1. An information handling system comprising:
- a housing;
a processor disposed in the housing and operable to execute instructions to process information;
a memory disposed in the housing and interfaced with the processor, the memory operable to store the information;
a power supply disposed in the housing and operable to accept external power and convert the external power for powering the processor and memory;
an embedded controller interfaced with the power supply and operable to manage application of power to the processor and memory;
a communication hub supporting one or more communication ports, the one or more communication ports having a data and power interface to interact with an external device through a cable;
an external charging pad interfaced with a communication hub port, the external charging pad having a coil configured to provide wireless power transfer to a portable device; and
a power manager stored in non-transitory memory associated with the embedded controller, the power manager operable to coordinate power transfer to the charging pad independent of a power state of the processor and memory.

Abstract
A portable information handling system wirelessly charges from a charging pad powered from a source information handling system, such as by power transferred through a USB cable. Configuration information exchanged between the source information handling system and charging pad coordinates the power transfer, including the amount of power transfer and power transfer when the source information handling system is in a powered down state, such as an ACPI S3 or S5 state.

9. A method for charging a portable information handling system, the method comprising:
-
coupling a data cable from an information handling system to a charging pad, the data cable providing power to the charging pad; quantifying at the information handling system power available for transfer to the charging pad; exchanging configuration information between the information handling system and charging pad, the configuration information defining power transfer to the charging pad in plural power states of the information handling system; detecting a portable device disposed on the charging pad; and in response to detecting, transferring power through the data cable to the charging pad according to the configuration information and power state. - View Dependent Claims (10, 11, 12, 13, 14)
