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.

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