One Education Infinity CMOS Battery Replacement

Introduction

This guide describes the process of removing and replacing the CMOS battery in the One Education Infinity.

The CMOS battery can assist with software startup and keeps the internal clock running while the device is turned off. If your computer has difficulty during startup but otherwise functions normally, or if your computer forgets what time it is when you turn it on, you may have an issue with the CMOS battery. Luckily, this part is easily accessible within the bottom case of the device, so replacement will be fairly simple once the device is open. Be sure to dispose of old batteries safely.
