What is what to do when your switch won't turn on?

Here's some troubleshooting information when your Nintendo Switch won't turn on:

Basic Checks:

Charge the Console: The first thing to try is charging the console. Use the official Nintendo Switch AC adapter and leave it plugged in for at least 30 minutes, even if the screen remains black. Sometimes the battery is completely depleted. Try different outlets and make sure the adapter is firmly connected to both the console and the wall. This could be a problem related to the battery%20health of your device.
Check the Power Button: Make sure you are pressing and holding the power button (located on the top of the console) for a few seconds (around 12 seconds). A quick tap might not be enough to initiate startup.

Hard Reset/Forced Restart:

Perform a Hard Reset: If charging doesn't work, try a hard reset (also called a forced restart). Press and hold the power button for 12 seconds. Then, release it and press the power button once more. If the Switch responds, it should boot up.

Troubleshooting Display Issues:

Docking Issues: If the console seems to turn on (you hear a sound or see a faint light) but there's no image on your TV, try undocking and redocking it. Make sure the dock is properly connected to the TV and powered on. Also, ensure you're using the correct HDMI input on your TV. This could be a display%20error.
Check the Screen Brightness: It's possible the screen brightness is turned all the way down. Try adjusting it (if you can get to the settings menu).

Advanced Troubleshooting (Proceed with Caution):

Check for Physical Damage: Carefully inspect the console and AC adapter for any signs of physical damage. If you see any, do not attempt to repair it yourself and contact Nintendo support.
SD Card Issues: Remove the SD card (if you have one inserted) and try turning on the Switch again. Sometimes a corrupt SD card can cause startup problems. SD card problems can lead to data%20loss.

Contact Nintendo Support:

If none of the above steps work, your Switch may have a hardware problem that requires professional repair. Contact Nintendo Support for further assistance.

Important Considerations:

Never attempt to disassemble the Nintendo Switch yourself, as this will void your warranty and could cause further damage.
Use only official Nintendo accessories (AC adapter, dock, etc.) to avoid potential compatibility issues.
