OneKey Theater button
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
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.
