As I have mentioned the school MinecraftEDU server before, now I need to disable the power button. The computer is in a place where many kids are a lot, so we need the power button disabled so nobody can turn off the computer. I tried just unplugging the power button, and it didn't like me for doing so. All the fans sped up and the hardware went a bit nuts. I haven't figured out how to disable it through the software, which is Ubuntu 12.04 64-bit. I hope someone can help!
