`1. Technical Field
`[0001]
`
`
`
`
`
`
`
`
`
`[0002] The present invention relates to an approach for
`
`
`
`
`
`
`
`connecting and charging a wireless keyboard. More particu-
`
`
`
`
`
`
`
`
`larly, the present invention relates to charging a wireless
`
`
`
`
`
`
`
`keyboard used in a slate computer by attaching the wireless
`
`
`
`
`
`
`
`
`keyboard to the slate computer and charging the keyboard
`
`
`
`
`
`using the slate computer unit.

`2. Description of the Related Art
`
`
`
`
`
`
`
`
`[0004]
`Slate computer systems are also referred to as tablet
`
`
`
`
`
`
`
`
`computer systems (tablet PCs). The name “slate” computer
`
`
`
`
`
`
`
`
`
`
`derives from the unit’s slate shape which is generally easy for
`
`
`
`
`
`
`
`
`
`a user to hold. Slate (tablet) PCs are often popular in situa-
`
`
`
`
`
`
`
`tions where use of a normal notebook computer is impracti-
`
`
`
`
`
`
`
`
`cal, unwieldy, or otherwise does not provide the functionality
`
`
`
`
`
`
`
`
`needed by the user. Wireless keyboards are often popular,
`
`
`
`
`
`
`
`especially with slate computers, because of their flexibility in
`
`
`
`
`
`
`
`
`placement which melds with the flexibility provided by the
`
`
`
`slate computer system.
`
`
`
`
`
`
`
`
`[0005] One challenge of slate computer systems that utilize
`
`
`
`
`
`
`
`wireless keyboards is that the wireless keyboard is powered
`
`
`
`
`
`
`
`
`
`by its own battery. Ifthe wireless keyboard runs out ofbattery
`
`
`
`
`
`
`
`
`
`
`power, the keyboard can generally not be used with the slate
`
`
`
`
`
`
`
`computer system without replacing the keyboard’s batteries
`
`
`
`
`
`
`
`
`
`(e.g., “AA,” “AAA,” etc.). This can be problematic due to the
`
`
`
`
`
`
`
`slate computer’s popularity in performing “field work” which
`
`
`
`
`
`
`
`may be a remote location distant from traditional battery
`
`
`
`
`
`suppliers such as stores and the like.
`SUMMARY
`
`
`
`
`
`
`
`
`
`
`It has been discovered that the aforementioned chal-
`[0006]
`
`
`
`
`
`
`
`
`lenges are resolved using an approach that determines
`
`
`
`
`
`
`
`
`whether keyboard power connection points that are included
`
`
`
`
`
`
`
`
`in a wireless keyboard are connected to system power con-
`
`
`
`
`
`
`nection points included in a computer system. In response to
`
`
`
`
`
`
`
`
`determining being that the keyboard power connection points
`
`
`
`
`
`
`
`
`are connected to the one or more system power connection
`
`
`
`
`
`
`
`
`points, power is sent from the computer system to the wireless
`
`
`
`
`
`
`
`
`keyboard. The power is transmitted through the system power
`
`
`
`
`
`
`
`connection points to the keyboard power connection points.
`
`
`
`
`
`
`
`Keyboard components included in the wireless keyboard are
`
`
`
`
`
`
`
`
`
`also powered using the power sent from the computer system.
`
`
`
`
`
`
`
`
`in response to determining that the keyboard power connec-
`
`
`
`
`
`
`
`
`
`tion points are not connected to the system power connection
`
`
`
`
`
`
`
`points, the keyboard components are powered included in the
`
`
`
`
`
`
`
`
`wireless keyboard by using a keyboard battery that
`is
`
`
`
`
`
`
`
`included in the wireless keyboard. One of the keyboard com-
`
`
`
`
`
`
`
`
`ponents that receives power is a wireless interface that con-
`
`
`
`
`
`
`
`nects the wireless keyboard to the computer system.
`
`
`
`
`
`
`
`[0007] The foregoing is a summary and thus contains, by
`
`
`
`
`
`necessity, simplifications, generalizations, and omissions of
`
`
`
`
`
`
`
`
`detail; consequently, those skilled in the art will appreciate

`access the system memory. Graphics controller 125 is also
`
`
`
`
`
`
`
`connected to Northbridge 115. In one embodiment, PCI
`
`
`
`
`
`
`
`
`Express bus 118 is used to connect Northbridge 115 to graph-
`
`
`
`
`
`
`
`ics controller 125. Graphics controller 125 is connected to
`
`
`
`
`
`
`display device 130, such as a computer monitor.
`
`
`
`
`
`
`
`
`[0023] Northbridge 115 and Southbridge 135 are con-
`
`
`
`
`
`
`
`
`
`nected to each other using bus 119. In one embodiment, the
`
`
`
`
`
`
`
`
`
`bus is a Direct Media Interface (DMI) bus that transfers data
`
`
`
`
`
`
`
`
`
`at high speeds in each direction between Northbridge 115 and
`
`
`
`
`
`
`Southbridge 135. In another embodiment, a Peripheral Com-
`
`
`
`
`
`
`
`
`ponent Interconnect (PCI) bus is used to connect the North-
`
`
`
`
`
`
`
`bridge and the Southbridge. Southbridge 135, also known as
`
`
`
`
`
`
`
`
`
`the I/O Controller Hub (ICH) is a chip that generally imple-
`
`
`
`
`
`
`
`
`
`ments capabilities that operate at slower speeds than the capa-
`
`
`
`
`
`
`
`bilities provided by the Northbridge. Southbridge 135 typi-
`
`
`
`
`
`
`
`
`cally provides various busses used to connect various
`
`
`
`
`
`
`
`
`
`components. These busses can include PCI and PCI Express
`
`
`
`
`
`
`
`busses, an ISA bus, a System Management Bus (SMBus or
`
`
`
`
`
`
`
`
`
`SMB), a Low Pin Count (LPC) bus. The LPC bus is often used
`
`
`
`
`
`
`
`to connect low-bandwidth devices, such as boot ROM 196
`
`
`
`
`
`
`
`
`
`and “legacy” I/O devices (using a “super I/O” chip). The
`
`
`
`
`
`
`
`
`
`“legacy” I/O devices (198) can include serial and parallel
`
`
`
`
`
`
`
`
`ports, keyboard, mouse, floppy disk controller. The LPC bus
`
`
`
`
`
`
`
`
`is also used to connect Southbridge 135 to Trusted Platform
`
`
`
`
`
`
`
`Module (TPM) 195. Other components often included in
`
`
`
`
`
`
`
`Southbridge 135 include a Direct Memory Access (DMA)
`
`
`
`
`
`
`controller, a Programmable Interrupt Controller (PIC), a stor-
`
`
`
`
`
`
`
`age device controller, which connects Southbridge 135 to
`
`
`
`
`
`
`
`
`nonvolatile storage device 300 such as a hybrid hard disk
`
`
`
`
`drive, using bus 184.
`
`
`
`
`
`
`
`[0024] ExpressCard 155 is a slot used to connect hot-plug-
`
`
`
`
`
`
`
`gable devices to the information handling system. Express-
`
`
`

`
`
`
`
`types of USB connected devices. While removable nonvola-
`
`
`
`
`
`
`
`tile storage device 145 is shown as a USB-connected device,
`
`
`
`
`
`
`
`removable nonvolatile storage device 145 could be connected
`
`
`
`
`
`
`
`using a different interface, such as a Firewire interface, etc.
`
`

`
`Southbridge 135 using Serial ATA (SATA) bus 188. Serial
`
`
`
`
`
`
`
`ATA adapters and devices communicate over a high-speed
`serial link. The Serial ATA bus is also used to connect South-
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`bridge 135 to other forms of storage devices, such as hard disk
`
`
`
`
`
`

`
`Ethernet controller 170 is connected to Southbridge 135
`
`
`
`
`
`
`
`
`
`using a bus, such as the PCI or PCI Express bus. Ethernet
`
`
`
`
`
`
`
`controller 170 is used to connect information handling system
`
`
`
`
`
`
`
`
`100 with a computer network, such as a Local Area Network
`
`
`
`
`
`
`
`
`
`(LAN), the Internet, and other public and private computer
`networks.
`
`
`
`
`
`
`
`
`
`[0026] While FIG. 1 shows one information handling sys-
`
`
`
`
`
`
`
`
`tem, an information handling system may take many forms.
`
`
`
`
`
`
`
`
`For example, an information handling system may take the
`
`
`
`
`
`
`
`form of a desktop, server, portable, laptop, notebook, or other
`
`
`
`
`
`
`
`form factor computer or data processing system. In addition,
`
`
`
`
`
`
`
`
`
`an information handling system may take other form factors
`
`
`
`
`
`
`
`such as a personal digital assistant (PDA), a gaming device,
`
`
`
`
`
`
`ATM machine, a portable telephone device, a communication
`
`
`
`
`
`
`
`
`device or other devices that include a processor and memory.

`
`
`[0027] The Trusted Platform Module (TPM 195) shown in
`
`
`
`
`
`
`
`FIG. 1 and described herein to provide security functions is
`
`
`
`
`
`
`
`but one example of a hardware security module (HSM).
`
`
`
`
`
`
`
`
`Therefore, the TPM described and claimed herein includes
`
`
`
`
`
`
`
`
`
`any type of HSM including, but not limited to, hardware
`
`
`
`
`
`
`
`security devices that conform to the Trusted Computing
`
`
`
`
`
`
`
`
`Groups (TCG) standard, and entitled “Trusted Platform Mod-
`
`
`
`
`
`
`
`
`ule (TPM) Specification Version 1.2.” The TPM is a hardware
`
`
`
`
`
`
`
`
`security sub system that may be incorporated into any number
`
`
`
`
`
`
`
`of information handling systems, such as those outlined in
`FIG. 2.
`
`
`
`
`
`
`
`
`FIG. 2 provides an extension of the information
`[0028]
`
`
`
`
`
`
`
`handling system environment shown in FIG. 1 to illustrate
`
`
`
`
`
`
`
`
`that the methods described herein can be performed on a wide
`
`
`
`
`
`
`variety of information handling systems which operate in a
`
`
`
`
`
`
`networked environment. Types of information handling sys-
`
`
`
`
`
`
`
`
`tems range from small handheld devices, such as handheld
`
`
`
`
`
`
`computer/mobile telephone 210 to large mainframe systems,
`
`
`
`
`
`
`such as mainframe computer 270. Examples of handheld
`
`
`
`
`
`
`
`
`computer 210 include personal digital assistants (PDAs), per-
`
`
`
`
`
`
`
`sonal entertainment devices, such as MP3 players, portable
`
`
`
`
`
`
`
`
`televisions, and compact disc players. Other examples of
`
`
`
`
`
`
`
`
`information handling systems include pen, or tablet, com-
`
`
`
`
`
`
`
`puter 220, laptop, or notebook, computer 230, workstation
`
`
`
`
`
`
`
`
`
`240, personal computer system 250, and server 260. Other
`
`
`
`
`
`
`
`
`types of information handling systems that are not individu-
`
`
`
`
`
`
`
`ally shown in FIG. 2 are represented by information handling
`
`
`

`
`
`system 280. As shown, the various information handling sys-
`
`
`
`
`
`
`
`
`tems can be networked together using computer network 200.
`
`
`
`
`
`
`
`Types of computer network that can be used to interconnect
`
`
`
`
`
`
`
`
`the various information handling systems include Local Area
`
`
`
`
`
`
`
`Networks (LANs), Wireless Local Area Networks (WLANs),

`
`
`include nonvolatile data stores, such as hard drives and/or
`
`
`
`
`
`
`nonvolatile memory. Some of the information handling sys-
`
`
`
`
`
`
`
`
`tems shown in FIG. 2 are depicted with separate nonvolatile
`
`
`
`
`
`
`
`
`
`data stores (server 260 is shown with nonvolatile data store
`
`
`
`
`

`
`
`store 275, and information handling system 280 is shown
`
`
`
`
`
`
`
`
`
`with nonvolatile data store 285). The nonvolatile data store
`
`
`
`
`
`
`
`can be a component that is external to the various information
`
`
`
`
`
`
`handling systems or can be internal to one of the information
`
`
`
`
`
`
`handling systems. In addition, removable nonvolatile storage
`
`
`
`
`
`
`
`
`device 145 can be shared amongst two or more information
`
`
`
`
`
`
`
`handling systems using various techniques, such as connect-
`
`
`
`
`
`
`
`
`ing the removable nonvolatile storage device 145 to a USB
`
`
`
`
`
`
`port or other connector of the information handling systems.
