Hi Chezzum,
Thank you for posting here in the community. I'm sorry that your Nest Hub won't turn on. This could be frustrating, especially if the Nest Hub screen went black and you tried to reboot but it didn't work. Help's here.
I just want to make sure. Are you using the original power supply and adapter that came with your device?
Please try these steps, depending on the model of display you have:
Nest Hub (1st generation)
- Plug in the device to a different power source, then reboot the device (unplug the power cord, leave it unplugged for 1 minute, then plug the power cord back in).
- If the issue persists, put the device in recovery mode with these steps:
- Unplug the power cord.
- Hold down the volume buttons and plug in the power cord at the same time.
- Wait for the device to turn on.
- Release the volume buttons.
- Once the device is in recovery mode, on the back of the device, press and hold both volume buttons together for about 10 seconds.
Nest Hub (2nd generation)
- Try plugging the device into a different power source.
- Attempt a factory data reset. On the back of the device, press and hold both volume buttons together for 10 seconds.
Nest Hub Max
- Try plugging the device into a different power source.
- Attempt a factory data reset. On the back of the device, press and hold both volume buttons together for about 10 seconds.
- If the issue persists, put the device in recovery mode with these steps:
- Unplug the power cord.
- Hold down the volume buttons and plug in the power cord at the same time.
- Wait for the device to turn on.
- Release the volume buttons.
- Once the device is in recovery mode, press and hold both volume buttons for 10 seconds.
Let me know if you need more assistance.
Regards,
Byron
