The above table helps to define these SMBus Register values into 3 Levels. Once sort out the levels of these values, the
following table suggests action to be taken for abnormal situations:

Learning
Cycle count equal to zero suggested that the battery
has not been properly learned during the
production process. Although most of the latest
SMBus Gas Gauge IC has eliminated the
requirement for Learning as the initial RM and RSOC
are estimated using the open-circuit voltage (OCV)
characteristics of the programmed Li-ion chemistry.
However, battery capacity learning is still required in
order to find the accurate FCC, RM and RSOC.
Therefore, learning is suggested in order to reduce
problems when the battery is operated in the
Laptop.

Learning
Learning is suggested in order to gain more working
hours from the battery pack. The battery can still be
operated normally, however it represents the
battery should be replaced for its age and it can no
longer supports the normal usage of the laptop
operations.

Charge
The battery voltage has exceeded the safety
high/low limit, it is recommended to
Discharge/Charge the battery back to normal
operational voltage.
When the battery is too low and the Battery LED
light OFF, it is suggested to use waken charge to
recover the battery before any test.
