Introduction

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.

    • Use a Phillips #000 screwdriver to remove the five 7 mm screws from the bottom of the laptop.

    • Lift the bottom panel up and off the laptop.

    • Slide the upper battery out of the device, away from the laptop.

    • Slide the lower battery out of the device, away from the laptop.

    My laptop says Battery 1 is at 0% and does not hold a charge and Battery 2 is at 88% and I have 4h 22min of estimates time remaining. Which battery do I need to replace? Upper or lower?

    You would think Lenovo would make this information readily available. Im in their manual right now. Not seeing anything. Extremely annoying. Will just use a trial and error method removing one and see if thats the defective one.

    Looks like battery 1 is the larger battery.

    If I remove battery 1 or 2 will there be any problem running my laptop?

    • Gently grip the motherboard and slide it to the right to remove the USB ports from the chassis.

    • You will hear an audible clicking sound.

    • Lift the motherboard up and out of the chassis.

    This seems to be missing several steps: track pad and power cable…

    Samuel Law -

    This is missing that you need to remove the keyboard as well. There are ribbon cables attached to the keyboard on the bottom on the motherboard
