Motherboards can get damaged or worn out for a variety of reasons, including physical damage, exposure to water, age, or even bad quality. This guide will show, step by step, how to remove the motherboard from a Toshiba Satellite C855D-S5109 laptop in order to replace it.
Motherboard failure will almost always result in a catastrophic failure of the laptop, so if your laptop completely refuses to turn on and you’ve already checked the battery, replacing the motherboard may restore functionality to your machine.
