    ● Using a non-Dell or incompatible battery may increase the risk of fire or explosion. Replace the battery only with a compatible battery purchased from Dell that is designed to work with your Dell computer. Do not use a battery from other computers with your computer.

  • Page 100: Chromebook Storage

    Failure to follow these steps could cause your batteries to reach a critically low charge when the Chromebook is stored for long periods of time, and can result in permanent failure of the battery. Dell provides a standard 1-year warranty on batteries.

  • Page 101: Preparing The Chromebook For Long-Term Storage

    Preparing the Chromebook for long-term storage Prerequisites Update your Chromebook to the latest version of the ChromeOS and charge so that the battery is at least 80% full. This ensures that even when the battery discharges while unplugged over the summer, power is not fully depleted.
