You will need to write down your serial number.

I'm guessing its an Exilim EX-Z75

To record movies:
In REC mode, press the <BS> button (bottom right on back of camera)
Use the directions navigators to select the little camera icon on the menu. Press enter to select.
Press shutter button to start recording (A little REC symbol should come up in the monitor)
Press shutter again to stop recording when finished.
Give it a couple of seconds to recover between recordings (i.e. write the files).

Here's the manual - Page 82.

buy a new battery (DUH)

I think there was something wrong with the mainboard!

possibly with the usb cable but most likely you have to get the charger. http://www.amazon.com/Casio-Exilim-EX-Z75-Replacement-Battery/dp/B00125VCF4

Here is the charger, it is a bit expensive .
Here is a replacement price from Hong Kong , on Ebay, much cheaper, but I cannot guarantee the quality.

I called Parts Replacement at 1-800-223-2001 and they told me I would have to purchase the USB Cable for my casio exilim ex-z75 over the phone for $4 (part) + $4.95 (S&H) because it not sold ANYWHERE online. I was hoping to get a cheap cable for a few bucks, but this is better than nothing!

what operating system ????
