Use this guide to replace a faulty or dead motherboard in your Toshiba Satellite C875-S7304.
The motherboard is a printed circuit and is the foundation of a functioning laptop. If you notice your device suddenly stops working, it is likely due to a dead or dying motherboard.
A functional motherboard allows the laptop’s components to communicate with one another. A damaged motherboard can cause damage to other components and prevent the laptop from functioning properly. Motherboards are often the most difficult pieces of hardware to diagnose because you have to rule out every other piece of hardware connected to it. If you notice multiple faults in laptop components, slow boot times, or inabilities in recognizing connected flash drives you may want to replace your motherboard.
Disconnect the laptop from any external power source and power off your laptop completely before beginning the motherboard replacement.
