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

• 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

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.
