A power adapter has a solenoid actuated retaining latch controlled by an electronic circuit that detects the presence or absence of AC mains voltage. When the assembled AC-DC adapter and plug assembly are removed from the wall, the latch detects removal and unlocks the plug assembly for easy removal without undue force required by the user. The circuit is designed for minimal power consumption, and the solenoid only consumes power when it is engaging or disengaging the latch.

A system, method, and computer program product are provided for merging two or more supply rails into a merged supply rail. The method comprises receiving two or more current measurement signals associated with two or more supply rails, selecting one supply rail from the two or more supply rails, based on the current measurement signals, and enabling the selected supply rail to source current into a merged supply rail.

A dynamic multiple input rail switching unit includes a plurality of DC input voltage rails and a rail switching section coupled to the plurality of DC input voltage rails that is configured to individually connect selected ones of the plurality of DC input voltage rails to a switched rail output. The dynamic multiple input rail switching unit also includes a rail selection section that is coupled to the rail switching section and configured to dynamically choose the selected ones by balancing rail supply currents from the plurality of DC input voltage rails based on rail supply current capacity margins and a switched rail output current. A dynamic multiple input rail switching unit operating method, and a dynamic multiple input rail power converter are also provided.

Techniques for selecting a boot display device in the multi-GPU configured computing device include a graphic initialization routine for determining a topology of a plurality of GPUs. It is then determined if a display is coupled to any of the plurality of GPUs. The determination of whether the display is coupled to a GPU is communicated to the other of the plurality of GPUs based upon the determined topology. Thereafter, selection of a given GPU as a primary boot device, by a system initialization routine, is influenced by representing each GPU not coupled to the display as a graphics device and the GPUs coupled to a given display as the primary boot device if one or more displays are coupled to GPUs, and by representing the given GPU as the primary boot device and all other GPUs as graphics devices when the display is not coupled to any of the GPUs. In addition or in the alternative selection of the given GPU as the primary boot device may be influenced by hiding the expansion ROM of GPUs not coupled to a display.

A RAID system is provided which can be implemented as a hardware RAID system while avoiding certain shortcomings of previous RAID systems. The RAID system makes it possible to avoid or reduce the number of buffers or processors and can take advantage of drive logic to achieve RAID functions or enhancements. RAID functionality can be provided in a manner to accommodate one or more ATA drive interfaces. To avoid drive replacement problems, host requests for drive serial numbers are responded to with a mirror serial number. In one embodiment, the read address is used to select which drive will perform a read operation.
