计算机维修基本程序（Basic computer maintenance program） Basic procedures for computer maintenance I. observation Observation is the first method in the process of maintenance judgment, which runs through the whole maintenance process. Observation should be not only serious, but also comprehensive. What you want to see include: 1, the surrounding environment; 2, hardware environment. Including plug, seat and slot, etc.; 3, software environment; 4, user habits, process Two, minimum system approach The minimum system is the basic hardware and software environment that enables the computer to boot or run from the point of view of maintenance.
