摘要:
A battery type detection approach is disclosed. In one embodiment, a method of detecting a battery type can include: receiving a signal from a battery module in a portable computing device; determining if the signal is in a first state for at least a first predetermined time before transitioning to a second state; determining if the signal transitions from the second state to the first state after a second predetermined time, and identifying the battery type in response thereto; and asserting an indication of the battery type when a third predetermined time period after the transition from the second state to the first state has occurred.
