Hi and welcome to the forum:
Sorry to learn you are having this issue. In order, I would suggest the following:
1. Make sure the battery is fully charged - you may be wise to get a battery charger for this model if, as I suspect, it does not come with one.
2. See if you can source a known good battery. You might be able to persuade someone who uses the LP-E17 batteries, or a camera store to let you try a charged battery to eliminate that the battery is not the issue, or the charging cable.
3. If it is clear that battery is not the issue, call 1-800-OK-Canon to talk to the tech support people.
cheers, TREVOR
