S90: Change Battery Pack issue

Has anyone else had this issue? My battery pack will be charged, but turning on the camera will result in a "Change Battery Pack" message. Turning on and off the camera a few times will eventually work, revealing full bars on my battery charge. The issue is intermittent and only happens maybe 1 out of 3 days.

However, if I hold PLAY to turn on the camera and then press down the shutter release halfway to force it into shooting mode, it turns on properly. It seems like some people have suggested that the issue can be fixed with a different memory card (http://www.fixya.com …shot_sd780_chan​ge_battery or http://www.flickr.com …iscuss/72157624​408773819/), but that seems like a less than satisfactory solution.

I contacted Canon support and was quickly told to go ahead and send my camera to their repair center. My camera is still under warranty, but it seems like they aren't offering to pay for shipping. It also sounds like it isn't necessarily an officially recognized issue, so I'm not so inclined to spend the money to ship off my camera to a repair center for them since my camera still works, and I'd be out of its use for a few weeks. Especially since the issue is intermittent (what if they say they can't reproduce the issue?) and a different memory card potentially can fix the issue.

tried using another battery pack? it might be the battery and not the camera. also try doing a reset.

Sure everybody else has already found the "stuff a piece of paper behind the battery door" fix, but thought I'd just add a note.

It looks like the spring that puts pressure on the battery loses tension over time, and so isn't exerting enough pressure to get the camera to recognize the battery's properly seated. Folks have been stuffing a piece of paper or card into the compartment to increase the tension, but I didn't like that as a "fix", so I unscrewed the two screws that hold the door and spring/bracket onto the hinge, and gently bent the spring/bracket a little to add more tension, reassembled, and that's fixed the issue for me--no more "Change Battery Pack" false warnings.
