Abstract: Systems, devices, and methods for managing fragmentation in hardware-assisted compression of data in physical computer memory which may result in reduced internal fragmentation. An example computer-implemented method comprises: providing, by a memory management program to compression hardware, a compression command including an address in physical computer memory of data to be compressed and a list of at least two available buffers for storing compressed data; using, by the compression hardware, the address included in the compression command to retrieve uncompressed data; compressing the uncompressed data; and selecting, by the compression hardware, from the list of at least two available buffers, at least two buffers for storing compressed data based on an amount of space that would remain if the compressed data were stored in the at least two buffers, wherein each of the at least two selected buffers differs in size from at least one other of the selected buffers.

Abstract: A computer-implemented computer shut-down method includes identifying that a computing device has been moved from an open configuration in which input and output mechanisms on the computing device are accessible to a user, to a closed configuration in which at least some of the input and output mechanisms are inaccessible to a user; starting a shut-down timer in response to identifying that the computing device has been moved from the open configuration to the closed configuration; waiting a predefined time period, as established by the shut-down timer, and determining from the shut-down timer that the computing device can be transitioned from an active state into a sleep state in which power consuming components of the computing device are powered down; and transitioning the computing device from the active state to the sleep state upon determining that the computing device can be transitioned.
