The battery pack has a function for measuring, storing and learning about battery ca-
pacity. Using this function properly to accurately display remaining battery capacity re-
quires that the battery pack be fully charged (charged to 100%), then fully discharged,
and then fully charged again.
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
Attach the battery pack and connect the AC adaptor
Remove all peripherals (except for the battery pack and AC adaptor).
2
Use the “Refresh Battery” utility to fully discharge the battery
pack
1 Run the Setup Utility. ( page 36 )
2 Select [Refresh Battery] from [Exit] menu, then press Enter .
3 At the confirmation message, select [Yes], then press Enter .
The battery pack will be completely charged and discharged, the computer will
power off automatically, and then charging will commence. It takes approximately
3 hours until the power automatically goes off through the complete discharge of
the battery from the fully charged state.
3
Allow the battery pack to charge until the battery indicator turns
green
Charging Time: Approximately 3 hours.
