My daughter has the Casio Exilim EX-Z90 and when switching on the lens only comes out so far then goes back in and switches off. The battery is fully charged.

I will not further review this camera since many have given fine reviews here. My goal of this review is to explain a fix to a problem I had with this camera. Upon a search, I learned that others had similar problems but could not locate a good answer or fix.

THE PROBLEM: Casio Exilim EX-Z90 turns off suddenly after being turned on AND/OR the camera will NOT stay on after the power is pressed.

THE FIX: I was completely at a loss for this problem. I searched Casio's site, I e-mailed their customer service, and searched the internet for a fix and found NO HELP. One day my child told me that if they pressed against the bottom of the battery enclosure that the camera stayed on. I began to explore what this could mean. It was soon obvious to me that the three copper nubs that the battery sets against in the camera must have been pressed down too far. My child had a difficult battery one day and pressed very hard to get it out. This must have depressed the copper connectors (nubs) to where they did not make good contact with the battery causing the momentary power up and then quick shut down.

I had a pair of tweezers that allowed me to gently pull the copper connectors back up slightly thus allowing the battery to have proper contact. Once this was accomplished, the camera powered up and stayed on with no issues. You must be careful so as not to break the copper connectors off because if you do, the camera is done.

Why Casio does not have this printed as a troubleshooting option is beyond me. I hope this helps others out there.

Good luck!!
