Thermal management button
The thermal management button can be used to switch the computer
between different work modes and thus control the speed at which the heat
dissipation fan spins. You can choose between standard, super silent, or
efficient thermal dissipation
mode. You can also activate the dust cleaning
feature by pressing and releasing the thermal control button.
• Standard mode
Standard mode is the factory default mode. It is the recommended work
mode for most programs.
• Super silent mode
If your computer is not running large programs and you want a silent work
environment, switch your computer to super silent mode. To switch to super
silent mode, repeatedly press the thermal management button until
is
highlighted. The computer will switch to super silent mode after about three
seconds.
• Efficient thermal dissipation mode
If large programs are running, switch your computer to efficient thermal
dissipation
mode to allow more efficient thermal dissipation. To switch to
efficient thermal dissipation mode, repeatedly press the thermal
management button until is highlighted.
Note: The heat dissipation fan spins at relatively low speeds in super silent mode, and thus
dissipates less heat than in other modes. If large programs are running, the system
may lower the voltage of the CPU (central processing unit) automatically to decrease
the heat produced by the CPU. Consequently, you might experience lower system
performance when the computer is running in super silent mode.
