I have put the battery the wrong way round in my canon ixus 75 & now i cannot remove the slide cover to the battery & memory card. regards richard

Look at your memory card. SD and SDHC cards have a slide switch along one edge. The position farthest from the metal contacts locks the card, protecting it from writes. The position nearest the contacts unlocks the card.

The best way to download pictures from your camera to your computer involves removing the memory card from the camera and plugging it into a card reader (either built-in to the computer or connected via USB or FireWire). This is likely to be faster than connecting the camera to the computer, and won't run down your camera's batteries.

Once the card is plugged in, it will appear to your computer as a removable drive. You can use the operating system's drag&drop facility to copy pictures from the card to the computer's hard drive, the same way you copy any other files. Or you can use Canon's ZoomBrowser or any other photo cataloging program.

Take a look at your memory card. SD cards have a slide switch along one edge. The position farthest from the contacts locks the card, protecting it from writes. The position nearest the contacts unlocks the card. If the switch is already in the proper position, slide it fully the other way and then back again.

Remove the SD card from the camera. Slide the tiny switch on the side of the card to its other "unlocked" position. Reinsert the card in the camera.

But if you have already tried this, see this link for additional things that you can try.

hi..
1. Turn your device off and remove the battery cover and battery
2. Remove the end-cover by pushing the cover away
3. Pull the bumper tabs up to separate the bumper from the device and remove bumpers
4. Snap new bumpers firmly into place
5. Re-attach the end-cover, re-insert the battery and re-attach battery cover..

thank u
rate me!!!

Remove the card and look for a tiny slide switch on the side of the card. Slide it to the other "unlocked" position, and reinsert it in the camera.

Remove the memory card from the camera. Note that there is a small slide switch on one of the long edges of the card. Slide the switch to unlock or lock the card.

try moving the small sliding switch on the card to the "unlock" position. That usually solves the "card locked" problem.

Are you using a memory card or internal memory? If you are using a memory card, get a memory card reader and download the images onto your comp.

The manual states that the battery door was opened during use. Close the battery door and turn it on and off. You may need to push it closed to make sure the battery connections are made.
