My son has a sony mavica mvc-fd81 digital camera. i ordered a charger and high capacity battery for it online it came in today and he was disappointed cause it would no fit in it. it looks like it would work if the cover was off but i dont want tobreak the cover for it do i need to order a small one or will this install?

SOURCE: my sony mavica mvc-fd81 turns on for only seconds,and turns off.

Have you tried another battery?
Even the lithium ions will eventually not hold a re-charge.
If the unit stays on with external power, there is a good possibility that a new battery will solve the issue

SOURCE: Lost my program disc for my camera. Where can I

this is what you do, you go on google and type in the name of your camera and then type in program disk download, then you should get something that will help
