Preparing Chromebooks for Storage (Long-Term)

Modified on Tue, 28 Nov 2023 at 02:22 PM

Chromebook batteries will slowly discharge even if they are turned off. If the battery is allowed to discharge below 1%, it can enter permanent failure mode. To avoid this, Dell recommends the following procedures anytime Chromebooks are being stored long-term (e.g., over the summer). 

The procedure works for the following models: 

  • CB 3110s (non-touch)

  • CB 3100s (touch and non-touch)

  • CB 3180s

  • CB 3189s

Placing Chromebooks in Long-Term Storage (LTS) mode 

  1. Update the Chromebook to the latest version of the ChromeOS 
  2. Charge the Chromebook until the battery is at least 80% full.
  3. Connect the Chromebook to an AC Charger and turn it on.
  4. With the AC Adaptor connected, hold Refresh + Power simultaneously for at least three (3) seconds. 
  5. While still holding the Refresh + Power keys, unplug the AC Adaptor from the Chromebook
  6. Release the Refresh + Power keys
  7. Confirm the battery is disconnected by pressing the power button to see if it turns on (it should not)
  8. Store the Chromebook in a cool, dry place

Note: The Chromebook should not turn on despite repeatedly pressing the power button or by opening/closing the lid. If it does, repeat steps 1-6. 

Getting Chromebooks out of LTS mode

  1. Connect the Chromebook to an AC Charger

  2. Power on the Chromebook while the AC Charger is still connected

  3. Charge the Chromebook until it is fully changed

  4. You're done!
