     FIELD 
     The present invention generally relates to portable computing devices, and more particularly, to portable computing device docking stations. 
     DESCRIPTION OF THE RELATED ART 
     Portable computing devices (PCDs) are ubiquitous. These devices may include cellular telephones, portable digital assistants (PDAs), portable game consoles, palmtop computers, and other portable electronic devices. As technology increases, PCDs are becoming increasingly powerful and rival laptop computers and desktop computers in computing power and storage capabilities. 
     One drawback to using a PCD, however, is the small form factor typically associated therewith. As the PCD gets smaller and is made more easily portable, using the PCD may become increasingly difficult. Further, the small form factor of a PCD may limit the amount of ports, or connections, that may be incorporated in the shell, or housing, of the PCD. As such, even as PCDs become more powerful and have increased capabilities, access to the power and capabilities may be limited by the sizes of the PCDs. 
     Accordingly, what is needed is an improved for system and method for taking advantage of the computing capabilities provided by a PCD.

     Referring to  FIG. 33 , a method of managing power distribution between a PCD and a PCD docking station is shown and is generally designated  3300 . Commencing at block  3301 , a do loop may be entered in which when the PCD is docked with the PCD docking station, the following steps may be performed. At decision  3302 , a power management module may determine whether the PCD is powered on. If so, the method may proceed to block  3303  and the PCD docking station may be turned on, e.g., by the power management module. Otherwise, the method may proceed to block  3304  and the PCD and the PCD docking station may be turned on, e.g., by the power management module. From block  3303  and block  3304 , the method may proceed to block  3305 . 
     At block  3305 , the power supply to the PCD may be switched from the PCD battery to the PCD docking station battery. At block  3306 , the PCD docking station and the PCD may be powered from the PCD docking station battery. Further, at block  3308 , the PCD battery power may be determined, e.g., the remaining battery power of the PCD battery may be determined. 
     Moving to decision  3310 , a power management module may determine whether the PCD battery power is equal to a charge condition. For example, the power management module may determine whether a remaining battery life is below a predetermined value, e.g., a percentage (%) of total PCD battery life. Also, the power management module may reside in a processor within the PCD. 
     Returning to the description of the method  3300 , if the PCD battery power is equal to a charge condition, the method  3300  may proceed to block  3312  and the PCD battery may be charged from the PCD docking station battery. Thereafter, the method may continue to block  3314 . Returning to decision  3310 , if the PCD battery power is not equal to the charge condition, the method may move directly to block  3314 . 
     At block  3314 , the PCD docking station battery power may be monitored. Next, at decision  3316 , the power management module may determine whether the docking station battery power is equal to a warning condition. For example, the power management module may determine whether a remaining battery power associated with the PCD docking station battery is below a predetermined value, e.g., a percentage (%) of total PCD docking station battery life. 
     If the docking station battery power is not equal to the warning condition, the method may return to block  3314  and continue as described herein. Otherwise, if the docking station battery power is equal to the warning condition, the method  3300  may move to block  3318  and the power management module may transmit a first warning to the user. The first warning may be an audio warning, a visual warning, or a combination thereof. From block  3318 , the method  3300  may move to block  3320  of  FIG. 34 . 
     At block  3320 , the power management module may monitor the PCD docking station battery power. Then, the method may move to decision  3322  and the power management module may determine whether the docking station battery power is equal to a critical condition. For example, the power management module may determine whether a remaining battery power associated with the PCD docking station battery is below a predetermined value, e.g., a percentage (%) of total PCD docking station battery life. If the PCD docking station battery power is not equal to the critical condition, the method  3300  may return to block  3320  and continue as described herein. Otherwise, if the PCD docking station battery power is equal to the critical condition, the method  3300  may proceed to block  3324  and the power management module may transmit a second warning to the user. The second warning may be an audio warning, a visual warning, or a combination thereof. 
     From block  3324 , the method may continue to decision  3326  and the power management module may determine whether a power source is plugged into the PCD docking station. The power source may be an alternating current (A/C) power source, an external direct current (D/C) power source, or a combination thereof. If a power source is plugged into the PCD docking station, the method  3300  may continue to block  3328  and the power management module may charge the PCD docking station battery from the power source. Thereafter, the method may return to block  3305  of  FIG. 33  and continue as described herein. 
     Returning to decision  3326 , if the power management module does not detect that a power source is plugged into the PCD docking station, the method  3300  may proceed to block  3330  and the power management module may switch the power supply to the PCD and the PCD docking station from the PCD docking station battery to the PCD battery. Next, at block  3332 , the PCD docking station and the PCD may be powered from the PCD battery. 
     Moving to block  3334 , the power management module may monitor the PCD battery power. At decision  3336 , the power management module may determine whether the PCD battery power is equal to a power down condition. For example, the power management module may determine whether a remaining battery power associated with the PCD battery is below a predetermined value, e.g., a percentage (%) of total PCD battery life. If the PCD battery power is not equal to the power down condition, the method  3300  may return to block  3334  and continue as described herein. Conversely, if the PCD battery power is equal to the power down condition, the method  3300  may continue to block  3338  and the power management module may turn off the PCD/PCD docking station combination module. Then, the method  3300  may end. 
     With the configuration described herein, the PCD/PCD docking station combination provides feature segmentation between the PCD and the PCD docking station. A PCD may be engaged with a PCD docking station in one of the manners described herein. For example, a PCD may be engaged with a PCD engagement mechanism, e.g., a PCD docking pocket, a PCD docking tray, or a similar mechanism. Further, dual display usage is provided, e.g., by a display in a PCD and a display in a PCD docking station. When engaged with a PCD docking station, a PCD may be charged by the PCD docking station. Moreover, seamless user interface and application transition may be provided as the PCD is docked or undocked. 
     In a particular aspect, user interface features may be provided when a PCD is docked or undocked. One such aspect, is a “fish-eye” bubble that may be provided across all applications displayed on the PCD. Additionally, application layer scaling may be provided. For example, a primary application version may be executed when a PCD is docked and a secondary application version may be executed when a PCD is undocked. Alternatively, a standard application version may be executed when a PCD is undocked and an enhanced application version may be executed when a PCD is docked. In an undocked mode, a PCD may execute less computational intensive, smaller footprint applications. In a docked mode, full functionality applications may be executed by the PCD. Whether a PCD is docked or undocked may be automatically detected and the appropriate application versions may be executed when available. 
     When a PCD is undocked, two low power processors may be used for small screen applications and the PCD operating system (OS). Further, two high performance processors may be used to execute larger applications when the PCD is docked with a PCD docking station. In another aspect, when the PCD is docked, one processor may be used for mouse controls and graphical user interface controls, i.e., touch screen controls; one processor may be used for shared input/output controls; one processor be used for a PCD OS; and one processor may be used for a desktop OS stored on a PCD docking station. In yet another aspect, each processor may run a different OS and framework. 
     A PCD docking station may be connected to a home network and when a PCD is docked with the PCD docking station, the PCD may, in turn, be connected to the home network. Moreover, data, e.g., applications, content, or a combination thereof, may be automatically backed up to a PCD docking station when a PCD is docked with the PCD docking station. A PCD docking station may include a display, a display buffer, a HDD, additional memory, LAN capabilities, WLAN capabilities, one or more USB ports, printer connections, a keyboard, a mouse, etc. The PCD docking station may include a large screen application memory. A large screen application and an OS state may be retained in the PCD docking station memory when the PCD is undocked in order to enable instant-on when the PCD is again docked. A large screen application may include a browser application, a word processor application, a spreadsheet application, a presentation application, an email application, a calendar application, a video application, or a combination thereof. A small screen application may include a media player application, a phone application, a control application, or a combination thereof. 
     When a PCD is docked with a PCD docking station, a user can take advantage of a relatively larger display incorporated into the PCD docking station. Further, a user may use a full keyboard and mouse to access data stored in the PCD. A PCD docking station may be incorporated into a vehicle, a kiosk, a set top box, etc. and a PCD may be docked therewith. 
     It is to be understood that the method steps described herein need not necessarily be performed in the order as described. Further, words such as “thereafter,” “then,” “next,” etc. are not intended to limit the order of the steps. These words are simply used to guide the reader through the description of the method steps. 
     In one or more exemplary aspects, the functions described may be implemented in hardware, software, firmware, or any combination thereof. If implemented in software, the functions may be stored on or transmitted over as one or more instructions or code on a computer-readable medium. Computer-readable media includes both computer storage media and communication media including any medium that facilitates transfer of a computer program from one place to another. A storage media may be any available media that may be accessed by a computer.
