I have the same problem. Function keys work, but none of the letters or numbers work, so I can't log in in hte appropriate field. I can move the icon with the mouse, (bluetooth or USB) I've tried 2 keyboards, one USB the other Bluetooth, but I can't get past the log in screen cos the letters & numbers don't respond. I can adjust the brightness using F1 & F2, and I can adjust the volume with F11 & F12.
Luckily I have this MacBook Air!
It started off as a hardware issue where I couldn't even start up. Also I can't get a hardware test to run to completion (you know, switch on whilst pressing D). Strange that the D key works for this!
Any ideas anyone?

Hey, I had that very same problem for about an hour but after panicking for very long minutes and searching for a solution, it just started working by itself! I did absolutely nothing to it, so I suggest you to wait? How long has it been anyway?

It started on Wednesday night. All programs froze when I connected a USB stick. After Force quitting all programs, the computer would restart, the loading bar got to about 20% then it just switched off. ;-(
