I have a Sony Cyber-Shot DSC-W80. I left it in my backpack over the Thanksgiving weekend because I was going to charge the battery and coping some pictures to my computer. I ended up forgetting about it, and when I pulled it out the next Monday, the lens was sticking out, and the shutter was open. The battery was dead, so I couldn't get it to close back up. I charged the battery and then turned the camera on and off again, and it closed properly. Now I hear a louder sound than usual whenever the lens comes out or goes back in. It seems to take pictures okay, but I just want to be sure nothing's wrong.
