Lenovo ThinkPad T470s Motherboard Replacement

简介

This guide will walk you through the steps for replacing the motherboard in your Lenovo ThinkPad T470s.

The motherboard works as a nervous system for the computer; it allows components, such as the Wi-Fi card and RAM, to "communicate," running the operating system and your computer.

Motherboards can be damaged by rough handling, drops, water damage, or power surges.

Some possible indications of a failing motherboard are: your external USB devices are no longer being read by the laptop correctly, if at all; the laptop is operating much slower than usual; the computer boots with the blue screen of death, and/or any burning smell coming from the laptop while operating.

Power off and unplug your device before beginning.
