When replacing the system board in a notebook, which additional item should be ordered to ensure screw threads will lock properly?

When replacing the system board in a notebook, it is essential to ensure that all components are properly secured. The correct answer is to order a screw kit because during the replacement process, the existing screws may become damaged, worn, or stripped, which could prevent a secure fit. A dedicated screw kit would provide new screws specifically designed for the notebook model, ensuring that the threading will lock properly and maintain the structural integrity of the device.

This is especially important in laptops where the system board is a crucial component, and any improper installation can lead to various issues, including system instability or damage to other parts. Having the correct screws ensures that each part is held in place securely, reducing the risk of future problems.

In contrast, options like a battery pack or power adapter do not directly relate to the installation of the system board, as they are not involved in the physical securing of the components. A warranty extension, while beneficial for additional coverage, does not address the immediate need for proper installation hardware. Therefore, a screw kit is the appropriate choice to ensure that the system board is mounted correctly and functions as intended.
