Introduzione

Following this guide will ensure a safe and easy way to replace the Input/Output Printed Circuit Board (I/O PCB) in your Samsung Series 9 (NP900X4B-A02) laptop. No other skills are required to to replace this board, which means anyone can accomplish this task.

The I/O PCB is the board that controls most of the interaction between a person and their computer. As with other circuit boards, a problem with your I/O PCB can be difficult to diagnose. Before replacing your I/O PCB, be sure that the board is the cause of the issue.

Before beginning this guide, ensure that your laptop is powered off and disconnected from its power source.

    • Ensure computer is unplugged and powered down before continuing.

    • Remove the ten screws along the base using a Phillips #000.

    • Use a Plastic Opening Tool to pry open the base .

    • The battery is now unobstructed from your view.

    • Before removing the battery, use the plastic opening tool to detach the ribbon wire cable that connects the battery to the motherboard.

    This step is completely unnecessary! There is no need to disconnect the battery for replacing the speakers for NP900X4B-A02.

    BTW, disconnecting the battery is quite tricky. As you can see in the photo, when trying to pull out the connector, it bumps into the connector next to it (on the left). The cables are stiff and you have to exert considerable force and risk hitting the cables with the tool you are using while disconnecting the battery. If you DO have to disconnect the battery for any reason, first unplug the connector to the left, under the battery's ribbon wire cable.
