14 Every keyboard has a SysRq button. On most, it is shared with PrtScrn.
15 However, I've also seen it shared with either an F key or ScrollLock or by
16 itself. Also, I've seen laptops where you had to hold the Fn key to get a
17 key that acts like SysRq.
18
19 I guarantee you've got one, although I suppose it might not be labeled
20 SysRq at all.

31 Please *try* the Alt+SysRq instructions if you haven't already. Those are
32 handled directly by the kernel at a fairly high priority. I've had
33 everything else be ignored, including C+A+Del, and had Alt+SysRq save my
34 filesystems. It is possible that you might not see anything happen after
35 E, I, S, and U, especially if you were previously in X, since the kernel
36 is trying to write to the text-mode console but things are happening
37 unless your kernel has crashed.
38
39 All other keystrokes travel to user-space to be processed, so if your
40 kernel is busy, they won't do anything.
