Calibrating the 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. 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.

To recalibrate the battery, complete the following steps:

1.Plug in the AC adapter.

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

3.After the Battery Charge 7 light turns off, unplug the AC adapter.

4.Turn on or restart your Notebook.

JTip Do not plug in the AC adapter during the process or you will have to start over with step 1.
