Help! Electrocution question

I am writing a novel in which there is a scene of an electricution in a Jacuzzi
and I was wondering if anyone can help me out with the technical details.

Two men are in a hottub. Would they be electricuted if a laptop computer fell
into the water? Or would they merely be stunned or perhaps would nothing at all
happen? Would the laptop need to be plugged in to harm them?

What if one of the two men was an epilectic or had a similar medical condition
- would be react differently?

If anyone has the answers or could point me to a source for this info, I'd
appreciate it.

Thanks,
