Storing Chrome device for long term — best
practices
Prior to long term (Summer) storage:
1. Update to the latest version of the Chrome OS and charge your Chrome device so that the battery is at least 80% full.
a. This ensures that even when the battery discharges while unplugged over the summer, it will not fully run out of power.
2. Connect the device to a charger and then turn it on.
3. Hold Refresh and Power
4. While holding these keys, remove the power cable from the device and then release the keys. The device should shut down and
remain off.
5. Attempt to power the unit on, by pressing the power button. If the unit does not power on, you have completed the steps and can
safely store the system. If the unit powers on, you should repeat steps 2 to 4.
Upon redeploying:
1. Connect the Chrome device to a charger and a power source, which will get them out of the battery disconnect state. Power up your
device.
2. Connect your Chrome device to WiFi and update them to the latest Chrome OS release.
a. This can take time, as multiple Chrome OS versions may have been released since the last time the device was updated.
