When the notebook is working, the fan will run at high speed. The fan running at high speed will cause dust to enter the interior from the heat dissipation holes at the bottom, causing damage to the fan and motherboard. Serious dust accumulation on the computer will increase the load on the computer and make a sizzling sound.
The steps to repair the fault are as follows:
1. Prepare dust cleaning tools. The tools needed are cross-bit screwdriver, alcohol, brush, sanitary napkin, hair dryer, CPU Thermal silicone grease.
2. Turn the notebook over and use a Phillips screwdriver to unscrew the screws on the motherboard cover. Open the back cover, find the area that needs to be cleaned, and store the screws in their respective locations to prevent them from being lost.
3. Remove the fan, blow it with a hair dryer, and then use a brush to blow and brush at the same time. You can directly use a brush to clean the dust on the circuit board.
4. Replace with new silicone grease so that the radiator is in closer contact with the CPU to achieve good heat dissipation.
