Tip
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 glows green, showing that the battery is fully
charged.
b. After the battery charge light or the icon glows green,
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 Options
icon on the
Control Panel
.
The Power Options Properties dialog box opens.
