Anyone know a trick for rebooting without the power button?

So, after a week in a Utah canyon with my Lumia 1020, the power button has stopped working.(sand everywhere, but got some great photos) Now something is hung with Wi-Fi and I can't turn it off. The settings page just hangs when I try to do anything with Wi-Fi. So, I want to reboot my phone but don't have a power button. Any ideas? Btw, I have a replacement button strip on the way, but need to get by in the meantime.
