The user may toggle a control switch to place the computer system in a secondary operational mode, determine when a computer system is in a secondary operational mode, and adjust a digital master volume control during the secondary operational mode. The portable computer system includes a status indicator for indicating when a computer is in a secondary operational mode, digital master volume control buttons operable in a secondary operational mode, and a control switch for placing the computer system in a secondary operational mode. The status indicator, volume control buttons, and control switch are preferably provided on a top surface of the bottom shell of the portable computer for convenient access by a user. As such, a user is capable of placing the computer system in a secondary operational mode and determining when the computer system is in a secondary operational mode without opening the portable computer case. A user is also capable of adjusting volume control during a secondary operation mode without the need to access a plurality of volume controls, sort through software to adjust the volumes of the audio sources, or open the portable computer case to visualize volume controls for the audio sources on the main display screen.
    • 处于关闭状态或打开状态的便携式计算机机箱允许用户对某些操作特征进行控制和监视。 用户可以切换控制开关以将计算机系统置于辅助操作模式,确定计算机系统何时处于辅助操作模式,并且在辅助操作模式期间调整数字主音量控制。 便携式计算机系统包括用于指示计算机何时处于辅助操作模式的状态指示器,在辅助操作模式下可操作的数字主音量控制按钮以及用于将计算机系统置于辅助操作模式的控制开关。 状态指示器,音量控制按钮和控制开关优选地设置在便携式计算机的底壳的顶表面上,以便用户方便地访问。 因此,用户能够将计算机系统置于辅助操作模式并且确定何时计算机系统处于辅助操作模式而不打开便携式计算机机箱。 用户还能够在辅助操作模式期间调节音量控制,而不需要访问多个音量控制,通过软件排序以调整音频源的音量,或者打开便携式计算机机箱以可视化音频的音量控制 来源于主显示屏。
