Chapter 2. Learning the basics• Performing dust cleaningDust tends to accumulate around the heat sink of the computer’s CPU overtime, reducing the dissipation capability of the heat sink. You can reduce theamount of accumulated dust by performing dust cleaning. To perform dustcleaning, repeatedly press the thermal management button until ishighlighted. Dust cleaning will start after about three seconds.When dust cleaning is activated, the heat dissipation fan spins at high andlow speed alternatively to allow dust to be discharged. A complete dustcleaning process takes several minutes to complete. You can cancel theprocess at any time by switching the computer to standard, super silent orefficient thermal dissipation mode.Upon completion, the computer returns to the previous mode when dustcleaning was activated.Note: We recommend you perform dust cleaning at least once a month to reduce theamount of dust accumulation around the heat sink. Place your computer in a cleanenvironment with good ventilation when performing dust cleaning.22
