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.
