Why can't I power my PDA after I plug in the charger?

This can occur for three reasons

1) Please check that the insulating tape is not removed from the battery

2) There is something wrong with the charging power cord.

Tips: We recommend that you use a combination of the original charging cable and charging head.

3) Battery is faulty: Verify that other batteries charge properly. If not, replace the faulty battery.

Extreme battery temperature: Battery does not charge if the ambient temperature is below 5°C (41°F) or above 40°C (104°F).
