Try with the magic SysRq key.

The magic SysRq key is a key combination understood by the Linux kernel, which allows the user to perform various low-level commands regardless of the system's state. It is often used to recover from freezes, or to reboot a computer without corrupting the filesystem.

  • Press and hold Alt
  • Press and release the key labeled SysRq
  • Press and release U. This saves any unsaved buffers to the disk, then forcibly remounts all filesystems read-only.
  • Wait until you see a message “Emergency Remount R/O” on the console. If you can't see the console, wait until all disk activity has stopped.
  • Press B and release the keys. Your computer will reboot.

  • You need to hold down Alt+PrntScrn+B. Either you missed the Alt key or you didn't post that in your comment. By the way, steps are: 1-Hold down the Alt and SysRq (Print Screen) keys. 2-While holding those down, type the following keys in order, several seconds apart: REISUB 3-Computer should reboot. – YoMismo Feb 19 '15 at 09:05

  • I don't think that will work remotley, you will either need to be in the physical machine or find/develop a program that launches that sequence remotely. – YoMismo Feb 19 '15 at 09:23
