How to restart your mac

You can use keyboard shortcuts to put your Mac to sleep, shut down or even restart. These shortcuts work on all versions of macOS.

Save a Click and Allow Keyboard Shortcuts to Shut Down, Restart or Put Your Mac to Sleep

Keyboard shortcuts can be handy in a lot of situations. Though powering off or restarting a computer is a process that takes a couple of clicks, but you can speed that up too using keyboard shortcuts. Who knew!

Interestingly, there are keyboard shortcuts available if you want to shut down, sleep or restart your Mac. Though they are not super obvious to learn, but once you get the hang of it, you will be a pro at powering off or putting your Mac to sleep whenever needed, all without having to move your mouse around.

We will break this tutorial down into several headings so you can easily learn what you are looking for. There is even a shortcut for turning off the display, should you require that for whatever reason.

Shut Down Mac Using Keyboard Shortcut

To shut down your Mac, press the following key combination exactly as shown:

Command + Option + Control + Eject / Power

Keyboard Shortcut for Sleep

To put your Mac to sleep, press:

Command + Option + Eject / Power

Turn Off Display

You can quickly turn off your Mac’s display, internal and external both, by pressing:

Shift + Control + Eject / Power

Restart Mac Using Keyboard Shortcut

Last but not the least, you can restart your Mac at any given time by pressing the following key combination:

Control + Command + Eject / Power

Like I mentioned before, these keyboard shortcuts are not so obvious. They do take time to learn. Just print them out and slap it onto a wall until they are hardwired into memory.

For me, the most handy shortcut is the one for turning off the display. Without having to reveal your work to anyone and putting your Mac to sleep, use it to keep things rolling in the background. This is particularly great for times when you are downloading something and you do not want to put your Mac to sleep. Just turning the display off works.

Learn what to do if your computer restarts or shuts down unexpectedly, or you get a message that your computer restarted or shut down because of a problem.

About unexpected restarts

Rarely, your Mac might experience a software or hardware issue that requires it to restart. When it starts up again, you might see a message that your computer was restarted because of a problem.

How to restart your mac

Unexpected restarts are usually caused by software installed on your Mac, or by devices connected to your Mac. If the issue causes your Mac to restart every time it attempts to start up, your Mac might eventually shut down. Use the steps below to check the software and hardware on your Mac.

Check your software

If the issue is caused by software on your Mac, one of these steps might help:

    .
  • If your Mac suspects that a particular app caused the restart, it might ask whether you would like to move the app to the Trash. Click Move to Trash, then contact the software developer to see if a software update is available.
  • Use safe mode to try to isolate the cause of the issue. . If the issue continues after reinstalling macOS, check your hardware.

Check your hardware

Learn how to check your connected devices and other hardware.

Check peripheral devices first

If you don’t have any devices attached to your Mac, skip to the next section.

  1. Shut down your Mac.
  2. Disconnect all peripheral devices, such as hard drives or printers. If you have a desktop Mac, make sure that only a display, keyboard, and mouse or trackpad are connected.
  3. Turn on your Mac.
  4. Use your Mac for the amount of time that it would usually take for an unexpected restart to occur.
  5. If an unexpected restart occurs, follow the steps to check the internal RAM and third-party hardware.
  6. If an unexpected restart doesn’t occur, turn off the Mac and connect one peripheral device at a time until an unexpected restart occurs.

Check RAM and third-party hardware

Certain models of Mac computers have removable memory (RAM). If you recently installed memory or a hard disk (or SSD), make sure that it’s compatible and installed correctly. If possible, remove it and test with the original memory or disk.

  • If you continue to experience unexpected restarts, contact Apple Support.
  • If your Mac is frequently restarting unexpectedly, it’s important to determine the exact steps that lead up to the issue. The next time that your Mac restarts unexpectedly, record the date and time it occurs. These questions might help you diagnose the problem:
    • Was the computer starting up, shutting down, or performing a particular task when the unexpected restart happened?
    • Is the computer restart random, or does it happen every time you do a certain task?
    • Does the restart happen when a specific external device is connected to your Mac or to a specific port?

    Force restarting a MacBook, MacBook Air, or MacBook Pro is generally considered a last resort, but if the worst happens and your machine freezes up, it’s the quickest way of getting things running again.

    alt=”macbook, macbook air, macbook pro” width=”800″ height=”234″ />
    Before taking this extreme option though, it’s worth making sure that you’ve exhausted all potential software solutions.

    • If it’s just an application that’s frozen rather than the operating system, hold down the Option (⌥) key then right-click the offending app’s icon in the Dock and select Force Quit.
    • If the OS is frozen but the mouse cursor still responds, click the Apple () symbol in the upper left corner of the screen and select Restart. Otherwise, try holding down the Control (Ctrl) key and pressing the power button. If the system shutdown dialog appears, select Restart from the available options.

    On MacBooks with physical function (F1–F12) keys, the power button is the key in the upper right corner of the keyboard (if it’s an older Mac with an optical drive, this is also the Eject button).

    How to Force Restart Your Mac

    • Press and hold down the Command (⌘) and Control (Ctrl) keys along with the power button (or the ‌Touch ID‌ / Eject button, depending on the Mac model) until the screen goes blank and the machine restarts.

    If your MacBook repeatedly freezes and you’re unsure what’s causing the problem, consider restarting your Mac in Apple Diagnostics mode to check if it’s a hardware issue.

    If your Mac is acting a bit unresponsive, running slowly, programs aren’t running properly, or is displaying any other sort of abnormal behavior, sometimes all it needs is a reboot. Here are a few different ways to do that.

    Restart Your Mac Using the Apple Menu

    The quickest (and easiest) way to restart your Mac is by using the power options from the Apple menu on the desktop. First, select the “Apple” icon at the top-left corner of the computer’s interface.

    How to restart your mac

    In the menu that appears, select the “Restart” button.

    How to restart your mac

    Your Mac will now restart. Give your computer a minute to come back up and most of your lag or small issues should (hopefully) be fixed.

    Restart Your Mac from Terminal

    If you’re a bit more technical, you can restart your Apple computer using the Terminal. Go ahead and open the Terminal. You can do this by pressing the Command + Space keys simultaneously to open the Spotlight Search, typing “Terminal” in the search bar, and then selecting the “Terminal” app from the results.

    How to restart your mac

    Now you’re ready to reboot your Mac. Keep in mind that you’ll need to use the “sudo” command here. Otherwise, you’ll be greeted by the error message shown below.

    How to restart your mac

    The sudo (superuser do) command gives you superuser security privileges.

    To restart your Mac, enter the following command:

    Sudo shutdown -r

    Replace

    Press Enter and then type your Mac’s password when prompted.

    How to restart your mac

    Your Mac will now restart at the specified time.

    Force Restart Your Mac

    If your cursor is frozen and your Mac won’t respond, you can do a force restart. Keep in mind that if you force a restart, you will likely lose any unsaved work in documents you’re working on.

    To force a restart, press and hold the Control + Command + Power keys simultaneously until your computer’s screen goes blank. Your Mac will reboot after several seconds.

    Alternatively, if you use an iMac or other Mac tower with a physical Power button, you can long-press the button until your display goes black.

    I’m getting more interested in using Terminal as an alternative way to address solutions on my Mac. I have seen this question entitled “Is there a better way to shutdown/restart OSX?”.

    I would therefore like to know:

    How to shut down, restart and sleep my Mac using the Terminal command exclusively ?

    4 Answers 4

    The command you are after is shutdown. This informs all users that the machine is going to be shutdown and tells all apps to close files etc.

    The command takes a parameter -h , -r or -s to shut down, restart or sleep the Mac.

    The command has to be run as root so you need to use sudo .

    e.g. to reboot the machine immediately

    e.g. to shutdown the machine in 60 minutes

    From comments there are two things to be addressed

    How shutdown works is by sending a sigterm to all processes which should then deal with that e.g. save open files etc. If they don’t exit then they will get sent a SIGKILL which forces them to die with no chance to respond. The signals are not sent via the normal key message queue so Apps have to deal with this separately to the code that gets called from quit on the menu. A good app should call common code from both.

    This other answer shows how to shutdown as if you hit the menu options. But note that apps can cancel this shutdown

    Shut down without showing a confirmation dialog:

    Shut down after showing a confirmation dialog:

    Log out without showing a confirmation dialog:

    Log out after showing a confirmation dialog:

    Go to sleep ( pmset ):

    Go to sleep (AppleScript):

    Put displays to sleep (10.9 and later):

    The four letter codes for the Apple events are listed in AERegistry.h .

    All System Events commands above send Apple events to the loginwindow process. loginwindow is sent the same Apple events as above when you log out, restart, shut down, or put the the Mac to sleep normally. See Technical Q&A QA1134: Programmatically causing restart, shutdown and/or logout.

    According to man shutdown , shutdown -h now and shutdown -r now send processes a TERM signal followed by a KILL signal.

    According to the Daemons and Services Programming Guide, when you tell loginwindow to log out, processes that support sudden termination are sent a KILL signal, and processes that don’t support sudden termination are terminated in different ways: Cocoa applications receive the applicationShouldTerminate: delegate method, foreground applications receive the kAEQuitApplication Apple event, background applications receive the kAEQuitApplication Apple event followed by a KILL signal, and daemons receive a TERM signal followed by a KILL signal after a few seconds.

    But there’s a little bit more to how we can play with these commands, and alternatives when the computer is totally not responding. Read on to find out!

    TABLE OF CONTENTS

    WINDOWS RESTART & SHUTDOWN

    The command to shut down or restart a Windows computer is “shutdown”. But over the many years, it has evolved to become more capable and complicated.

    ALL THE SHUTDOWN OPTIONS

    To get all the options, simply type shutdown or shutdown /? in the command prompt:

    BASIC SHUTDOWN PROCEDURES

    • shutdown /s Shuts down the computer.
    • shutdown /r Restarts the computer.
    • shutdown /l Log off.
    • shutdown /h Hibernate.

    Yep, that’s all to it.

    FORCE SHUTDOWN A STUBBORN PC

    If an application or process is blocking the shutdown or reset, we can use shutdown /p /f to force a shutdown… No warnings will be given, and it will act immediately.

    MAC RESTART & SHUTDOWN

    There are 3 commands to shut down a Mac – shutdown, halt, and reboot. Of course, being a Unix based system, these commands will also work on Linux… Although things might somewhat vary depending on the Linux build.

    THE SHUTDOWN SYNTAX

    Unlike Windows, the shutdown command is very cryptic… Which is even scarier for beginners. But in short, the sudo part is “run as administrator”, and it has a syntax of shutdown [OPTIONS] [TIME] [MESSAGE] .

    SHUTDOWN OPTIONS

    • shutdown -h Halt the system.
    • shutdown -r Reboot the system.
    • shutdown -s Put the system into sleep mode.
    • shutdown -k More for Mac server usage. Does not shut down, but kick everyone off the system.

    SHUTDOWN TIME

    • shutdown -h now Right now.
    • shutdown -h 12:34 An exact time.
    • shutdown -h +15 Specified minutes later.

    SHUTDOWN MESSAGE

    This is optional and will serve a warning message to all users who are logged on to the Mac before shutting down or resetting.

    HOW ABOUT HALT AND REBOOT?

    • shutdown -h is equals to calling halt
    • shutdown -r is equals to calling reboot

    But not really… It’s kind of confusing. But shutdown , halt , and reboot all belong to the same system module that deals with shutting down and rebooting.

    EXTRA BITS

    That’s it for the shutdown commands, and here are a few extra bits that may be useful to you.

    FORCE QUIT

    • Windows – Press Ctrl-Shift-Escape to fire up the task manager. Select and close the application that is not responding.
    • Mac – Press Option-Command-Escape to fire up the force quit dialog box. Select and close the application that is not responding.

    FORCE POWER OFF

    If the shutdown commands will not even work, the last straw is to call for a hard power off – Press and hold the power button for at least 4 seconds to force a power down; This is a function on the motherboard and not the operating system… If it still does not power down, it might be a hardware problem instead of software.

    I’ve looked around and bit for an answer to this question but I don’t seem to find it (which is weird).

    My question is, is there any simple way to restart the BASH session from within the terminal on Mac. I just want the same behaviour as if I closed the terminal application and started it again (all variables reset, .bash_profile sourced etc).

    I know how to source .bash_profile , but that’s not what I want. One of the reasons I want to do this is because a plugin for my BASH prompt has code that prevents colors from being loaded multiple times. Therefore, sourcing .bash_profile doesn’t reload the color variables and I have to restart the terminal application to get changes in effect.

    exec bash should replace the current shell process with (a new instance of) bash.

    EDIT: Seems from answers below that Catalina replaces bash with zsh. You can run exec zsh in that case, or alternatively exec “$SHELL” which should always use your default shell.

    tl;dr use exec $SHELL if you want the start the same shell you’re in. The accepted answer will only work for you if you’re using bash.

    The accepted answer is great for a shell that’s using bash, which is also what the OP asked, however, I’m using Terminal on macOS with a non-default shell (zsh) and running the command exec bash obviously doesn’t have the desired effect: it launches bash instead of my default shell.

    So the environment-agnostic command would be exec $SHELL which utilizes the environment variable $SHELL that stores the default shell for the user.

    Also, note that Apple replaced bash with zsh in macOS Catalina so to have the effect the OP is looking for running either exec zsh or exec $SHELL is the way to go after updating to macOS 10.15.

    Me and @Boardiesboi had the same issue, restarted our devices, then battery percentage became stuck, wouldn’t go down, only way to get it to show correctly, was by restarting the phone every time, only restoring the device fixed the issue. 🤦‍♂️

    DON’T. restart your phone.

    I did a hard reset/reboot and the battery dropped from 97% to 92%.
    Used it for maybe 15 mins or so since then but the battery was then stuck at 92%
    I then plugged the phone into the Mac and checked Coconut Battery and the charge is 88%
    Rebooted the phone again and battery showing as 88%

    Tried to reset all settings and that didn’t help.

    I’ll have to restore.

    Latest screenshot of the battery settings show this. Battery usage under last 24 hours is stuck at 0%

    Surely it’s a software bug and should affect all users?

    This could be on limited small chipset supplies, maybe orders are being rushed out to other product suppliers’ manufacturing plants and thus 2x quality control is being missed before some 10 or every 1000 units are tested and shipped for final delivery.

    Simple solution:
    kill the MagSafe overpriced (even today’s price drop) junk. Let the accessory partners make such units, better value for end users, least expense for Apple. chips can be used in other products.

    The iPhone 12 and iPhone 12 Pro may be high performance, but that won’t stop the occasional need to force restart your mobile device. Here’s the steps you need to reboot your iPhone 12 if a graceful shutdown isn’t possible.

    While it is entirely possible for some iPhone users to never need to turn off or restart their device at all, the vast majority of users will at some point need to do so. Maybe an app hung in such a way that iOS can’t handle, or the iPhone stops responding to touches and individual button presses.

    In such situations, the best course of action is to restart your iPhone, but even that may not be immediately possible, such as if the screen isn’t responding to touch input, preventing you from performing the final swipe to power it off. Even in this scenario, you can still forcefully restart the device.

    This guide will take you through the usual way of turning off your iPhone, and then to do the forced restart. It is usually advisable to go for the first method, but the second is also useful as it is a generally quicker process to reboot, and far more likely to work.

    These methods cover practically all models that use Face ID as their biometric authentication system, from the iPhone X to modern models including the iPhone 12 and iPhone 12 Pro. It can even be used on iPad models that use Face ID, such as the current-generation iPad Pro, with the force restart method even able to be used on the iPhone 8 and iPhone 8 Plus.

    Most earlier models have different techniques to force a restart, typically relying on a press of the Home button. Its removal forced Apple to come up with a newer procedure for the iPhone X, which it has continued to use ever since.

    How to turn the iPhone 12 off then on again

    • Hold down both the volume up and side buttons at the same time for a few seconds.
    • Press the on-screen power symbol at the top of the screen and slide it to the right.
    • To turn it back on, hold the side button until the Apple logo appears.

    This method performs a graceful shutdown of the iPhone, followed by the standard turn-on procedure. This is the method you should be trying to accomplish first.

    How to restart your mac

    In the event that you cannot use the iPhone’s touchscreen, step two of that list will not be possible to complete. This is why there is a method to forcefully restart the device.

    How to force restart the iPhone 12 and iPhone 12 Pro

    • Press and very quickly release the volume up button, followed by the volume down button.
    • Press and hold down the side button.
    • When the Apple logo appears, release the side button.

    While this method will attempt to restart your iPhone, it may not necessarily fix the problem. Apple’s support pages offer further advice if the iPhone won’t turn back on, including how to restore the device in more serious cases.

    How to restart your mac

    As a word of warning, make sure to pay attention when you are restarting your iPhone, and follow all instructions properly. This is specifically the case if you confuse the two sets of instructions and end up holding down the volume up and side buttons for a prolonged period of time.

    Doing so will start a five-second countdown for the Emergency SOS function, where it will count down from five and vibrate for each number, as the Emergency SOS slider fills up. On reaching 0 while still holding both buttons down, the iPhone will consider the bar full and dial the emergency services, which may prompt the police or an ambulance visit to your location.

    Just remember to pay attention and to release the buttons if the vibration and countdown starts.

    How to restart your mac

    With the release of the iPhone 8 and iPhone X, Apple made some changes to the methods used to force restart its flagship device. These changes come just a year after Apple made similar changes to the iPhone 7 — the first iOS device to don a solid state Home button.

    These changes not only affect force restarts, but also alter the process for entering recovery-mode and DFU mode. Have a look at our brief video walkthrough inside for a look at the changes in action.

    As we noted in our hands-on video walkthrough of the second iOS 11.1 beta release, pressing and the holding Sleep/Wake button (now officially renamed the Side button) + either volume buttons invokes the emergency dialing (SOS) functionality on the iPhone 8.

    This behavior is present on all iPhone 8 and 8 Plus models running iOS 11. With this change in functionality in mind, a new method for force restarts, recovery-mode, and DFU mode needed to be implemented, and Apple has done just that.

    How to force restart iPhone 8

    To force restart (hard reset) the iPhone 8, press and release the Volume Up button, press and release the Volume Down button, and press and hold the Side button until your device reboots, then release. All three button presses should be done in relatively quick succession. After holding the Side button for about ten seconds, the iPhone will force restart.

    Video walkthrough

    How to get into recovery-mode on iPhone 8

    Step 1: Connect your iPhone 8 to your Mac or PC with a Lightning to USB cable.

    Step 2: Press and release the Volume Up button, press and release the Volume Down button, and press and hold the Side button until your device reboots. Continue holding the Side button, even after you see the Apple logo appear.

    Step 3: Release the Side button once you see the Connect to iTunes logo appear on the iPhone’s display.

    Step 4: Launch iTunes, and you should see a message stating that “There is a problem with the iPhone that requires it to be updated or restored.” From there, you can choose to Update or Restore your iPhone’s software.

    How to get into DFU mode on iPhone 8

    Step 1: Connect your iPhone to your Mac or PC with a Lightning to USB cable.

    Step 2: Press and release the Volume Up button, press and release the Volume Down button, and press and hold the Side button for 10 seconds until the screen turns black.

    Step 3: While still holding the Side button, press and hold the Volume Down button for 5 seconds, and then release the Side button while continuing to hold the Volume Down button for another 10 seconds. The screen should remain black.

    Step 4: Launch iTunes, and you should see a message stating that “iTunes has detected an iPhone in recovery mode. You must restore this iPhone before it can be used with iTunes.”

    How to restart your mac

    How to exit recovery-mode or DFU mode on iPhone 8

    As long as there are no problems with your iPhone, exiting out of recovery-mode or DFU mode is simple.

    To exit out of recovery-mode, press and hold the Side button until the Connect to iTunes logo disappears. To exit out of DFU mode, press and release the Volume Up button, press and release the Volume Down button, and press and hold the Side button until you see the Apple logo appear on screen (You can also use this for exiting recovery-mode if you just prefer to remember a single method).

    How to restart your mac

    The process for managing recovery and DFU mode has gotten slightly more complicated with the iPhone 8, but it’s still relatively easy to do. Just follow the instructions demonstrated in our video walkthrough, and you’ll be a master in no time.

    How to restart your mac

    Restarting your computer is a common task. Whether for troubleshooting or software and hardware installation, most computers get restarted on a fairly regular basis. And those that don’t might start showing problems until they do get restarted. What happens when you restart your computer? It’s actually a fairly simple process involving some pretty basic commands.

    What happens when you reboot?

    How to restart your mac

    In the abstract, a reboot is indicated by a power state flag set by your computer at the end of the shutdown process. This flag tells the motherboard to reset the attached components using the correct reset commands, then follow the normal startup (AKA “bootstrap”) process.

    This reset command is nothing more than a certain value at a certain register address which the motherboard checks before moving to its “off” state. If the reboot flag is present, the computer starts the boot process as soon as the shutdown process is finished. If the flag isn’t present, the computer moves into the “soft off” state, waiting for you to come back and press the power button again.

    The reboot process is only slightly different from the shutdown process. The computer “knows” to reboot thanks to the ACPI reset command, but that’s only set after the computer has completed the shutdown process. All components get reset as part of the shutdown process, so the only difference between shutdown and reboot is that the computer restarts immediately.

    The shutdown process is pretty simple itself. When you select “shutdown” from the OS menu, the computer quits all apps, does a little housekeeping, unmounts the filesystem and turns off peripheral devices.

    What are power states?

    How to restart your mac

    Much of your computer’s shutdown and restart processes are controlled by ACPI (advanced configuration and power interface) power states. Power states come in a couple flavors and are controlled by the motherboard. These power states comes fro m ACPI, or Advanced Configuration and Power Interface, which controls power management in your PC. There are a couple important power states that help us understand how the computer operates.

    • G0: Power on and working; your computer’s operational status
    • G1: Sleeping
      • S1: RAM and CPU power stays on, but the CPU isn’t processing instructions. Peripheral devices are powered off.
      • S2: CPU is powered off, but RAM power is maintained, preserving memory contents
      • S3: Everything except RAM and peripherals that can wake the computer, like the keyboard, is powered off. This is your computer’s “sleep” state, which is triggered from the start menu in Windows.
      • S4: RAM contents are written to disk and everything powers off. This is the “hibernate” mode. The only difference between this and G2 is the resume process: you won’t need to boot your PC to return from this power state.

      Why does rebooting fix so many problems?

      Rebooting is a key troubleshooting step because it fixes a huge variety of problems. But how?

      During the reboot process, all of the computer’s logic is reset. This means that the CPU, memory, controllers and peripherals all receive their reset commands and return to their boot-up states. By wiping away anything that was happening previously, this reset can often fix problems by resetting things to their “new” state. Of course, this doesn’t mean the problem won’t reoccur. But this fresh start often removes the offending gremlin, at least temporarily.

      The steps you need to take to force restart your iPhone 11, iPhone 11 Pro or iPhone 11 Pro Max are different if you’re used to an iPhone with a Home button. Here’s how to do it.

      You could go through your entire use of an iPhone without ever having to restart it, but that’s unlikely. At some point you’re going to find that it’s going wrong and you need to power it down and start again. However, the way that you do this has changed over the years, and even now there are different ways.

      This works with the new iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max. However, if you have any iPhone X-style model — so any iPhone since the Home button was removed — you can use the same technique. You could shut down by:

      • Pressing and holding both the volume up and the Sleep/Wake button
      • Swiping to chose Slide to Power Off when prompted

      Having done that, you could then start the iPhone back up again by pressing and holding the Sleep/Wake button until you see the Apple logo.

      This is Apple’s recommended method, and actually just about the only one it even describes. There is a brief line in the official support documents about how you can shut down an iPhone by going to Settings, General, and choosing Shut Down.

      However, in our experience that can be surprisingly slow. Especially if we’re pressing the button through the plastic of a protective case, it can feel like it takes an extremely long time before the Apple logo appears.

      How to restart your mac

      Whether that’s really measurably longer or just feels like it, though, there is a faster way — and it’s one more guaranteed to work.

      If your iPhone is having serious problems, you may not even be able to make the Slide to Power Off swipe at all.

      You will always, though, be able to force an immediate restart. Briefly, what you’re going to end up doing is pressing and holding both the volume up and the Sleep/Wake buttons again. However, you’re first going to effectively tell the iPhone that you want to restart instead of shut down.

      • Press the volume up button once
      • Press the volume down button once
      • Press and hold the Sleep/Wake button
      • Keep holding even when you see Slide to Power Off
      • Keep holding until you see the Apple logo

      Do this carefully.

      If you skip the pressing of the volume up and down buttons, and instead just, for instance, hold volume up and Sleep/Wake, you get a version of the shutdown page. Rather than the regular one, it has that same Slide to Power Down option, but also an Emergency SOS button.

      And that button has a countdown that is immediately running. Hold those buttons for more than a few seconds, and your iPhone will dial the emergency services. We know your iPhone was in a bad way, but you don’t want paramedics at your door.

      Follow these instructions carefully, though, and your iPhone will spring back to life.

      Shutting down and restarting are two different operations on Windows. Do you know the main differences between them? Which one should you choose when you finished a Windows 10 session? Microsoft offers multiple ways to close or reboot a Windows 10 computer. What are they? MiniTool Solution will answer these questions for you on this page.

      Shut Down or Restart Windows 10

      You may need to shut down your computer when you don’t need it. However, if you’re doing an update or performing some system change on Windows 10, the system will ask you to restart the PC to finish the tasks. Here comes the question – how can you restart Windows 10. Should you just shut down or restart Windows 10? Now, let’s dive into these issues.

      Shutdown vs Restart vs Reboot

      Restart vs Shutdown

      In old versions of Windows (before Windows 8), restart and shutdown basically do the same thing. However, things are changed in the newer Windows 8 and Windows 10 systems due to the adding of the new feature called Fast Startup.

      • Windows 10 Restart refers to the process of closing processes, powering off computer, and powering it on again.
      • Shut down refers to the process of closing programs & files and removing power from the main computer components. However, the Windows kernel will be kept (won’t be shut down) for the next fast startup.

      That is to say, Windows will not fully shut down after you clicked “Shut Down”. That’s why you need to restart once (or more) when installing updates/software, changing settings, or solving computer problems.

      Restart vs Reboot

      Is reboot the same as restart?

      For many people, reboot and restart mean the same thing. Reboot also refers to shutting off the device temporarily, removing the power, and then turning it back on. However, there are still slight differences between them.

      • When you select Restart from the computer, all the running applications will be closed and the operating system will be shut down to the point where Windows can reload.
      • Reboot refers to pressing the button to force restart the operating system. The power supply will be discontinued for 3 seconds and the motherboard will have to run its initial boot loading process.
