Introduction

The motherboard is extremely important to the overall function of your Asus Chromebook C523N. It is a printed circuit board that allows for the overall communication between many of the components, including the CPU, RAM, and many other hardwares.

Usually, the only other solution to an unresponsive motherboard is to buy an entirely new laptop. Without the hub of your laptop, most functions are nearly impossible.

Hi!

I assembled the motherboard but it isn't working. There is no power light. How to validate that the motherboard is functioning?

If I just connect power stream to its USBC power port the LED should be lighting?

mmm -

I was following this guide and I found there were actually four screws holding the MB down. The red/blue/white/black speaker cable must also be disconnected to get the board out entirely.
