Chapter 2. Learning the basics

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 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.
