Canon powershot a520

CoolJoe72 only posted one answer, but it was a good one, and it applies directly to you. Check it out here: http://www.fixya.com/support/t313710-having_reset_date_time .

(The short answer is that you need to change the date battery, which you'll find under the terminal cover; it's a CR1220.)

the camera may need to be serviced

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 Windows Photo Gallery or any other photo cataloging program.

You can't do that in the camera. You need to import the picture into an editing program and crop the picture.

there is a little switch on the left side of SD cards; if it's down, your card is locked and you cannot copy anything on it or delete anyfile, also you cannot take any picture by it. so you have to change the switch postion. just this! I hope this helps...

check the battery/try replacing it with fresh ones

Did you accidentally hit the "DISP" button on the back of your camera? It manually turns the LCD screen on and off to save batteries.

Same problem here.

Very Annoying!!

I had a similar problem. Lens came out , and will not go back to off position. Will not tun on either chnaged couple of batteries with no luck.

I took the memory card out and it worked " Turned on". I formatted the memory card and it started working fine. Hope it will help few of you.

Good Luck
