Introduction

If your Dell Chromebook 3110 won’t hold a charge, drains quickly, or only works when plugged in, you likely need a battery replacement.

This step-by-step guide will show you how to safely remove and replace the battery in a Dell Chromebook 3110.

For safety:

Discharge the battery below 25% before starting the repair. This lowers the risk of fire if the battery is damaged.
If your old battery looks swollen, puffy, or smells unusual, use caution—swollen lithium-ion batteries can be hazardous. See our wiki: What to Do With a Swollen Battery.

Before beginning your Dell Chromebook 3110 battery replacement, unplug the charger and completely power off your device.
