Operating with Battery Power
Battery Calibration
Over time, as the battery is repeatedly drained and recharged,
battery performance will decrease. The first time you use the
battery, you should calibrate it. Occasionally, the battery needs
to be recalibrated for maximum performance. The calibration
process empties and charges the battery. This allows the Win-
dows battery gauge to accurately monitor battery status.
It is recommended you calibrate your battery:
The first time you use your computer
After it has been stored for awhile
If the gas gauge has become inaccurate.
Every three months for optimum performance
Windows XP Battery Calibration
To run the
Battery Calibration
program select
Start, All
Programs
, and
Mobile Computer Tools
. Next, select
Battery
Calibration
. After starting calibration, the
Battery Calibration
application requires no further input from the user. The calibra-
tion consists of four steps:
1.
P
artial
d
isCHarge
- the battery is drained to a level below 90
%.
2.
C
Harge
- the battery is fully charged to 100 %.
3.
d
isCHarge
and
CaliBrate
- First, the battery is discharged all
the way down to zero. Now the battery is ‘calibrated’ but not
charged. You may stop the process after this point and let the
battery charge outside of the Battery Calibration application.
4.
C
Harge
- if the Battery Calibration continues running, the bat-
tery will fully charge to 100%.
Battery Calibration will take from 5 to 10 hours, depending on
how much power the battery may already contain.
note
The unit will not go into suspend mode while Battery
Calibration is running.
Caution
Do not disconnect AC power while Battery Cali-
bration is running. If AC remains disconnected for more than
two minutes, the application will terminate.
Caution
Do not remove the battery while Battery Calibra-
tion is running. Doing so will cause the application to terminate
immediately.

Battery Charging
To charge the battery, install the battery pack and plug the AC
adapter into the computer and an electrical outlet. You can use
your computer while charging the battery. However, this will
increase the charging time.
note
We suggest that you charge the battery pack before
retiring for the day and let it charge overnight before traveling.
This ensures a fully charged battery for use the next day.
While the battery is charging, the Battery Power LED will be
active after 6-12 seconds and will stay lit until the battery is
fully charged. When the battery is fully charged, the Battery
Power LED will turn off.
If your computer is turned off, a fully discharged battery will
take about 3 hours to recharge. If your computer is turned on
and is not in suspend mode, it will take about 3-6 hours to
recharge the battery. Refer to the following table:
Charging
Discharging
System On

ing on tempera-
ture and processes

3.5 hours
System Off

7 days
note
A fully charged Li-Ion battery can run the Notebook for
approximately 3.5 hours of normal use. (According to an indus-
try standard bench marking tool). Use of external devices, the
optical disk drive and wireless radio causes increased battery
consumption. Refer to the
Battery Tips
section for ideas to
conserve battery power.
