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 about 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.
