How to calibrate the battery of a notebook?

[Xylina]

Hi friends,
I want to know about the calibrating the battery of the notebooks. Now I am using the Windows XP as operating system and will upgrade to Windows 7 soon. So provide an information accordingly. Since, I don't know much about the calibration of batteries, I am requesting you to give some detailed information. Please explain me how to calibrate the battery of a notebook? Hope that someone over there would help me faster.!!

Calibrating the battery recharged means full capacity and adjust the indicator to show battery charge level accurately. The battery meter in the Windows system tray may not indicate the battery charge properly when the laptop is new or has not been used for a long time. If the battery meter becomes inaccurate, use some methods to calibrate the measurement of the battery.

A calibration cycle requires that the battery is fully charged and then fully discharged. During the calibration cycle, the properties can be turned off power management to allow the battery to discharge completely. You will have to keep this in mind. Without discharging the batteries, you can do the calibrating of your battery but that won't be much worthy. So I would like to suggest you to let the battery discharge completely and then you can carry on with your process.
