Abstract: Embodiments of this invention provide for a versatile connector that is capable of receiving any one of two types of connectors. The connector is preferably positioned on a bottom edge of a handheld computer to receive either pogo style or wiping style connectors. As a result, the connector enables the handheld computer to connect with accessory devices that use either style connectors. In particular, the handheld computer can connect with communication cradles using wiping style connectors, or smaller accessory devices that use pogo style connectors.

Abstract: Embodiments of this invention provide for detecting a type of an accessory device connected to a portable computer. The portable computer may detect a signal from the accessory device and determine the type of accessory device using the signal. Once the type of accessory is identified, the portable computer may implement a software that matches the particular type of accessory. The type of accessory may be identified by measuring a voltage of a signal line that is coupled to the accessory device. The value of the voltage on the signal line may then be matched to a corresponding accessory type using a memory of the portable computer.

Abstract: Methods and apparatus are described for providing a time-based warning indicating that the energy capacity of a primary energy source of a battery-powered computer has discharged to a low level, and using residual energy of the primary energy source to perform at least one pre-cutoff function. The time-based warning ensures that the warning is provided in a timely manner by overcoming problems caused by analog to digital converter voltage measurement accuracy limitations and flat battery operating voltage versus discharge curves. The battery (110) provides power to operate the computer until the battery voltage discharges to the cutoff voltage (350). The methods and apparatus provide advantages because they reserve the residual energy in the battery (110) to perform at least one pre-cutoff function within a first duration before the battery (110) discharges to the cutoff voltage (350). Some embodiments of the invention include hardware resources coupled with the processor (120) to lock out power and application activation when the rechargeable battery (110) has discharged to a predetermined hardware lockout voltage (340).

Abstract translation: 描述了用于提供基于时间的警告的方法和装置，其指示电池供电的计算机的主要能量源的能量容量已经排放到低水平，并且使用主能量源的剩余能量来执行至少一个预 -ctoto功能。 基于时间的警告确保通过克服模数转换器电压测量精度限制和扁平电池工作电压与放电曲线引起的问题及时提供警告。 电池（110）提供电力来操作计算机直到电池电压放电到截止电压（350）。 所述方法和装置提供了优点，因为它们在电池（110）放电到截止电压（350）之前的第一持续时间内保留电池（110）中的剩余能量以执行至少一个预切断功能。 本发明的一些实施例包括与处理器（120）耦合以在可再充电电池（110）已经放电到预定的硬件锁定电压（340）时锁定电力和应用激活的硬件资源。
