Asus Chromebook C202 Input/Output board Replacement

Introduction

If your Asus Chromebook C202 model C202SA is experiencing USB connection or charge issues due to a faulty power adapter port, then it's time to swap out the Input/Output (I/O) board. The I/O board regulates external connectors like USB connectors and the input for charging.

Make sure that such a failure is not due to loose connections, software errors, or damaged cables prior to attempting this repair. If multiple USB devices and sources of power do not work, replacing the I/O board is a necessary step.

This repair takes some minimal disassembly, including dealing with internal components and using small tools in the form of screwdrivers. There is no soldering, but be gentle with brittle ribbon cables. Before starting, power off the device completely and take out the battery to prevent electrical harm.
