Ensure that the camera is in focus by half-pressing the shutter button before fully pressing it. Also, check the image stabilization settings and set the ISO to a higher value if in low light.
To reset the camera settings, navigate to the menu, select the 'Tools' tab, and choose 'Reset All'. Confirm the reset when prompted.
Use a soft, lint-free cloth or a lens cleaning brush to gently remove dust and smudges. Avoid using any harsh chemicals or rough materials.
Connect the camera to your computer using the supplied USB cable. The camera should be recognized as a removable drive, allowing you to copy photos. Alternatively, use a card reader to access the SD card directly.
Reduce battery drain by lowering the LCD brightness, turning off the camera when not in use, and disabling unnecessary features like continuous autofocus. Ensure the battery is fully charged and consider carrying a spare.
First, check if the battery is charged and properly inserted. If the camera still does not turn on, try cleaning the battery contacts and ensure the battery door is securely closed.

Press the 'FUNC./SET' button, navigate to the resolution setting, and select the desired resolution from the options provided. Higher resolutions offer better quality but use more memory.
Check Canon's official website for any available firmware updates. Download the update and follow the provided instructions, usually involving copying the firmware file to the SD card and following on-screen prompts.
