摘要:
An information handling system that includes a processor, a memory, a program, a battery, and a module. The module receives a request for first information associated with the battery from the program, accesses the first information, converts the first information into second information, and provides the second information to the program in response to the request.
摘要:
Methods and systems are disclosed for controlling microprocessor (CPU) performance modes utilizing sensed temperatures as an indication of CPU utilization. By recognizing that temperature can be used as an indication of CPU utilization, higher performance modes can be entered as temperature increases, and lower performance modes can be entered as temperature decreases.
摘要:
An information handling system can receive power from a wireless or wired power source. In response to determining the information handling system is coupled to the wired power source, the system decouples the wireless power source from providing power. In response to the system being decoupled from the wired power source, the information handling system couples the wireless power source to the system.
摘要:
A technique is disclosed for more fully utilizing the full voltage range of a battery driven battery output voltage when the battery output voltage is provided through voltage regulation circuitry. More particularly, when the battery output voltage drops to a level that is insufficient to support the desired output of the voltage regulation circuitry, the battery output voltage may be coupled to the voltage output in a manner bypassing at least a portion of the voltage regulation circuitry. In this manner additional voltage range of the battery output voltage may be utilized while still maintaining an output voltage within a desired output voltage range. In one embodiment, such a technique may be utilized in an uninterruptible power supply system.

An entertainment system includes an optical media drive operable to playback contents of an optical media and a storage device (SD) to store data. The SD includes a head to read and write the data, a detector input to detect the playback of the optical media and a control output to move the head in a predefined motion in response to the playback. The predefined motion, which occurs continuously at a predefined constant speed, prevents the SD from generating an unsolicited sound during the playback, thereby improving the multimedia experience. The predefined motion is disabled when the playback is disabled.

In a speaker assembly in a portable device information handling system, a battery is operable to provide power to the portable device. The battery includes a plurality of cells housed in a battery housing. A predefined number of cells included in the plurality of cells are removable to define a selective portion of the battery housing. The speaker assembly housed in a speaker container is installable in the selective portion. The dimensions of the battery housing having the speaker container installed in the selective portion are substantially unchanged. A terminal connector assembly having a plurality of electrical connectors couples the battery and the speaker assembly to external devices. The speaker assembly includes a speaker operable to output sound having a low frequency.

A power diagnostics module running on an information handling system initiates a power down state of the information handling system upon detection of a predetermined battery charge that is sufficient to allow the information handling system to recover from the power down state and run the power diagnostics module. The power diagnostics module runs on the predetermined charge to diagnose faults associated with the power system, such as failure of an external AC adapter, and to present the faults to an end user, such as at a display, with LEDs or through a network message.
