If you think there is a problem with the camera, first check the following. If the
items below do not solve your problem, contact a Canon Customer Support
Help Desk.
Power
Nothing happens when the power button is pressed.
• Confirm that you are using the correct type of battery, and that there is sufficient charge
(p. 201).
• Confirm that the battery is inserted facing the correct way (p. 17).
• Confirm that the memory card/battery cover is fully closed (p. 18).
• Dirty battery terminals reduce battery performance. Try cleaning the terminals with a
cotton swab and reinserting the battery a few times.
The battery is depleted quickly.
• Battery performance decreases at low temperatures. Try warming the battery a little by
putting it in your pocket, for example, with the terminal cover on.
• If these measures do not help and the battery is still depleted soon after charging, it has
reached the end of its life. Purchase a new battery.
The battery is swollen.
• Battery swelling is normal and does not pose any safety concerns. However, if battery
swelling prevents the battery from fitting in the camera, contact a Canon Customer
Support Help Desk.
