How to take out internal battery?

Hi, I'm going to give you a link to a basic user guide.

It's a small PDF file which has a diagram on the correct orientation of the SD card and batteries I think the actual owners manual is lacking in these diagrams.
I think though that you are attempting to install the memory card the incorrect way.

Also I'm going to include a great diagram for the SD card locking switch that if in the wrong position won't allow your to format a new card to the camera.

This should solve your problem don't forget to format your card to teh camera before using.

METAL PRONGS IN SD SLOT IN CAMERA WERE BENT

Sounds like the camera may need to be sent into canon to be fixed. I had to do that once- they allow you to track the camera from the moment they receive it- till the moment it is fixed. It was not so bad.

It is likely that an internal metal contact (one or several ones) inside the sdcard reader are bent, or damaged.

You will need to have your camera reviewed by a qualified technician to have it repaired, since it requires open the camera and evaluate the sd card reader mechanism.

Best regards,

The internal BIOS battery has run down and is causing this error. Don't attempt to fix this yourself. Canon will fix this for you for free, with free shipping, regardless of your camera's warranty status. See and print out the following advisory:

It may be fault with your memory card .

There is a chance that your memory card might have been corrupted

Also ensure that your battery is properly charged

There is also chance of mechanical problem existing in your camera .

Is your camera canon s3 or s5 or some other model

I get a memory card error everytime I insert a memory card. They are not locked and I have tried 4 different memory cards and nothing works. How can this problem be fixed?

On the old Powershot S400, this error was caused by a dead internal "clock" button battery. Fixing it required simply replacing the battery. But before you attempt to do that, would first suggest trying a different memory card.

There most definitely is a solution to this problem. Follow this link for a step by step fix for the memory card error. It requires taking the camera apart but if the warranty is expired you have nothing to lose. Fix worked fine for me.

Try a smaller memory card size . I was trying to install a 4gb card and the guy at Kmart told me to try a 1gb card and that fixed the locked card error . No where in the instruction book did it address this problem.
