TECHNOLOGIES FOR FAST LOW-POWER STARTUP OF A COMPUTING DEVICE

摘要

Technologies for fast low-power startup include a computing device with a processor having a power management integrated circuit. The computing device initializes platform components into a low-power state and determines, in a pre-boot firmware environment, the battery state of the computing device. The computing device determines a minimum-power startup (MPS) configuration that identifies platform components to be energized and determines whether the battery state is sufficient for the MPS configuration. If sufficient, the computing device energizes the platform components of the MPS configuration and boots into an MPS boot mode. In the MPS boot mode, the computing device may execute one or more user-configured application(s). If the battery state is sufficient for normal operation, the computing device may boot into a normal mode. In the normal mode, the user may configure the MPS configuration by selecting features for the future MPS boot mode. Other embodiments are described and claimed.

主权项

1. A computing device for low-power booting, the computing device comprising:
a power management module to (i) initialize a plurality of components of the computing device in a low-power state and (ii) determine, in a pre-boot firmware environment, a battery state of the computing device; a minimum-power startup configuration module to (i) determine, in the pre-boot firmware environment, a minimum-power startup configuration, wherein the minimum-power startup configuration identifies one or more components of the plurality of components to energize in a minimum-power startup boot mode, and (ii) determine, in the pre-boot firmware environment, whether the battery state is sufficient for the minimum-power startup configuration; and a boot device selection module to boot the computing device in the minimum-power startup boot mode in response to a determination that the battery state is sufficient for the minimum-power startup configuration, wherein to boot in the minimum-power startup boot mode comprises to selectively energize the one or more components of the computing device based on the minimum-power startup configuration.
