Learning the basics Cap Sensor buttons Volume buttons b~d b Mute/Unmute c Volume down d Volume up OneKey Theater button e Lenovo OneKey Theater provides four scenario modes for using your computer in different ways: normal mode, movie mode, music mode, and picture mode. These modes are preset enhancements by Lenovo to improve visual and aural experiences. To select a desired mode, press the OneKey Theater button. . Note: To determine which mode is currently active, hover the mouse pointer over the program icon (located in the notification area of the desktop). The name of the active mode will then be highlighted above the icon temporarily. Thermal management button f 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, press the thermal management button. 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 pressing the thermal management button. 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. 20
