Alienware 17 R5 Battery Replacement

Introduction

This guide will show you how to replace the battery in your Alienware 17 R5 (model number: ALW17C-D3748S) in the case that your battery can no longer hold a charge. In cases where an old battery will prevent the computer from being able to power on, it can be solved by allowing it to charge for a few hours or days depending on how depleted the battery is. If the battery can't hold a charge, or it is very quickly losing its charge after you have charged it, then it will need replaced. So if your computer only turns on while plugged in, and can only stay on while plugged in, then a battery replacement will likely solve your problems.
