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.
1Attach the battery pack, then 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 47)
2 Select [Refresh Battery] from [Exit] menu and press Enter .
3 At the confirmation message, select [Yes] and press Enter . Once the battery
indicator turns green, the battery pack will be completely discharged. It takes
approximately 3 hours until the power automatically goes off through the com-
plete 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.
