Patent number: 9110664Abstract: A secondary graphics processor control system includes a secondary graphics processor. A controller is coupled to the secondary graphics processor. The controller detects the start of an application that is associated with a secondary graphics processor and then determines a power capability of a battery. The controller then either prevents enablement of the secondary graphics processor if the power capability is below a predetermined threshold such that only a primary graphics processor processes graphics for the application, or allows enablement of the secondary graphics processor if the power capability is above the predetermined threshold such that the secondary graphics processor processing graphics for the application. The primary graphics processor may be an integrated graphics processing unit (iGPU) provided by a system processor that is mounted to a board, and the secondary graphics processor may be a discrete graphics processing unit (dGPU) that is coupled to the board.Type: GrantFiled: April 20, 2012Date of Patent: August 18, 2015Assignee: Dell Products L.P.Inventors: Thomas P. Lanzoni, Ajay Kwatra, Randall E. Juenger

Patent number: 7120805Abstract: An energy discharge resistance is isolated from storage capacitance containing a voltage charge until power is removed from the storage capacitance. Then the discharge resistance may be coupled to the storage capacitance to drain residual charge therefrom. The discharge resistance is coupled to the storage capacitance when external power is removed and is un-coupled from the storage capacitance when external power is applied to the storage capacitance. In this way, unnecessary power draw during operation or standby of an electronic system is substantially eliminated.Type: GrantFiled: April 11, 2003Date of Patent: October 10, 2006Assignee: Dell Products L.P.Inventors: Joshua N.

Patent number: 7102255Abstract: An external power adapter prevents damage to contacts of power connectors by reducing current in-rush when the powered-up external power adapter is coupled to an information handling system. A control signal from the information handling system is used to initiate a voltage output of the external power adapter such that substantially no voltage is present on the contacts of the power connectors until the control signal is detected by the external power adapter. The external power adapter may determine the presence of an electrical load before applying the output voltage to the information handling system. The output voltage may be ramped from substantially no voltage to operating voltage over a period of time.Type: GrantFiled: February 24, 2003Date of Patent: September 5, 2006Assignee: Dell Products L.P.Inventors: Ajay Kwatra, Robert Allen, Kwabena Asante
