Common issues include broken screens, malfunctioning keyboards, and faulty power supplies. Technicians use various tools and techniques to diagnose problems and restore functionality. The process typically starts with identifying the issue, followed by disassembling the device to access the damaged parts. Once the repair is completed, the device is reassembled and tested to ensure it works properly. Proper hardware maintenance can extend the lifespan of devices and improve their performance.
