检查了包装及配件无误。按照说明书插上充电器给电池充电，但没有任何反应。充了一个小时，信号灯也不亮。我的另一款老型号的Motorola手机插上充电器信号灯就亮，显示正在充电。难道这一款有什么特殊步骤要做，请有经验的朋友指教。谢谢！
充电说明如下：
To charge using the charger:
1 Insert the charger into the USB connector on your phone as shown.
2 Plug the other end of the charger into the appropriate electrical
outlet.
The battery indicator N flashes while your phone is charging.
3 When your phone indicates Charge Complete and the battery indicator stops flashing, remove the charger.
Tip:
You can safely leave the charger connected to the phone after charging is
complete. This will not damage the battery.
When you charge the battery, the battery level indicator in the upper right corner of the display shows how much of the charging process is complete. At least one segment of the battery level indicator must be visible to ensure full phone functionality while charging.
