Here's a similar question: How can I boot my Nexus S with a broken power button? Can only boot to "Do not turn off target"

Best thing to do is get the power button replaced. It is not too expensive.

You can also try the battery or bump tricks described in that chapter to try to get your Nexus S to boot while plugged into USB, but that seems like a short term solution.

Further to above, once you get the phone on by bump trick or fixing the button, remap power action to the search soft key and set awake on volume button press (available in CM and many other custom ROMs). I read about the power button when I got my Nexus S, and have done this as a precautionary measure since day one. –  Sumesh Jan 8 '13 at 17:58

You can fix this issue by simply opening the phone up by removing the 6 screws on the back, and fixing the power button yourself. What is happening is there is a ribbon connector that goes from the power button to the circuit board and this becomes loose and disconnects itself. You can simply press on it and reconnect it to the board to fix the power button issues. This will only be a temporary fix, as the phone is a poor design and will become disconnect more and more frequently. But this can at least let you use your phone.

There is no such ribbon connecting the power button to mother board, its soldered onto the board. –  digitalPBK Apr 21 '13 at 6:27

You can remap either of the volume buttons to be a power button. I have remapped my volume up button to power button.

To remap, you should have rooted phone, with terminal emulator and busybox application you can edit the file /usr/system/keylayout/herring-keypad.kl

change the line

key 115 VOLUME_UP WAKE

to

key 115 POWER WAKE

And reboot your phone.
