The battery does not charge

To prevent possible damage to the battery, the system will not allow a charge if the battery
temperature is extremely hot or cold (such as in a closed, unattended vehicle). If possible, charge
the battery in a location with a moderate temperature of around 20°C (68°F).

If possible, turn off the computer while the battery is charging.

If the battery is new or has been stored for a week or more, follow this procedure:
1. Make sure the computer is turned off.
2. Open the battery door and remove the battery.
3. Connect the AC adapter
to the computer and an AC wall outlet, and then turn on the computer by
pressing the
Power Button

4. Let the computer complete the boot process. Then reinstall the battery and replace the battery
door..
5. Allow the system to remain idle for one hour with the AC adapter connected to the computer.

6. If the battery still fails to charge after an hour, remove the battery, wait several seconds, and then
installitagain.

The batteries take much longer than seven hours to charge

Under moderate temperatures, about 21°C (70ºF), the computer’s battery takes approximately 4 to
5 hours to completely charge. Under extremely cold or hot temperatures, however, the battery can
take up to 16 hours to fully charge.
The batteries don’t last very long

Calibrate the battery using the Battery Calibration selection in Mobile Computer Tools. If your
battery is new or has not been used for several weeks, calibrating the battery over a weekend may
substantially increase its capacity.

As your battery ages, the maximum capacity that it can hold naturally decreases, and even the best
maintained batteries eventually need to be retired. Consider replacing the battery if you are not
getting the usage you need from it.
The gas gauge isn’t full after charging the battery

This may indicate that the charging process terminated prematurely.
