Important Battery Tips
The battery pack has a function for measuring, storing, and learning about battery capacity. Using “Battery Recalibration”
function properly to accurately display remaining battery capacity requires that the battery 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 procedure described below should be performed again.
1
Connect the AC adaptor.
2
Close all applications.
3
Perform "Battery Recalibration".
A
Select [Start] - [All Programs] - [Panasonic] - [Battery Recalibration].
B
At the confirmation message, select [Start].
z
Performing "Battery Recalibration" at frequent intervals degrades the battery. A message urging caution will
appear when "Battery Recalibration" is to be performed again in less than a month or so since it was last
performed. In a case like this, do not perform "Battery Recalibration."
C
The display will ask you to shut down Windows. Select [Yes].
"Battery Recalibration" will begin.
After the battery pack is fully charged, discharging begins. When the discharging is completed, the power
automatically goes off.
When "Battery Recalibration" is completed, charging begins.
