How can I unroot without a power button?

[icky_jk]

So my Thunderbolt is currently off with a broken power button. I cannot turn it back on

I've called customer support and they're sending me a warranty replacement

I need to send my broken one back, but it needs to be unrooted first so I don't get a hefty charge added to my bill

Is it possible to unroot without a power button while the phone is off?

or is it possible to turn the phone on without the power button? I don't just mean wake it up, but actually turn it on

(Yes, it is the power button that's broken. Pulling the battery out for a few hours and trying again is not a fix)

Can any one help or offer suggestions? Please and thank you!!!

I personally wouldn't worry about it. Seeing as you have a physical issue with the phone and not some hardware issue. I say leave it and send in as is.

Someone posted once that plugging it in and pulling then replacing the battery apparently forces a reboot/restart.
