recalibrating your battery
We recommend recalibrating your battery several times a year, or more often if
you frequently use your battery. If your battery charge icon or the power meter
becomes inaccurate, you need to recalibrate your battery.
To recalibrate your battery:
1. Close all open files and programs.
2. Connect your notebook to AC power and allow the battery to completely
charge.
3. After the battery is completely charged, disconnect the AC adapter and
either turn on or restart your notebook.
4. Completely discharge the battery by doing the following:
a. From your desktop, click Start > Control Panel > Performance and
Maintenance > Power Options.
b. On the Power Schemes tab, select the Always On power scheme.
c. On the Alarms tab, deselect the check boxes for the Low battery alarm
and the Critical battery alarm.
Important: Do not use your notebook during the calibration
process.
Do not connect the AC adapter to your notebook during
this process, or you will interrupt the calibration process and
will have to start again.
Important: Let the battery drain until your notebook
automatically turns off.
