This is a user manual for Lenovo IdeaCentre K3 series computers, which provides detailed instructions on hardware usage, rescue system usage, software usage, and common problem troubleshooting.
This manual begins with important safety information and a warranty guide, then details the computer’s hardware, including front‑panel controls such as the power switch, breathing‑light switch, USB ports, and rear‑panel connectors like the voltage selection switch, HDMI, and Ethernet ports. It also covers system recovery, driver installation, Lenovo account registration, and optional software features.
Later sections address common troubleshooting topics—display, sound, software issues, optical drive and hard‑disk handling, Windows‑specific notes—and provide daily maintenance advice, including cleaning methods and precautions to protect the system. This manual is written in Chinese.
