Abstract: Methods and apparatuses for re-instantiating a firmware environment that includes one or more firmware functions available at pre-boot time when transitioning the computing device from a first, higher power consumption state to a second, lower power consumption state. The firmware environment determines whether a cryptographic signature on a firmware volume is verified; whether hardware resources of the computing device requested by a manifest of the firmware volume are available; and whether a firmware module of the firmware volume is compatible with installed firmware of the firmware environment. If so, the firmware environment reserves space in a memory to accommodate resources used by the firmware module, and executes the firmware module with the computing device in the second, lower power consumption state.

Abstract: A power lock-up setting method and an electronic apparatus using the same are provided. The power lock-up setting method includes following steps. A trigger signal generated by a pressed power switch is received by a pin of a GPIO interface and transmitted to a control unit, such that the control unit starts the electronic apparatus, and a power-on-self-test of a logic processing unit is performed by a processing module. Whether the GPIO interface is set to a power lock-up state is determined by the logic processing unit. If so, a level of the pin is set to a disable level. An operating system is loaded by the processing module to perform an operating system booting process. Accordingly, when the electronic apparatus is under an operating environment of the operating system, the trigger signal is forbidden to be transmitted to the control unit when being generated again.

The computer system is operated in a working state and at least one stand-by state. The module includes a timer and an interrupt generation unit.

When the specific state is entered, the computer system enters the stand-by state, a PLL (phase lock loop) of the display module keeps turning on, and PLLs other than the PLL of the display module are turned off and the graphic module acquires a frame stored in a fixed area of a storing unit and displays the acquired frame on the display module.

Abstract: An access instruction associated with accessing a target location in a disk is obtained. A number of units until the target location is accessed is calculated. It is determined whether there is time for the group of logic to transition from a lower power state to an operational state; the determination is based at least in part on the number of units between a current location of a read head associated with the hard disk system and the target location which is different from the current location of the read head and a warm up time associated with the group of logic. If it is determined there is time, the group of logic is put into the lower power state.

Abstract: An information handling system having plural processing modules, such as an information handling system blade chassis having plural information handling system blades, allocates power by determining an actual load sharing power loss associated with plural power supplies and applying the actual load sharing power loss to determine how much power to allocate to the information handling system modules. A chassis manager determines actual load sharing power loss by retrieving power information from plural power supplies. The actual load sharing power loss replaces a worst-case load sharing power loss assumed value to increase the amount power available for allocation to the information handling system modules.
