An embodiment includes a power management method for regulating power to a handheld computer. A source voltage is received from a battery module. The source voltage is regulated to power a plurality of internal components, including a processor and a memory. If the source voltage is detected to be less than a designated threshold, the plurality of internal components powered by the source voltage are reduced to allow a charge of the battery module to increase in absence of an external charge.

Method and apparatus allowing a battery to regain charge in a handheld device without an applied external charge while still supplying power selected designated components

A method for software control using a user-interactive display screen feature is disclosed that reduces stylus or other manipulations necessary to invoke software functionality from the display screen. According to the method, a graphical feature having a surface area is displayed on a touch-sensitive screen. The touch-sensitive screen is coupled to at least one processor and the graphical feature is generated by an operating system and uniquely associated with a particular software program by the operating system. To control software executing on the processor, a user-supplied writing on the surface area is received and the software is controlled responsive to the writing. In alternate embodiments, the method further controls data stored in a memory device responsive to the writing or further controls transmission of data from a radiation emitter, which may be coupled to voice and data networks.

Method for controlling a handheld computer by entering commands onto a displayed feature of the handheld computer

A handheld computer comprises a rechargeable battery module that outputs a source voltage to power one or more components of the handheld computer. The handheld computer includes a power monitoring module that receives the source voltage and outputs a rail voltage. The power monitoring module outputs the rail voltage to correspond to a fractional duty cycle of the source voltage when the source voltage is greater than a designated voltage. The power monitoring module outputs the rail voltage to correspond to a full duty cycle of the source voltage when the source voltage is less than the designated voltage. The handheld computer includes a power rail coupled to the power monitoring module. The power rail receives the rail voltage so as to extend power from the battery module to the one or more components of the handheld computer.

Method and apparatus for allowing a battery to preserve charge in a handheld device without an supplying unregulated voltage to selected internal components

Embodiments of the invention include connector assembly for a handheld computer. The connector assembly includes a plurality of conductive elements disposed on a first side of a printed circuit board housed with the handheld computer. One or more of the conductive elements has a pointed end.
