はじめに
If any Dell Precision M3800 keys are no longer working, use this guide to replace the keyboard.
Before using this guide, check for foreign objects under the keys that can cause underperformance. You may be able to fix this issue by dislodging said objects with an ESD-safe brush or small dust blower, instead of replacing the equipment.
Before beginning, be sure to power down the laptop, and unplug from the external power source(s).
Note Before Beginning: You can perform the removal of the fans, RAM, and USB Ports in any order. You might notice some of the later steps have photos that still include parts that were removed previously, this is because you can remove these parts in any order.
