I opened up my battery pack, it smelled like smoke

Get it to a good mechanic as soon as you can! An electrical smell AND smoke means a serious electrical short. Glow plugs use very high voltage so you risk a possible fire. There being no light means there could be a problem somewhere else in the system as well.

Hi you can download from here--

thanks

Smoking and a burning smell are not normal. Is the camera new?...can you return it?

Try these procedures.

First of all, forget the lawsuit if nobody was injured. Contact the support section of the Canon website for what you should do next.

See other questions/answers here, as this question is already answered.

You should send the camera with the battery for service to find out if there is a defect on any internal circuit boards, or if the fault is actually the battery. There is no reliable way for you to determine this yourself, unless you have the proper setup and training to service these cameras.

You mean SD400 camera doesn't show any error sign and it just doesn't have live view to shoot picture?
If yes, its problem of bad CCD imager and Canon will provide free of cost repair facility for SD400 camera.
Click Canon CCD Advisory for details.

I read a part solution on your web site about my Canon sd400 failing to start. The message gave a few free words about a micro swith in the cover. I couldnt find it! I called Canon tech and they said there was jo such switch. I packed up the camera and sent it off for a fix and a free firmware update. Probably going to cost $80. But I think it was the right thing to do!!
