your PC is in hibernate mode, but you will experience startup times a bit longer than when coming from sleep mode. The time it takes is largely dependent on the hardware in your PC, including RAM and hard drive speeds.
A full shutdown on your machine means that everything is powered down and the internal components are no longer running. When stepping away from the computer for a short time, a full shutdown can be excessive. Alternatively, put the device to sleep, or hibernate in Windows, to put the internal components in a low power mode.
Sleep mode is typically used when you want to step away from your computer for a bit and have the system enter a lower power state. Taking a break for lunch would be such an example. When you come back to it all you have to do is press a button and your desktop and programs return to the state in which you left them. In this article, what I refer to as Sleep is automatic Sleep which is when you step away from your system for a period of time and your system goes to Sleep (unless you have disabled it of course).
Depending on your computer, it may also have a Hibernating mode. Hibernating occurs when you haven't used your laptop for a while (think an hour or two), and the computer goes a step further than sleep into hibernation. Hibernation may take a little longer for the computer to wake up, but it is safer if the power goes out since it saves the current session's data to the hard drive.
In sleep mode, the computer saves all the active sessions to RAM and goes into a power-saver mode, but it still needs to draw some power to keep the data on the RAM alive. Hibernate, on the other hand, shuts down your PC and draws no more power.
Additionally, you can set your laptop to automatically hibernate after a set amount of time. To do this, open Control Panel, and go to System and Security > Power Options; in the left pane, click on Choose when the computer sleeps. Next, click on Change advanced power settings.
Just a question to those with extensive electronic experience. Has the reliability of modern HDD improved substantially compared to HDD of 10 years ago? Are they now designed with this start/stop in mind? So although 10 years ago it may have been better to leave HDD spinning for longer, now, turning you computer on and off daily or allowing it to sleep does not significantly increase your risk of HDD failure? (there maybe an increased risk, but not significant)
Shutting down your PC versus putting it to sleep has been a long-debated subject. Some argue that turning a computer on and off too many times will damage the components, which decreases the overall lifespan. Others say that putting a computer to sleep is a waste of electricity, especially if left unused for an extended period of time.
However, for the overall health of your device, we recommend a shutdown instead of sleep. The best time to use sleep is when you have a time-consuming update to finish. Otherwise, you should go for the hibernate option.
Both sleep and hibernate turn your computer off, followed by restoring that status, but the latter leads to a shutdown. Still, when you restart your device in hibernate mode, your running applications and documents are launched instantly. In sleep mode, you just need to click the mouse or a key to restore access. Hibernate mode consumes much less power compared to sleep. Learn more about the differences between sleep, hibernation, and shutdown.
When you leave the office for the day, there's the question about what should be done with your computer. Two common options are powering it down completely and putting it into sleep mode. Both functions have their share of advantages and disadvantages and neither are particularly right or wrong for the given situation. However, there are recommendations on when best to use each function.
Sleep is a power-conserving function that allows you to quickly resume operations on your computer without having to wait the several minutes it can take to power on from a shut-down state. Sleep mode also saves all opened documents and programs, so you won't have to reopen these files again. Additionally any updates and notifications can be pushed through when your computer is in sleep mode. Sleep mode is like pressing a pause button on your computer: it stops, but is ready to resume within seconds.
While both sleep and shutdown are power-saving functions, there's still the question of what is better for your computer. According to the U.S. Department of Energy, it's recommended that you put your computer into sleep mode if you're not going to be using it for more than 20 minutes. It's also recommended that you shut down your computer if you're not going to use it for more than two hours. So at night, while you're away on vacation or away for the day are ideal times to completely shut down your computer.
According to the U.S. Department of Energy, you can save about $50 per year on each Energy Star computer that's put into sleep mode per its 20-minute recommendations, a sum that could add up to significant savings for your business. Many computer users are concerned that shutting down and rebooting their computers too many times will cause their units to die sooner than if they don't. However, the potential negative effect from shutting it down every night and rebooting it every morning likely won't lead to the end of the computer's useful life; that's usually accomplished by advances in technology.
Many computer users almost NEVER shut down their computers. There are many positive benefits to this (especially if you're a Mac user). When a Mac goes to sleep, almost every component inside the computer is turned off; what is not turned off is set in a 'low-power mode'. The contents of the RAM and Video RAM are saved, the network ports might still get a little power, and a few other subsystems stay on, but pretty much everything else is off.
parker612 has given you some good information. His 'verdict' is valid but for the six years I have used MBPs, I have always shut them down after a session (putting then to sleep only during a session, and then very rarely). I might have several sessions a day. The MBPs have never suffered any issues from this procedure. My conclusion is to do what ever suits your needs and preference.
When you're ready to shut down your PC, why not just press the power button? Why not, indeed! Except that on most computers, that button comes preprogrammed to do something else: put the machine into sleep mode.
The above script causes a system suspend, which will either sleep or hibernate depending on your current hibernate setting. To change that setting from the command line, run powercfg -h off (or on) from the command line as administrator.
I have a Mac Mini that is attached to my main TV. It stays on all the time. I have a MBP that I never do anything more than shut the lid and let macOS decide what to do (usually just sleep/hibernate).
Of course, you can if you want to - to conserve energy, or if your local power is inconsistent and you're concerned about power spikes. For the former, just set your Energy Savings so it goes to sleep which should shut down the monitor automatically, and for the latter... if you're that worried, what about when you're using it? You'd want a UPS or good surge protector for that.
Two computer modes that require distinguishing are sleep mode and hibernate, which are often used synonymously but are not in fact the same thing. Sleep mode is an energy-saving state that allows activity to resume when fully powered. Hibernate mode is also meant to be power-saving but differs from sleep mode in what is done with your data. Sleep mode stores the documents and files you are operating into the RAM, using a small amount of power in the process. Hibernate mode essentially does the same thing, but saves the information to your hard disk, which allows your computer to be turned off completely and use no energy. When you turn your it back on, your hard drive allows your work to be brought right back to where you left off. Hibernate is mainly meant for laptops and is best used in the event you are not planning to use your computer for a long period but want to keep your work up.
