Thanks for that Idea..I left it now connected with USB..Is that sufficient to charge the battery rather than connecting it to the power outlet? The only difference I would say between these two connectivity to charge the battery is - when connected to the power outlet, the NOKIA comes with the backlight and then reboots continuously..but when connected to the USB, the back-light is absent...all it happens here is the orange led glows for some time and then the NOKIA logo with no backlight..this process is continuing now..does it harm the device anyway?
