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. Be gentle with brittle ribbon cables. Before starting, power off the device completely and take out the battery to prevent electrical harm.
