Whenever a family member tells me about something that's gone haywire on any of their devices, whether it's an iPhone, iPad, modem, Echo, coffee maker… the first thing I ask is, "Have you tried turning it off and on again?" It's a tried and true method for troubleshooting a lot of glitches in a device's system. It's also one of the first things a tech support person will ask you when you call for help.
Every device is different, but most of them follow a similar set of steps for power cycling. Here's how to power cycle all of Apple's products, as well as some of the more common devices that you might find in an average tech-savvy home.

How to power cycle an iPhone and iPad
If you're experiencing lag, a slowdown of actions, glitches in any of the built-in apps on your iPhone or iPad, or pretty much any problem, the first thing you should do is turn it off and on again.
On iPhone 8 Plus and older:
- Press and hold down the On/Off button on the right side of your iPhone 6 or newer (it's on the top of all other iPhones, iPads, and iPods) for three seconds.
- Swipe the Slide to Power Off slider to the right.
On iPhone X:
- Quickly press and release the Volume Up button.
- Quickly press and release the Volume Down button.
- Press the Side button (sleep/wake, on/off).
Once off, give it just a few seconds to rest, then turn it back on again. You can turn on your iPhone by pressing the Sleep/Wake, On/Off button, which is on the right side on iPhone 6 or newer or on top for all other iPhones, iPods, and iPads, for three seconds.
If your iPhone doesn't respond to the actions to power it off, you might need to reboot the system.

How to power cycle a Mac
Though a problem on your Mac may go much deeper than simply turning it off and on again, it's still going to be one of the first thing a support technician will do or ask you to do when you take it in for repairs. Do yourself a favor and power cycle your Mac before calling a support technician, just in case that fixes the problem you're having.
- Click on the Apple Menu button in the upper left corner of your Mac's screen.
- Click on Restart from the drop-down menu.
- Click on Restart when asked to confirm if you want to restart your Mac.
Note: You can select to reopen the currently open windows when you log back in if you want to continue right where you left off.
After you click on Restart, your Mac will begin the shutdown process. If any apps are running, your Mac will ask you to manually shut them down before continuing.
Once your Mac has completely shut down, you can press the Power button for three seconds to turn it back on.

How to power cycle a modem or router
If you're internet suddenly poops out on you - if your streaming media service freezes up or if you can't log into your favorite social media sites, there might be an issue with your service provider. But, there might be an issue with your modem or router. Before you call your internet provider to complain about an outage, try power cycling the modem or router.
Every modem and router is different. There's no easy way to explain how, specifically, to power cycle every one. Luckily, most of them have the same basic functions and will use the same steps to shut down and restart.
- Unplug the power cord from the modem.
- Wait 30 seconds.
- Plug the power cord back into the modem.
- Wait for the WI-Fi or Ethernet lights to turn solid green.
- Confirm that your modem works by connecting to the internet using a device on your local wifi or Ethernet.

- Unplug the power cord from the Echo device.
- Wait 30 seconds.
- Plug the power cord back into the Echo device.
- Wait for the light ring to turn blue.

- Using a paperclip or other small tool, press and hold the Reset button at the bottom of the Echo device.
- Wait for the light ring to turn orange and then blue.

How to power cycle a smart home hub
If your smart home hub is not discovering new bulbs or other gadgets, you can refresh the wifi connection and restart the hub to try to clear the way for a proper connection.
Every smart home hub is different. There is no easy way to explain how, specifically, to power cycle every one. Luckily, most of them have the same basic functions and will use the same steps to shut down and restart.
- Unplug the Ethernet cable from the smart home hub.
- Wait 10 seconds.
- Plug the Ethernet cable back in.
- Follow the manufacturer steps to connect your smart device.
If that doesn't work:
- Press the Reset button on your smart home hub (usually on the back or bottom of the hub).
- Wait up to 10 minutes for the indicator light to indicate that it is back online (usually solid green, but may be solid blue).
- Follow the steps above to unplug and reconnect the Ethernet cable again.
- Follow the manufacturer steps to connect your smart device.
If that still doesn't work, follow the steps to power cycle your modem or router and then re-setup your smart home hub per the manufacturer instructions.
