Hello JazzyAunt,

Thanks for reaching out here in the Community. To know more about this issue, I'd like to confirm, what is the light status of your Nest Thermostat when you charge it and if it's not charging? Try using a different USB cable to charge it and try plugging it to a different wall outlet. Make sure that the USB cable is working. Let us know your update here.

Regards,
Emerson

Emerson,

It has a blinking green light, it has been charging for 2 days and it has a blinking green light.

Hi folks,

@JazzyAunt, chiming in — thanks for the update. Blinking green light means that the Nest Thermostat is on the software update phase software, boot up phase, restart phase, or the thermostat is connected to a charger. Usually, when the thermostat flashes a green light, it only lasts a minute or two. 

Let's give these troubleshooting steps a whirl:

1. Remove and reconnect the display.
2. If the issue persists, press and hold down your thermostat ring for 10 seconds to restart it.
3. If the issue persists, verify that the thermostat mounts (can get detected by a computer if it’s connected via a micro-USB cable).
4. If the Nest drive doesn’t mount, restart the thermostat and the computer.
5. If the Nest drive still doesn’t mount, connect another USB device to the computer via the cable to check if it detects and/or installs the USB device.
   1. If the computer doesn’t detect the USB device, use a different USB cable, USB port, or computer.
   2. If the computer detects the USB device, manually eject the USB device, and then replug the display into the computer.

Let me know how it goes.

I appreciate the help, Emerson.

Best,

Jenelyn
