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:
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.
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: Let the battery drain until your notebook automatically turns off.
