Check How To Turn On And Shutdown The Raspberry Pi

If you want to turn off your Raspberry Pi, it’s not a good idea to just unplug it. The reason for this is that the Raspberry Pi may still be writing data to the SD card. In this case, simply turning it off can lead to data loss or worse, a corrupted SD card. Before shutting down, you should always shut down the Raspberry Pi safely. You can use the command line or the GUI menu on the desktop to do this. Both methods are discussed below, including options specific to the terminal command.

You need sudo user privileges to run the shutdown command. The option tells the Raspberry Pi to stop working, while the now parameter tells it to shut down immediately instead of waiting. To avoid possible data loss and SD card corruption, wait a few seconds after shutdown for the Raspberry Pi’s green LED to stop flashing before turning off the power. Once the LED has turned off, the device can be safely powered off.

How to turn on and off the Raspberry Pi

How to turn on the raspberry pi

To start your Raspberry Pi, all you have to do is plug it in. Starting with Raspberry Pi Model 4, all you need is a USB-C cable and any 5V power supply. Older Raspberry Pi models still require a 5V power supply, but use a micro USB connector.

  • First, make sure your HDMI cable is connected to your TV or monitor along with the keyboard and mouse of your choice. USB keyboards and mice work fine when first started, as do most wireless combos with their own USB receiver. Later you can connect any Bluetooth keyboard or mouse to your Raspberry Pi.
  • Plug the power adapter into a power outlet, connect the USB-C cable, and connect the other end to your Raspberry Pi.
  • A red LED will light up and you will see a rainbow screen followed by the Raspberry Pi OS desktop. From this point on, if this is your first boot into the Raspberry Pi OS, you’ll go through a few setup menus.

How to shut down a Raspberry Pi the right way

  • Since you only need to plug in the Raspberry Pi to make it work, you only need to unplug it to turn it off, right? Not absolutely not. Abruptly shutting it down before shutting down the operating system may cause your SD card to be corrupted. This danger is greater for some operating systems than others, but it is definitely a danger for Linux, the most widely used operating system on the Raspberry Pi. If you do this often enough, your Raspberry Pi won’t fully boot until you reinstall it.
  • Instead, you must perform a proper shutdown. There are several ways to do this. On the Raspberry Pi OS, you can do this by clicking the Raspberry icon in the top left corner of the screen and selecting Log Out.
  • In the next menu, you can choose to sign out, shut down, or restart. When the day is done, select Shut down. After a few minutes, your screen should go completely black and the red LED on the Pi should turn off.
  • The second way to shut down your Raspberry Pi is from the terminal. Just open a terminal, type this command and press Enter:
  • Again, you will soon see the screen turn black and the red power LED turn off. After that, you can safely remove the power cord. When you’re ready to start your Raspberry Pi again, reconnect the power cable.

Add a power button to your Raspberry Pi

  • Of course, you can also add a power button to your Raspberry Pi. There are cases that include a power button, such as the Argon40 Argon ONE M.2 Case. Additionally, CanaKit makes a power button accessory for the USB-C power cable. The downside of CanaKit’s solution is that it simply cuts power to the USB-C connector; There is no way to tell the operating system to shut down gracefully.
  • Note that your Raspberry Pi does not automatically know that it will shut down properly when you press the power button. For a power button to trigger the shutdown command, it must be connected to the GPIO header. You also need to program your Pi to trigger the shutdown command when you press the button.
  • Of course, you may not want to dive into such a project right now. In that case, you’ll probably want to stick with an external pre-built power switch.
