Abstract: Devices, systems and methods are disclosed for quickly readying a device when charging a dead battery. For example, a device may enter a hibernation mode when the battery becomes critically low and may resume normal operation from the hibernation mode when an external power source is connected to the device. While the battery is critically low but the device is connected to the external power source, the device may generate a visible indication, such as a watermark, and apply the watermark to content to allow a user to control the device while indicating to the user that the battery is critically low and should not be removed from the external power source. Thus, the device may reduce user-perceived latency from when the external power source is connected to when the device resumes system interactivity (e.g., being responsive to user input).

Abstract: Accessory device power management techniques are described in which a power exchange state for a system including a host computing device, an accessory device, and an adapter is recognized. Power exchange states may be defined according to relative states of charge (RSOC) and connection status for the system components and mapped to power management control actions. Responsive to the recognition of a current power exchange state, corresponding power management control actions may be ascertained and applied to jointly manage power for the system. For instance, the host device may draw supplemental power from a power source associated with an accessory device (e.g., a battery or power adapter) or supply power for use by the accessory device according to different states. Power exchanges may also be managed in accordance with capabilities of the accessory device identified based on authentication of the accessory device.

Abstract: In an embodiment, a system includes a memory controller that includes a memory cache and a display controller configured to control a display. The system may be configured to detect that the images being displayed are essentially static, and may be configured to cause the display controller to request allocation in the memory cache for source frame buffer data.

During times that the display is dynamically changing, the frame buffer data may not be cached in the memory cache and the power management configuration may permit the shutting down/size reduction in the memory cache.

Abstract: The malfunction of a system caused by data managed by system firmware is prevented. A firmware ROM 100 is provided with a code area, a default area, and variable areas. Data (CV) fundamental to pre-boot created by a UEFI are written to the variable area. Global variables (GV) defined by the UEFI and data (UV) created by an OS are written to the variable area. The variable area is a recording area capable of being write-locked in the firmware ROM. The UEFI write-locks the variable area after completion of the pre-boot. Thus, the rewriting of CV by the OS can be prevented.
