Zusammenfassung:	An electronic device (100) is configured with sub-assemblies including a main logic board ( 405), flexible printed circuit ( 410), and dual battery packs ( 415, 420) that are assembled together with electrical connectors ( 490, 480, 485) to enable power from the battery packs to flow over a power bus ( 402) that is distributed along the flexible printed circuit and main logic board. A protection circuit module (PCM) in each battery pack (435, 440) is configured to determine a state of each of the connections among the sub-assemblies (i.e., whether or not properly assembled to provide electrical continuity through the connector) so that power from the battery packs is switched on to the power bus only when electrical continuity is verified at each of the connectors. In the event that any connection is faulty, for example due to a misalignment of a connector during assembly that prevents electrical continuity to be established through a connector, neither PCM will switch power on to the power bus.
