When the battery reaches the normal temperature level, it begins
to charge until charging is complete.
A fully discharged battery pack charges in several hours. Charge
time depends on the amount of power being used by the computer.
Ensuring Battery Gauge Accuracy
The battery gauge built into your computer displays the amount of
charge remaining and is precalibrated for accuracy (To access the
battery gauge, press the
Fn+F8 hotkeys). To ensure continued
battery gauge accuracy and to maximize battery operating time
■ Fully charge a battery pack prior to the first time that you use
it with the computer.
■ Allow the battery pack to completely charge before removing
external power from the computer, optional desktop expansion
base, convenience base, or battery charger.
Calibrating a Battery Pack
If your battery charge display seems inaccurate, you may need to
recalibrate your battery pack. This may take several hours, so a
good time to do this is overnight. The calibration utility supports
both the primary and MultiBay battery packs. Check the
calibration status of your batteries by accessing the Battery
Calibration tab:
■ In Windows 95 select StartÅSettingsÅControl
PanelÅPowerÅBattery Calibration tab.
■ In Windows NT 4.0 select StartÅSettingsÅControl
PanelÅCompaq PowerÅBattery Calibration tab.
■ In Windows 98 select StartÅSettingsÅControl
PanelÅPower ManagementÅBattery Calibration tab.
View the battery calibration reports in the Status column. A
battery pack can only be calibrated if the Status column beside a
battery pack reports “Needs Calibration.”
The Battery Calibration utility calibrates one battery pack at a time
by fully discharging it, then fully recharging it. It can run in the
background as you use the computer.
