Abstract: The disclosed embodiments provide a system that manages power allocated through a set of bus interfaces on a computer system. During operation, the system obtains a first request for revocable current beyond a reserved current for a first bus interface from the set of bus interfaces, wherein the request is associated with a first device connected to the first bus interface. Next, the system allocates the revocable current to the first bus interface from an extra-current budget for the set of bus interfaces. Upon detecting a connection of a second device that requires non-revocable current over the extra-current budget to a second bus interface from the set of bus interfaces, the system transmits a first notification to the first device to relinquish the revocable current. Finally, the system allocates the non-revocable current to the second device from the relinquished revocable current.

Abstract: One embodiment of a display backlight driver integrated circuit can be configured for operation in at least two different ways. A first method transfers data from an EEPROM to hardware registers prior to regular operation. A second method also transfers data from an EEPROM to registers. However, hardware registers can be overwritten with data accepted from a control bus, prior to regular operation. A keyboard driver IC can detect the presence or absence of a cable to an LED. If the cable is absent, the driver IC will not supply power for the LED. One embodiment of a keyboard and display backlight control system can be configured to allow substantially independent operation.

Abstract: An electronic device is disclosed that redirects light escaping from a display assembly light source to an illuminable region of the electronic device. In some embodiments, the electronic device includes a light guide panel arranged along a rear surface of the display assembly and configured to receive light escaping from a lateral side of the light source. The light guide panel can then be arranged to transport that light to a position behind the illuminable region and emit it back out in a focused beam having a size about the same as the illuminable region. In some embodiments the illuminable region can be a logo or device identifier.

Abstract: Memory packages, memory modules, and circuit boards are described. In an embodiment, single channel memory packages are mounted on opposite sides of a circuit board designed with a first side also designed to accept dual channel memory packages. Alternatively, dual channel memory packages may be mounted on a first side of a circuit board that is also designed to accept single channel packages on opposite sides.
