I've had my S30 for quite a while and lately i've had some problem with the slider opening up. Dont know if something got in between the slider and the cam or something. Anyway with some trouble i could still open up the slider and thus start up my cam but then one day when i was trying to close my cam i started to slide it to close. Finally it closed and i slided the slider onto the lens but then the lens started to open up again. But the slider was in the way so the lens opened up half way and then the camera beeped 3 times and the lens stopped. Now i can't get my camera to open or close because it is like halfway atm. I dont know what to do. Is there some kind of manual power button?
