A method and apparatus for mission critical standby of a portable communication device are disclosed. A portable communication device may include a primary processor for a first operating platform, a secondary processor for a second operating platform and communicatively coupled to the primary processor, and a power state manager that may have a first mode and a second mode. The power state manager may be configured to determine whether the primary processor is in a powered off state and sequence supply of power to the secondary processor. The first mode may allow the primary processor to monitor a power state of the secondary processor based on a determination that the primary processor is not in the powered off state and the second mode may enable the power state manager to monitor the power state based on a determination that the primary processor is in the powered off state.

A portable communication device is provided with a power arbitration module formed with hardware logic configured to detect attachment of a battery and determine whether the battery is one of: an intrinsically safe (IS) battery or a standard, non-intrinsically safe (non-IS) battery. The power arbitration module enables a converged platform mode of operation in response to determining that the battery is a standard, non-intrinsically safe battery. The power arbitration module enables a land mobile radio (LMR) mode of operation in response to determining that the battery is an intrinsically safe battery. The determination of the battery type and enablement of operating mode is handled by hardware logic of the power arbitration module without use of a software protocol.
