Battery

Calibration

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

•Calibrating the Battery

•Maximising Battery Operating Time

•Fixing a Low-Battery Condition

Do not plug in the AC adapter while the battery is draining or you will have to begin again at step 1.

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. Re- calibrating 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 light above the Battery Charge 7 icon turns off, indicating that the battery is fully charged.

b.After the battery charge light 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.
