How to reset when home button is broken?

Hello everyone!

The Home button on my iPad 2 stopped working a couple of days ago. I looked online to see how to "fix" this and configured the iPad so that the button is now on my screen... Not the best thing, but it does the job.

The day after the Home button failed, my iPad stopped charging. I stopped at the closest Apple Store, saw a tech at the Genius Bar, she tested it with a new cable and it worked. Great! Just 20$ to fix the problem!

I'm currently on vacation ( of course this has to happen while you're on vacation... What would be the "fun" in having iPad troubles when you're close to home.. ;-) ), so when I got back to the hotel, I plugged it in to charge, but after trying 6 different outlets, I still didn't get the charging battery sign.... So back to the Apple Store... When I got there, plugged it in with the new cord and it worked! Then the tech came to have a look at it, saw that it was charging, thought I was insane (!!!), unplugged it, plugged it again and then, next to the % of battery it said "Not charging".... Unpluged it a few times, tried wiggling the cord, and then it started charging again....

I still can't get it to charge at the hotel, but now, I would like to do a hard reset, but with the Home button not working, how can I do that?

Thank you for your help!
