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 repeated.
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 39)
2 Select [Refresh Battery] from the [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 dis-
charged. It takes approximately 2 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
