No Power Battery needed charging, charged it, placed in the camera as usual,s till no power. Just brought a new battery with the hope that the battery is faulty or past it's sell by... Have to say though.. the manufacturer said that there is a little power in the battery so I attempted it to see if there would be any joy, alas still not powering up. I currently recharging the battery to see if this does the trick... however not hopeful... Quite surprised that such an expensive bit of kit is faulty only just 8 months occassional use.. Will update the outcome...

SOURCE: xti wont power up

appears to be a defect and not user serviceable.
sorry for the news.
good luck.
mark.

Your camera is still under warranty. Recommend letting Canon try to correct this, instead of trying to fix this yourself.

Here's the support page for your camera:
http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&tabact=SupportDetailTabAct&fcategoryid=221&modelid=14905

Or you can call them directly at 1 (800) 828-4040.

Rechargeable batteries don't produce enough voltage to power the camera. I tried using them and couldn't get much life at all with an older camera, and then noticed that the rated voltage for rechargeables is 1.2 volts. New lithium batteries put out over 1.7 volts, and new alkalines put out over 1.6. I've had to ditch the rechargeables and just use lithiums to get the best life.

It's a scam that the rechargeables don't do any better than they do. All you can use them for is dim flashlights and kid's toys.

Well, I'm the 12th user. Just wanted to post that my camera had the same issue at 13 months old. I'm about to take it in for service under warranty. Hope I don't run in to problems getting it taken care of! This site was very helpful in helping me determine the issue.

SOURCE: Canon 40d-pressing the shutter seems to short out the camera.

I recommend that you remove both batteries for ten minutes to get a full reset. you spoke of the main battery. When you open the battery compartment, look at the lower right toward the camera with the LCD facing you.
It is a little hard to see, but will say CR2016 3V. Stick your fingernail under the lip and just pull it out.
As I said I left both batteries out for about 10 minutes.
You will have to re-set the date and time after your done.
