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.

Tools

Step 1

Remove Phillips #1 screws from the bottom of the Chromebook using a Phillips #1 screwdriver.
Ten 8 mm screws
Two of the screws are hidden by rubber caps along the rubber rest of the device. Use tweezers to get them out.

Step 2

Place the plastic opening tool into the edges between the front of the Chromebook and the back of it with the upper scoop of the opening tool facing upward.
Push down on the plastic opening tool to unhinge the top portion of the Chromebook from its lower portion. Opening the Chromebook all the way where the display touches the ground helps in opening up the top edge.
Use your hand to gently lift the top portion of the Chromebook from the bottom portion of it to avoid damaging the ribbon cables.

Step 3

Gently disconnect the ribbon cable connecting the trackpad to the motherboard.
Gently disconnect the ribbon cable connecting the keyboard to the motherboard.

Step 4

Pull the latch out on both the Input/Output board as well as the motherboard.
Gently remove the ribbon cable connecting the I/O board to the motherboard.

I was able to remove the IO board at this stage, without removing the battery.
