Do you have more than one battery?

How old is the battery?

Is it a genuine Canon battery or 3rd party battery?

Have you checked the battery status (

Both the 5D III and the 7D have the ability to monitor battery status. You might want to compare them.

If it's an old battery, it's possible that it's warning you that while it may be "fully" charged, the full charge capacity of an old battery isn't very good -- and it's just alerting you to that.

Batteries are like the tires on your car... they don't seem to wear much on just a single trip... but add up all the trips and eventually the wear is noticeable. Except in battery technology both age and the number of recharge cycles count. The electrons like to move around and it's acutally not good to store a battery too long without using it. I number my batteries and try to swap them so each battery gets some use and nothing sits unused too long -- and at the same time I'm also not using the same battery over and over.

After about 3 years... I know I'm probably nearing the end of a battery's useful life (though I've pushed it longer, I know I can't really expect much longer).

"Both the 5D III and the 7D have the ability to monitor battery status."

Provided you are using real deal Canon batteries. Some third world batteries do not have that ability build in them.

Are you saying that the problem has stopped? I do not understand your description of events, but if it is working, then I would worry about it too much. Be warned that it is usually a bad idea to swap memory cards between cameras. It doesn't matter if the cameras are the same model. It is a bad practice.

Reformat the memory cards in the camera that is using the card. If it is the SD card, be sure to perform a "low level format".

What am trying to say is that, any time memory card is inserted into the camera, the power will off, the camera only power on without memory card

If the camera wont power up with the card, then reformat the card. You wont be able to reformat it in camera, but you should be able to reformat it on your computer ... which hopefully allows the camera to start with the card in the camera. Assuming that works, then I would still perform another low-level format using the camera to do the format (cards should always be formatted using the camera where the card will be used. Do not swap cards across devices -- a card would basically be designated for use in that camera only.)

Memory cards can be flagged as "bootable" (this is how Magic Lantern works -- the Magic Lantern firmware isn't installed in the computer, it's just on the memory card but the card is flagged as "bootable" so it boots the card firmware instead of the in-camera firmware). However... assuming your card has been flagged as bootable, the camera isn't able to boot from it.

If the memory card is 32GB or smaller then you would format it with a FAT32 filesystem. If it is larger than 32GB then it needs an exFAT filesystem. exFAT can be tricky because I've noticed different OSes tend to use different blocksizes and some devices don't necessarily support just any blocksize.

If this doesn't work, then you need to get a new memory card.

I later put CF card and the camera work fine, immediately SD card was added it off again, so I have decided to be CF card till the time that I will send the camera for repair. I think SD slot has issue and a technician said I should not insert SD again till I av it repair so that the board will not be damaged.

The camera is not working fine with CF card inserted into the camera, but when I insert SD card, the camera off and didn't come up, so the camera only work with CF card and I test shoot some footage and play back with CF card which work fine but SD card still don't allow the camera to come up,
