Portable computer battery recovery and reconditioning mechanism
First Claim
1. In an information handling system, a method for recovering a smart battery, the battery providing energy to at least one component of the information handling system, the method comprising:
- providing a battery that provides power to an electronics unit that is operable to control an operating condition of the battery;
determining that the electronics unit is inoperable;
in response to determining that the electronics unit is inoperable, providing a charge to the battery through a first charge path that bypasses the electronics unit, wherein the charge provided to the battery is sufficient to charge the battery such that the electronics unit becomes operable;
detecting that the electronics unit has become operable; and
in response to detecting that the electronics unit has become operable, disabling the first charge path and providing a charge to the battery through a second charge path.

Abstract
For recovering and reconditioning a smart battery, a functionally dead condition of the battery is detected. The battery includes an electronics unit. The electronics unit is operable for controlling an operating condition of the battery. In the functionally dead condition of the battery, the electronics unit becomes inoperable. While in this condition, a current limited trickle charge is provided to the battery such that the path of the trickle charge bypasses the inoperable electronics unit. Upon the battery receiving a sufficient amount of charge, the electronics unit regains control. The electronics unit reconditions the battery by recharging it to a fully charged state.
