Introduction
The motherboard of a computer is its control center and can seem daunting to replace. This guide will demonstrate how to efficiently replace the motherboard for a Dell Precision 7560 laptop.
Motherboards can be damaged by rough handling, drops, water damage, or power surges.
Some possible indications of a failing motherboard are: external USB devices are no longer being read by the laptop correctly, if at all; the laptop is operating much slower than normal; the computer boots with a blank blue screen, and/or any burning smell coming from the laptop while operating.
Power off and unplug your device before beginning.
