2. Description of the Related Art
As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option available to users is information handling systems. An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes thereby allowing users to take advantage of the value of the information. Because technology and information handling needs and requirements vary between different users or applications, information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in information handling systems allow for information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.
An increasingly common use of information handling systems, particularly portable systems, is for the display of multimedia information, such as presentations and videos. For instance, portable information handling systems are often used by business people to display presentations to groups through a projector with presentations such as Powerpoint. As another example, portable information handling systems are often used for entertainment by the playing of DVD movies with a DVD drive device. Generally in order to use an information handling system to display multimedia information, the operating system of the information handling system brings all devices to an operational status and maintains all devices in the operational status whether or not a particular device supports the display of multimedia information. For instance, while a user plays a DVD movie on an information handling system disc drive, the operating system typically maintains networking devices and antivirus applications operational even though these devices and applications are not needed to play the DVD movie. Unused but enabled devices and applications waste CPU cycles, such as by unnecessary scans for a network, so that, under some circumstances the presentation of the multimedia information is unnecessarily and adversely impacted.
A difficulty that often arises with the presentation of multimedia information through a portable information handling system is that the internal battery charge expires prematurely, such as in the middle of a lengthy DVD movie. Another difficulty that arises is that presentation of the multimedia information is delayed by the normal boot process that the operating system uses to bring all of the processing components and automatically initiated programs to a normal operational state. Although portable information handling systems have modes of operation that reduce power consumption to preserve battery life, such as shutting down the display or otherwise hibernating, those modes of operation typically do not take effect while the information handling system is in active use, such as during presentation of multimedia information. Some specialized systems have been developed to provide “instant on” for playing DVD movie or CD audio information with reduced start-up time and battery consumption. However, such specialized systems typically incorporate a unique custom player with an independent operating system, such as in the BIOS, custom hardware or a separate hard disc drive partition. The use of custom hardware and software processing components increases system design and manufacture cost.
Therefore a need has arisen for a system and method which leverages multimedia capabilities available in an information handling system normal operation mode with reduced power consumption and start-up time.
In accordance with the present invention, a system and method are provided which substantially reduce the disadvantages and problems associated with previous methods and systems for presenting multimedia information at an information handling system. Information handling system processing components selectively boot to a multimedia mode having multimedia processing components enabled to support presentation of multimedia information and non-multimedia processing components disabled to reduce power consumption and boot time.
More specifically, an information handling system having plural processing components managed in normal operation by an operating system includes a multimedia selector switch, such as an alternative power switch, that boots the information handling system to a multimedia mode. A multimedia module applies a modified boot that enables substantially only those processing components that support a desired multimedia application and leaves the remaining processing components disabled. For instance, to play a DVD movie in a disc drive, the multimedia module commands a multimedia boot of the operating system to enable devices, such as the CPU, memory, video, audio and input devices, and applications, such a movie player, that support display of the movie. The multimedia module commands the multimedia boot to not enable devices, such as network interface cards (NIC), wireless interfaces, modems, communication ports and unused buses, and applications, such as antivirus software, that do not support display of the movie. In addition, the multimedia module bypasses boot procedures not needed to operate the multimedia application, such as the POST tests, and restricts processing power consumption to a level that is sufficient to support display of multimedia information, such as throttling CPU cycles to a lower level after boot is complete.
The present invention provides a number of important technical advantages. One example of an important technical advantage is that information handling system boot time and power consumption are reduced in a multimedia operating mode compared with a normal operating mode. Boot time is reduced since the operating system does not have to start up drivers for unused devices, does not have to perform unneeded systems tests and does not have to initiate unneeded applications or connect to networks. Power consumption is reduced since fewer devices receive power and less computing cycles are necessary. The reduced boot time and reduced power consumption improve the user experience with a more instant-on perception and greater multimedia presentation endurance.
The present invention may be better understood, and its numerous objects, features and advantages made apparent to those skilled in the art by referencing the accompanying drawings. The use of the same reference number throughout the several figures designates a like or similar element.
Information handling system boot to a multimedia operating mode supports presentation of multimedia information with reduced boot time and power consumption compared to a normal operating mode by selectively enabling multimedia processing components and disabling non-multimedia processing components. For purposes of this disclosure, an information handling system may include any instrumentality or aggregate of instrumentalities operable to compute, classify, process, transmit, receive, retrieve, originate, switch, store, display, manifest, detect, record, reproduce, handle, or utilize any form of information, intelligence, or data for business, scientific, control, or other purposes. For example, an information handling system may be a personal computer, a network storage device, or any other suitable device and may vary in size, shape, performance, functionality, and price. The information handling system may include random access memory (RAM), one or more processing resources such as a central processing unit (CPU) or hardware or software control logic, ROM, and/or other types of nonvolatile memory. Additional components of the information handling system may include one or more disk drives, one or more network ports for communicating with external devices as well as various input and output (I/O) devices, such as a keyboard, a mouse, and a video display. The information handling system may also include one or more buses operable to transmit communications between the various hardware components.

In order to provide a system boot that is better optimized for presentation of multimedia information, a multimedia selector switch 44 is disposed on information handling system 10 to accept a user request for boot to a multimedia mode. Multimedia selector switch 44 is selectable between normal and multimedia positions that control the input of power switch 42 or offers a separate power switch for initiation of a multimedia mode. Alternatively, multimedia selector switch may be configured as a displayed selection on LCD 26 or an automated selection integrated with one or more audio or video devices, such as an automated selector initiated by insertion of a DVD into CD/DVD drive 24.
Selection of a multimedia mode is communicated to a multi-media module 46 interfaced with multimedia selector switch 44. Multimedia module 46 sets a multimedia flag 48 that alerts CPU 14 to the multimedia mode boot selection and also defines the processing components enabled by the multimedia boot of operating system 12. The multimedia devices enabled in a multimedia boot are substantially only predetermined processing components that support a desired multimedia application. Examples of devices enabled in a multimedia boot include the information handling system CPU, memory, video, audio and input devices plus inconsequential devices that have a minimal impact on power and boot time constraints. The video and audio devices might include a DVD drive, LCD and speakers to support display of a DVD movie with a movie player application. Examples of devices that are not enabled include NICs, wireless interfaces, Cardbus, IrdA, soft modems, 1394 ports, communication ports and USB. A multimedia configuration graphical user interface 46 supports selection of various configurations achieved by a multimedia boot. For instance, a configuration that plays DVD movies may disable the USB while a configuration that plays a presentation for a projector may enable the USB to communicate the presentation information to the projector.
In addition to selecting devices for boot to a multimedia mode, multimedia module 46 manages the boot to optimizes system performance. For instance, POST tests are bypassed to reduce boot time and CPU clock speed is managed to have a high performance setting during boot to reduce boot time followed by a throttling to a reduced performance setting to reduce power consumption. Multimedia module 46 shuts down non-multimedia devices with power control at BIOS 20 to hide them from discovery by operating system 12, which may otherwise attempt to power up unused devices. Multimedia module 46 re-orders and omits boot actions by operating system 12, such as powering up a DVD drive substantially simultaneously with a hard disc drive to reduce time until the DVD drive is ready, shutting down operating system functions like automated saves or searches for network connections, and preventing automated initialization of utility programs like antivirus applications.
