Before using the battery pack for the first time, the battery pack
should be calibrated in order to get accurate reporting of remaining
battery life status.
To calibrate the battery pack follows the instructions below:
1.
Insert the battery into the battery compartment and turn on the
notebook. If the battery is completely without power go to the
next step. Otherwise, let the battery run down until the
battery low-low warning beeps are heard. The system will
automatically enter Suspend mode.
2.
Turn the notebook off. Connect the AC adapter and let the
battery fully recharge. When the battery charge indicator
turns off, the battery is fully charged.
3.
Turn On the notebook, let the battery run down until the
battery is in low-low state and you hear a warning beeps.
The system will automatically enter the Suspend mode. You
can now connect the AC adapter.
4.
The battery pack is now calibrated properly.
In general, using the battery until the low-low battery-warning
indicator appears and fully recharges the battery each time (full
discharge/charge cycle) will ensure the accurate reporting of the
battery gauge status.
