`The ‘933 Patent
`
`1. Power supply equipment comprising:
`
`[1.a.] an adapter to convert power from a power source, external to the adapter,
`to DC power for powering an electronic device,
`
`[1.b.] the adapter including circuitry for producing an analog data signal for
`use by the electronic device to control an amount of power drawn by the
`electronic device; and
`
`[1.c.] a cable having proximal and distal ends, the proximal end being
`electrically coupled to the adapter and the distal end terminating in an
`output connector, the output connector including:
`
`[1.d.] a plurality of conductors to transfer the DC power and the analog data
`signal to the electronic device; and
`
`[1.e.] circuitry to receive a data request from the electronic device and
`in response transmit a data output to the electronic device
`to identify the power supply equipment to the electronic device.

`
`1. Power supply equipment comprising:
`
`[1.a.] an adapter to convert power from a power
`source, external to the adapter,
`to DC power for powering an electronic device,
`
`[1.b.] the adapter including circuitry for
`producing an analog data signal for
`use by the electronic device to control an amount
`of power drawn by the electronic device; and
`
`[1.c.] a cable having proximal and distal ends,
`the proximal end being electrically coupled to the
`adapter and the distal end terminating in an
`output connector, the output connector
`including:
`
`[1.d.] a plurality of conductors to transfer the DC
`power and the analog data signal to the electronic
`device; and
`
`[1.e.] circuitry to receive a data request from
`the electronic device and in response transmit a
`data output to the electronic device to identify the
`power supply equipment to the electronic device.

`
`If the power detection circuit 74 detects incoming
`AC power, switch 75 is closed and the AC
`identification circuit 77 is activated, thereby
`transmitting a data signal on line 42 indicating that
`the DC power carried on DC power lines 38 is
`generated from an AC power source. If, however,
`the power detection circuit 74 detects incoming DC
`power, switch 76 is closed and the DC identification
`circuit 78 is activated, thereby transmitting a data
`signal on line 42 indicating that the DC power
`carried on DC power lines 38 originates from a DC
`power source. The data signal carried on line 42 is
`used by the power management components of the
`information handling system to implement various
`power management functions. For example, if the
`data signal on line 42 indicates that the external
`power source is AC, the power management
`components may allow the battery to be fully
`charged and the various system components, such
`as the display, to operate at full power. If, on the
`other hand, the data signal on line 42 indicates that
`the external power is from a DC source, the power
`management components may limit the charging of
`the battery and also limit the power consumption of
`the various system components.

`
`1. Power supply equipment comprising:

`
`
`
`
`
`[1.a.] an adapter to convert power from a power
`source, external to the adapter,
`to DC power for powering an electronic device,
`
`[1.b.] the adapter including circuitry for
`producing an analog data signal for
`use by the electronic device to control an amount
`of power drawn by the electronic device; and
`
`[1.c.] a cable having proximal and distal ends,
`the proximal end being electrically coupled to the
`adapter and the distal end terminating in an
`output connector, the output connector
`including:
`
`[1.d.] a plurality of conductors to transfer the DC
`power and the analog data signal to the electronic
`device; and
`
`[1.e.] circuitry to receive a data request from

`
`In order to determine its power source and optimize
`its performance, a controller 260 included within the
`portable HIS device 101 sends a request signal to
`one or more power peripherals over a bi-directional
`PSID line 250 to request PSID information. Each
`power peripheral, which is queried, sends a response
`signal over the PSID line 250. The response signal
`includes the requested PSID attribute information.
`For example, a response may include information
`such as ‘DC 150’ or ‘AC 100’. The DC 150 may
`indicate a DC type power source rated to operate at
`150 watts, and the AC 100 may indicate an AC type
`power source rated to operate at 100 watts.

`
`The physical arrangements for association of a
`memory chip with each powered device are subject
`to considerable variation. For new devices,
`preferably the chip may be built into the device; for
`already-existing devices the chip may be built into a
`new power cable (preferably into one of the
`connectors at the two ends of the cable) for each
`device.

`
`In this port-r configuration, identification information
`is supplied from a memory 132r housed in the far-
`end connector 138r. This port-r three-wire cable
`configuration is conceptually related to the
`corresponding two-wire form, just discussed, at the
`second occupied port j.
