Installing a internal battery for the Nikon D70s

Do you mean the camera can't works well with your new Nikon D50 battery? But how about your original battery. Maybe your new battery is not so compatible with your camera so the camera can't recognizes the whole information on the Nikon D50 battery chips.

If the camera does respond when you hold down the shutter release, then the internal clock battery may have drained. As the manual says on page 17, charge your main battery, put it in the camera, and leave it be for up to three days.

the camera is provided with a battary charger,take out the battary from the camera put it in the given charger,charge it till u get green light,then try.

It's a US address, but they seem to accept international orders.

Have you tried formating the memory card? R07 means it has 7 shots in internal memory. Since you have already pressed the reset through the small hole in the front, if formatting the card does not work, try downloading the latest firmware from Nikon and installing it.

You can download a PDF version from the manufacturer's tech support site at http://support.nikontech.com/app/answers/detail/a_id/13948 . At least if you're willing to settle for an English-language one. If you want another language, you'll have to search through Nikon's international web site.

You can find them on ebay, and most of the electronic stores (Best Buy, Ckt City, etc.) sell a charger that will charge many different batteries. Just look for EN-EL3, which is the battery in the D70.

You would have to get an SDHC to CF adapter which could be pricey and they are hard to come by.

This camera allows at most a 4GB CF card, are you trying to use something larger, or does it do this with any size card? Also make sure card isnt write protected. Failing either of these suggestions, its possible that something has happened to the card slot internal to camera, they can be quite fragile.
