Battery Calibration
The battery calibration process fully charges, discharges, and
recharges the battery. This allows the Windows® battery gas
gauge to accurately monitor battery status.
It is recommended you calibrate your battery:
The first time you use it
After it has been stored for awhile
If the gas gauge has become inaccurate.
For optimum performance, we recommend calibrating the bat-
tery and optional secondary battery every three months
You can calibrate your main battery or optional second exter-
nal battery from the BIOS Setup Utility. You can also calibrate
the main battery from within Windows®.

To run the Battery Calibration program
from Windows®, select Start, Programs, and Mobile Com-
puter Tools.
After starting calibration, the Battery Calibration application
requires no further input from the user. The calibration consists
of four steps:
1.
Partial Discharge.
2.
Charge: The battery is fully charged to 100 %.
3.
Discharge and calibrate: First, the battery is discharged all
the way down to zero. Then 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.
Charge: If the battery calibration continues running, the battery
will fully charged to 100%.
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.
