Laptop Battery Introduction

If a laptop is stored for an extended period of time with the battery present in the system, the battery may not charge as expected when?AC power is applied. The systems battery indicator LED may signal a fast flashing 4 Amber, followed by single steady Blue (or Green depending on the system)?pattern (Figure 1), repeating, which signifies a ¡®Temporary failure¡¯ of the apple a1185  battery? On older systems, the system battery indicator LED may not illuminate, and it just does not charge the battery.?

The cells within the battery packs are trickle discharging, where the firmware of the battery pack still think it is fully charged. The cells eventually reach a level of close to zero charge, and the apple macbook pro 13 inch battery’s firmware is still thinking it is fully charged.?When powered on with the system, it performs an integrity check and takes the assumption of a ¡®bad¡¯ battery pack, as there is a mismatch between the indicated power level and the actual cell charge.

Solution:
The following procedure may recover the battery pack:

1.Physically remove the battery pack from the system and leave it out for 1 minute, which allows sufficient time for the Dell Vostro 1310 battery  firmware to resynchronize with the actual cell charge state.
2.Insert the battery into the system at this point, and leave it on charge for an extended period of time. Approximately 12 hours will be sufficient to recover the battery pack to its peak performance.
