Dell Precision M3800 Touch Pad Replacement

はじめに

If the Dell Precision M3800 touchpad is unresponsive or not working, use this guide to replace the touchpad.

The touchpad works as the “mouse” for the laptop, and an unresponsive touchpad would stop the user from using the laptop, unless the user uses an external mouse.

Before beginning, be sure to power down the laptop, and unplug from the external power source(s).
