Calibration

All batteries lose their charge if they have not been used for a long period of time. In this section of “Caring for Your Battery” you will become familiar with the following:

•Calibrating the Battery

•Maximizing Battery Operating Time

•Fixing a Low-Battery Condition

Calibrating the Battery

You may notice that the battery gauge does not correctly display the battery charge level when you first receive your Notebook, or if you have not used your Notebook for a long period of time. If the battery gauge becomes inaccurate, you must recalibrate your battery. Recalibrating the battery simply means recharging the battery to its maximum capacity and resetting the battery gauge to display the level of charge accurately.

To recalibrate the battery, complete the following steps:

1.Plug in the AC adapter:

a.Allow the battery to charge until the Battery Charge 7 icon turns off, showing that the battery is fully charged.

b.After the battery charge light or the icon turns off, unplug the AC adapter.

2.Turn on or restart your Notebook.

Steps 3 through 6 prevent your Notebook from entering Sleep mode. These steps also allow the battery to drain faster.

3.On the Windows taskbar, click Start, point to Settings, and then click Control Panel.

4.Double-click the Power Management : icon on the Control Panel. The Power Management Properties dialog box opens.
