1. First of all, prepare a screwdriver, tweezers, cotton balls and detergent for notebooks (these are all delivered when buying notebooks in physical stores). These three tools are enough.

2. Then use a screwdriver to remove all the screws at the bottom of the notebook, and open the bottom case to remove the keyboard and C case on the notebook. In this way, you can basically see the whole picture inside the notebook. Then start cleaning up.

3. In fact, the cleaning process is also very simple. Use tweezers to hold a small cotton ball and then gently wipe it back and forth on the dusty place on the notebook motherboard and fan to clean it. Be careful not to rub too hard. Many small components are easy to wear.
