Battery getting exhanusted

Sometimes, the lower contacts get bent downward after years of use, causing the batteries to ride low in the compartment, and thus making poor contact when the battery door is closed. Try lifting/bending these interior battery contacts upward, so that the batteries ride higher when inserted.

Contact failures may have occurred between the camera and the batteries.


Confirming that the [Memory Card / Battery Cover] is securely closed

If the [Memory Card / Battery Cover] is not securely closed, the power of the camera may not turn on.

Close the [Memory Card / Battery Cover] securely, and then turn the power on.

Clean the battery terminals with a dry cotton swab that has a fine and soft tip, and then re-insert the batteries.

If your camera uses four AA-size alkaline batteries supplied with the camera, follow the procedure below. In addition to Alkaline batteries you may use optional nickel metal hydride (NiMH) batteries.

replace the CR 1220 Circle battery located close to the AA Battery

Hmmm. With this, I suggest looking through your settings and trying to find a "power saver" setting. If that doesn't work, you could report the problem to the company. They should switch out cameras if you still have your warranty. 

Check for battery current ratings, Canon cameras need AA batteries with current rating above 1200 mAh, I use Energizer rechargeable batteries for my Canon Powershot SX110 IS. The batteries last more if we use the flash option wisely.

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!!!

there is a little coing battery located inside the battery compartment for the AA's. CR1220 you can get this at Radio Shack for about $5. If this battery is bad you will get the change batteries screen no matter how many fresh AA's you put in, Use a good quality alkaline battery such as the Energizer rechargable rated at 2700 mAh.

There is a battery charge level sensor in the DC/DC internal converter board.

It seems that just started to fail such board.

You can try with other brand or type of AA batteries.

If still you have the same problem, you will need to have replaced the DC/DC converter board on your camera. This means a Camera repair shop service on it.

Best regards,

MAYBE U WILL HAVE TO CHECK THE BATTERIES SUMTIMES THE BATTERY DON'T SAY THAT IT'S DEAD IT WILL....NO TAKE ANY PICTURES IT WILL CUT OFF OR U CAMERA TO POWERFUL FOR THE BATERRIES GET DURACELL...

I just fixed mine. Put your memory card into your computer. Right click on it. Choose format. Reformat the memory card. You WILL lose all pictures stored on it.

Before putting the memory card into your camera, do the following.

Go to MENU and choose RESET ALL.

Choose reset to original settings.

When camera is done doing so, turn camera off.

Reinsert memory card after it is done being formated in your pc.
Then your camera and memory card should work great again. I just did it on my Canon Powershot A620.
