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.

Delayed shut down of a computer

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.

Managing memory fragmentation in hardware-assisted data compression

Methods and apparatus for scheduling and controlling power management activities are disclosed. An example method includes detecting, by a computing device, playback of video content at a frame rate that is greater than a predetermined threshold frame rate. The example method further includes, in response to the detection of the playback of video content at the frame rate greater than the threshold frame rate, overriding a screen dimming operation of the computing device.

Conditional power management activities

A method and system detect temperatures of multiple zones of a computer system using sensors distributed across the computer system. For each of the sensors, the system may determine whether a detected temperature associated with the sensor exceeds a predetermined value. If the detected temperature exceeds the predetermined value, the system may cool at least one of a plurality of devices of the system, based on a proximity of the at least one of the plurality of devices to the sensor.

Delayed shut down of computer

Methods and apparatus for scheduling and controlling power management activities are disclosed. An example method includes automatically scheduling a wake-up alarm for a computing device and transitioning the computing device from an active power state to a first low power state. The example method also includes, in response to occurrence of the automatically scheduled wake-up alarm, transitioning the computing device from the first low power state to the active power state and transitioning the computing device from the active power state to a second low power state, where the second low power state is a lower power state than the first low power state.

Data structures and state tracking for network protocol processing

A computer-implemented method for determining activity-based battery life duration for a battery operated device, comprising: identifying, from among a plurality of tasks, one or more current tasks being performed by a user on a battery operated device, determining, from among the plurality of tasks, one or more future tasks that are likely to be performed by the user and that are different than the one or more current tasks and calculating a battery life duration for one or more of the plurality of tasks based on the one or more current tasks being performed by the user and the one or more future tasks that are likely to be performed by the user. Systems and computer-readable media are also provided.

Activity-based remaining battery life

A method may include operating a device in a first power mode, setting flag(s), each flag representing an executing task, detecting a request to place the device in a second power mode. The second power mode consumes less system resources than the first power mode, and delaying the transition to the second power mode by placing the device in a third power mode that consumes less system resources than the first power mode but more than the second power mode. While in the third power mode, the method may include estimating an amount of system resources required for each of the task(s), determining if the total estimated amount of system resources to complete each of the task(s) exceeds one or more system resource threshold values, and if the estimated total amount of system resources exceeds the one or more system resource threshold values, ceasing execution of the task(s).

Delaying the initiation of transitioning to a lower power mode by placing a computer system into an intermediate power mode between a normal power mode and the lower power mode

A method includes operating a computing device in a first power mode and a first operating state. The first operating state includes first operating state information stored in a volatile memory. The method includes receiving a first request to change the power mode from the first power mode to a second power mode. In response to receiving the first request, a sub-portion of the first operating state information that includes less than all of the first operating state information is stored in a non-volatile memory. The method includes receiving a second request to change the power mode from the second power mode to the first power mode. In response to receiving the second request, the computing device is restored to the first power mode, and is placed in a second operating state, by re-creating a portion of the first operating state information.

Intelligent selection of operating state upon change of power state

Described are data structures, and methodology for forming same, for network protocol processing. A method for creating data structures for firewalling and network address translating is described. A method for creating data structures for physical layer addressing is described. A method for security protocol support using a data structure is described. A method for creating at least one data structure sized responsive to whether a firewall is activated is described. A data structure for routing packets is described. A method of forming hashing table chains is described. Additionally, method and apparatus for tracking packet states is described. More particularly, Transmission Control Protocol ('TCP') tracking of states for packets is described. In an embodiment, a division between software states and hardware states is made as a packet is processed by both software and hardware. Additionally, method and apparatus for network protocol processing are described. For example, a packet for network address translation having a media access control header is obtained, from which information, including the media access control header, is obtained. The information is parsed into one or more data structures. It is determined whether a network processing unit is in a first round processing mode, or a second round pass-through mode.

A method for identifying a failed network interface card in a system having two NICs configured as a team includes the steps of transmitting a first data packet from the first NIC to a third NIC, wherein the third NIC is not a member of the team, and transmitting a second data packet from the first NIC to the second NIC or from the second NIC to the third NIC, depending on whether the third NIC responds to the transmission of the first data packet. One advantage of the disclosed method is that it specifically identifies which NIC within the team has failed, which is something that cannot be determined by simply exchanging packets between the two NICs.

Technique for identifying a failed network interface card within a team of network interface cards

According to one general aspect, a method may include operating a computing device in a first power mode. The method may also include executing, by a processor of the computing device, at least one non-interactive task. The method may also include detecting, by a processor of the computing device, a request to place the computing device in a second power mode, wherein the second power mode consumes less system resources than the first power mode. The method may further include delaying the transition of the computing device to the second power mode until either the completion of the non-interactive task or an overriding triggering event.
