    摘要: An illuminated keyboard that may be used for providing inputs to a computer. The keyboard includes a keyboard base pan and a plurality of input keys having keycaps that may be pressed by a user. An electroluminescent lamp, in the form a flat panel, is sandwiched between the keyboard base pan and the keycaps to illuminate the keyboard during use.

    摘要: A method and apparatus of controlling the brightness level of an LCD display. The brightness of a display having two light bulbs may be controlled by illuminating only one bulb to provide a relatively low brightness level or by illuminating both bulbs to provide a relatively high brightness level. This method and apparatus may be particularly useful in AC/DC powered devices, as a single bulb may be lit when the device is operating on DC power to conserve battery power, and both bulbs may be lit when the device is operating on AC power to provide enhanced brightness.

    摘要: A computer system that is configured to wirelessly access a local area network is further configured to search for the availability of wireless access points when the notebook computer is powered-off. A computer user activates this powered-off seek mode by pressing a button mounted on the outside cover of the computer. Activation of this button then activates a power supply within the notebook computer that powers a wireless communication module. The remaining power supplies in the computer system, however, are not turned on. Once the wireless communication or radio module is powered, a side-band signal to the normal universal serial bus communication activates the wireless access seek mode. Once a determination is made by the wireless communication module, that determination is passed to the user in the form of a light emitting diode which indicates the availability or nonavailability of a wireless access point in range.

    摘要: A computer system incorporating capabilities for displaying the audio disk track number when the computer system is playing an audio disk. The computer system determines if a disk is present in the disk drive. If a disk is present, the computer system determines if an audio disk is present in the disk drive. If so, the computer system then monitors the disk drive. When the audio disk is played by the disk drive, the computer system displays the audio disk track number. The computer system then periodically polls the disk drive to update the audio disk track number. The computer system displays a battery gauge status when the audio disk track number is not being displayed. The status display is visible when the portable computer is in either an open or closed state.

    摘要: A computer system is capable of playing audio CDs in a CD-ROM drive independent of the operating system by using an embedded CD-ROM drive application or a CD-ROM drive controller. When an audio CD mode switch of the computer system is in an “on” state and the main power switch of the computer is in an “off” state, the computer system is in an audio CD mode. When the computer is placed in such an audio CD mode, the computer either loads the embedded CD application from a non-volatile memory region such as read-only-memory (ROM) region or enables the CD-ROM drive controller of the CD-ROM drive to receive a CD selection and transmit the selections to the CD-ROM drive. The embedded CD application includes an embedded CD-ROM device driver for driving the CD-ROM drive to process audio CDs, power-on-self test (POST) code for selectively powering and initializing hardware devices in the computer system, initialization code for the embedded CD-ROM device driver, and system management interrupt/keyboard controller interface code used for processing the selection of a CD button of the computer system.
