Open the computer case
Give your computer a "power-off solution" first, and then boldly open its "inner world"-computer chassis.
Looking for model identification
Look for the small model logo on the motherboard printed circuit board. Usually it will hide shyly at the edge or corner of the motherboard.
Search for relevant information on the Internet.
Once found, you can explore the details of this model in the ocean of the Internet, and learn about its specific model and hardware specifications.
Identification of motherboard version
Motherboard models usually have a mysterious combination of letters and numbers, such as "D4" and "D5". In fact, it is the motherboard version of logos, which may represent the difference of hardware specifications.
Different models of motherboards
However, don't worry, although the hardware of D4 and D5 may be different, their basic functions and usage are basically the same. So different models of motherboards will not have much impact on your computer experience.
