Autofocus is no more working.

Hello mohd, This is a known bug with some digital cameras. The firmware gets corrupted and doesn't "remember" the position of the lens when it is forced to shut down because of not enought battery power. When you power the camera back on, it will relly on the latest settings for the lens, and since they were corrupted when the power was cut off suddenly, these kind of problems can occur. In order to fix this you will need to have the camera's firmware rewritten. Because your camera is new, I sugest you go to the shop where you bought it and ask for an in waranty repair. Don't try to write the firmware yourself because you may loose the waranty. However before sending it to a service, you can try to reset the camera. If your model doesn't have a reset swich or nothing is told about this in the user manual, you may reset it by removing battery and then pressing the power button for 2 min (keep it pressed). Then release it and press every button on the camera twice (including zoom buttons, shutter, menu knobs ..everything). Then reconect the battery and try to power it back again. If you need more info please post back. Good luck.
