Chapter 2. Learning the basics

Performing dust cleaning

Dust tends to accumulate around the heat sink of the computer’s CPU over time, reducing the dissipation capability of the heat sink. You can reduce the amount of accumulated dust by performing dust cleaning. To perform dust

cleaning, repeatedly press the thermal management button until is highlighted. Dust cleaning will start after three seconds.

When dust cleaning is activated, the heat dissipation fan spins at high and low speed alternatively to allow dust to be discharged. A complete dust cleaning process takes several minutes to complete. You can cancel the process at any time by switching the computer to standard, super silent or efficient thermal dissipation mode.

Upon completion, the computer returns to the previous mode when dust cleaning was activated.

Note: We recommend you perform dust cleaning at least once a month to reduce the amount of dust accumulation around the heat sink. Place your computer in a clean environment with good ventilation when performing dust cleaning.
