Lenovo can prevent self-repair by implementing measures such as using proprietary components and designs that are difficult for users to access or repair without specialized tools or knowledge. They can also void warranties if a device is opened or repaired by anyone other than authorized technicians. Additionally, Lenovo can provide limited access to repair manuals or guides, making it challenging for users to successfully repair their devices on their own. By controlling access to parts, tools, and information, Lenovo can discourage self-repair and encourage customers to seek professional assistance for any issues with their devices. **
