Accurately Displaying Battery Capacity (Battery Recalibration)
The battery pack has a function for measuring, storing and learning about battery capacity.
Using the Battery Recalibration function to accurately display remaining battery capacity
requires that the battery pack be fully charged (charged to 100%), then fully discharged. This
procedure should be performed once after you purchase the computer. As you use the
battery pack over a long period of time, the remaining capacity display may become
inaccurate due to aging of the battery pack and other factors. The following procedure
should be performed again.
NOTE
Perform the following procedure in a temperature range of 10
If the computer is turned off while performing the "Battery Recalibration" (electrical
power outage, accidental removal of the AC adaptor or battery pack, etc.), the
"Battery Recalibration" will not be performed properly.
The "Battery Recalibration" function takes time to execute because of the large
battery capacity; this is not a malfunction.
• Time taken to obtain a full charge: Approx. 5 hours [max.]
• Time taken for a complete discharge: Approx. 4.5 hours
"Battery Recalibration" does not increase the battery's capacity. If "Battery
Recalibration" is executed frequently, deterioration of the battery may result.
If you have two or more battery packs, perform the "Battery Recalibration" for each
battery pack.
