Toshiba Chromebook 2 Motherboard Replacement

はじめに

Motherboards can be damaged by significant trauma or a power surge, resulting in a computer that will not turn on or respond. Motherboards can also be upgraded to enhance the performance of your computer. Replacing a motherboard is often seen as a last resort as all components of the computer attach to the motherboard, and therefore must be disconnected to replace. iFixit provides a helpful page for Troubleshooting a Computer Motherboard.
