How to perform a calibration (full discharge)?
The most adequate method to do a full discharge (100% to a minimum of 3%) consists of the following procedure:
Fully charge the battery to its maximum capacity (100%);
Let the battery "rest" fully charged for 2 hours or more in order to cool down from the charging process. You may use the computer normally within this period;
Unplug the power cord and set the computer to hibernate automatically at 5% as described by the image sequence below (click images to enlarge). If you cannot select 5%, then you should use the minimum value allowed, but never below 5%;
Leave the computer discharging, non-stop, until it hibernates itself. You may use the computer normally within this period;
When the computer shuts down completely, let it stay in the hibernation state for 5 hours or even more;
Plug the computer to the A/C power to perform a full charge non-stop until its maximum capacity (100%). You may use the computer normally within this period.
