Use this guide to replace the motherboard in your Lenovo ThinkPad T470 laptop.
The motherboard, also known as a system board or mainboard, is the primary printed circuit board (PCB) in a computer that enables communication between the internal components.
Diagnosing a faulty motherboard is tricky since the symptoms are similar to other failing components. Signs of a faulty motherboard may include overheating, error codes, the blue screen of death, or failure of other ports and components.
For help diagnosing hardware failures, visit the Lenovo ThinkPad T470 maintenance manual.
Make sure to disable the internal battery, power down your device, and disconnect from any external power sources before you begin.
