Or, if you can't do that because it won't turn on, tell us as much as you can about them?

Otherwise all I can suggest is pull the battery out for a couple of minutes, then try to turn it on again. Put it on charge if necessary. If you cannot get it to respond at all there is nothing you can do apart from repair, but if you can get any sign of life then tell us what it does and we can see what the options are.
