摘要： A computer system is provided which assures that display control signals provided to a display are properly sequenced despite the presence of ill-behaved application software. The risk of damage to displays which require control signals to be in a predetermined sequence is thus significantly reduced. An enable signal from the system's graphics controller is intercepted by a microcontroller. The microcontroller generate its own properly sequenced and timed display control signals in response to the enable signal from the graphics controller. The microcontroller controls a switching apparatus which couples clock and data signals from the graphics controller to the display at an appropriate time in the control signal sequence.

摘要： An emulation methodology utilizes increasing microprocessor performance characteristics and System Management Mode ("SMM") to emulate peripheral device functions in a computer system. The emulation methodology traps addresses associated with I/O between a CPU and one or more peripheral devices. After trapping the I/O instruction address, a system management interrupt issues, and the computer system enters the operating system independent SMM. The CPU executes SMM code which proceeds to pass instructions to the CPU which result in the complete or partial emulation of a peripheral device. When the peripheral device is completely emulated, it can be replaced, for example, with a less expensive, less functional component or possibly even eliminated without substitution. The emulation methodology also responds to asynchronous peripheral device user activity by again trapping an I/O instruction to the peripheral device, and using SMM code to emulate the peripheral device.

摘要： Communication between an information handling system and battery has improved reliability by repeated communications of information from the battery using different commands from the information handling system. A battery management unit responds to a first command from an information handling system by sending information stored at a first address associated with the command and then saving the first address at second address. A power manager of the information handling system sends a second command having the second address to the battery management unit. The battery management unit responds to the second command by retrieving the first address stored at the second address, retrieving information stored at the first address and sending the information to the power manager. The power manager restricts operations of the battery, such as charges or discharges, unless the information received in response to the first and second commands matches.

摘要： An information handling system which supports Pre-Boot Authentication (PBA) and which provides the ability for each authorized user of the system to have a unique ID and key at the BIOS level. In these systems, a user only needs knowledge of the traditional BIOS password only at the time the user is enrolled in the PBA feature. Later changes to the password do not have the effect of denying access to enrolled users.

摘要： A method for reducing the receipt of multiple signals in a portable information handling system (IHS) is closed including receiving a first signal corresponding to a detected lid position of the portable IHS. The method further includes determining if a first predetermined amount of time has elapsed and if the first predetermined amount of time has not elapsed, preventing the receipt of an additional signal corresponding to a change in the detected lid position. Further, a portable information handling system may include a lid, a base coupled to the lid and a sensor disposed on the lid or base, wherein the sensor detects a lid position. The system further includes a processor coupled to the sensor, wherein the processor generates a first signal corresponding to the lid position and the processor is operable to generate an additional signal corresponding to a change in the lid position.

摘要： A conversion methodology utilizes increasing microprocessor performance characteristics and System Management Mode ("SMM") to provide transparent support of hardware components that include features unsupported by executing application and operating system programs. In one embodiment, a PC system includes code that supports only conventional but unavailable communication interfaces. However, the PC system is equipped with a universal serial bus ("USB") controller. Although the USB controller is unsupported by the executing code by the application and operating system programs, the conversion methodology utilizes system management mode to facilitate transparent support for the USB controller. In SMM, a CPU executes SMM code independently of the operating system(s). The conversion methodology causes entry of SMM upon any I/O operation intended for the supported but unavailable conventional communication interfaces. The SMM code provides data from the USB controller in a format recognizable to the requesting non-supporting software. SMM code supports providing all da t that would otherwise be provided to supporting software.

摘要： A power consumption manager reduces inadvertent information handling system shutdowns by monitoring current discharge from a battery and commanding selected components of the information handling system to operate in a reduced power mode if current discharge exceeds a warning threshold. The power consumption manager recovers the selected components from the reduced power mode if the current discharge from the battery remains less than a recovery threshold. Monitoring of current discharge reduces inadvertent shutdowns from temporary surges in power demand from the battery and allows implementation of a reduced power configuration for the information handling system as total power discharge capacity of the battery drops with total charge available due to use of the battery over time.
摘要翻译：功率消耗管理器通过监视来自电池的当前放电来指示所选择的信息处理系统的组件，以便在电流放电超过警告阈值的情况下以降低功率模式工作，从而减少无意的信息处理系统关闭。如果当前从电池放电的电量保持小于恢复阈值，功耗管理器将从降低功耗模式中恢复所选择的组件。电流放电的监控减少了来自电池的电力需求的暂时浪涌的意外停机，并允许实现信息处理系统的降低的功率配置，因为随着电池使用时间的延长，电池的总功率放电容量会随着使用电池而有所下降。
