I have a 1st gen mini that was working fine. The last few days I heard it restarting/reconnecting about once per day. Today, I thought I’d try to troubleshoot that, and the device is completely dead: no lights, no sounds, doesn’t respond to taps or voice. I’ve unplugged it, waited and replugged it in multiple times, tried the factory reset button, but the device seems to have no power. Any other suggestions? I’ve seen this issue on the forum a lot, but haven’t seen any resolution. Is it the device, or perhaps the power cable that has failed?
No, advice to reboot my router when the NEST mini doesn’t have power didn’t help. If it doesn’t have power, it can’t communicate with the router, so the router is immaterial until the unit will at least power on. I’m still looking for advice on what typically fails on these units: the power supply/cable or the unit itself.
Apologize for the delays. Chiming in to ensure everything is covered here. To confirm, do you have another Nest Mini device? If yes, let's go ahead and try to use the power cable to the other Nest Mini that won't turn on. Also, could you tell us when and where you purchased your device?
The NEST Mini was received from Google directly in Dec 2017 as a promotion with a new Google phone, so it’s 5 yrs old. I have other Google devices, but none of them have a mini USB charger like the NEST Mini.
Continuing to troubleshoot in my own, after trying a different electrical circuit in the house with the original power cable, I then tried powering the NEST device from another mini USB power cable. I got the unit to reboot and operate. I then unplugged the unit, and tried repowering it with the NEST provided cable, and it worked. It is now functioning again. My guess is that either 1) the cable is beginning to fail, causing intermittent problems, or 2) powering from a different cable reset something within the NEST Mini. And no, I never reset the router…
That's strange! But I'm glad to know that your Nest Mini is up and working now. Could it be the power outlet that has an issue? Moving forward, I'll keep the thread open for 3 more days to monitor your device. Do not hesitate to update the thread whenever you experience an issue with those days.
