[Alarms] - [Alarm Action]:

B. Set the value for [Critical battery alarm] to 5% or more.
This is necessary for the standby or hibernation function to be completed
(assuring data is saved) when the battery level is low.
The battery pack has a function for measuring, storing and learning about battery capacity.
Using this function properly to accurately display remaining battery capacity requires 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.
NOTE
z If the computer is turned off while recalibrating the battery (electrical power outage,
accidental removal of the AC adaptor or battery pack, etc.), the battery will not be
recalibrated correctly.
z Battery Recalibration does not increase the battery's capacity. If Battery Recalibration
is executed frequently, deterioration of the battery may result.
z Perform the following procedure in a temperature range of 10°C to 30°C {50°F to
86°F}.
1 Attach the battery pack, then connect the AC adaptor.
Remove all peripherals (except for the battery pack and AC adaptor).
