How can I boot my Nexus S with a broken power button? Can only boot to "Do not turn off target"

My Nexus S power button has stopped working and Samsung will not honor the warranty. The farthest I've gotten is to the Downloading screen with the yellow work ahead sign, that says "Do not turn off target" and USB Control Init USB Control Init End. My computer does not find the device via the Android SDK. I looked up this post https://android.stackexchange.com/questions/22640/turn-phone-on-with-adb-or-fastboot and others outside of this forum (eg: removing and inserting battery with charger connected), but it does not work for me. Once I boot it I can use it by plugging a battery charger or cable to turn on the screen. Is there a way I could boot it?
