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.

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?
