Which of these tools is recommended for servicing Lenovo systems?

The spudger is the recommended tool for servicing Lenovo systems because it is designed specifically for safely prying apart components without damaging them. This plastic or sometimes nylon tool is ideal for opening cases, separating connectors, and assisting in the repair process without causing harm to delicate internal parts. It minimizes the risk of scratches and other physical damage that may occur with metal tools, ensuring that the maintenance of the Lenovo systems is done effectively and safely.

Other tools, such as a hammer, are not suitable for sensitive electronic devices, where precision and care are crucial. A soldering iron, while useful in certain repair contexts, is not appropriate for all servicing tasks and involves a risk of damaging components if not handled properly. Pliers may be used in some instances, but they lack the finesse required for delicate components and can potentially cause more harm than good during repairs. Thus, for general servicing of Lenovo systems, a spudger is the most suitable and effective tool.
