Hi all
Just returned to my Macbook ant the keyboard has completely ceased to function. Absolutely nothing works. Tried a restart and permission repair, still no keyboard. A USB mouse works, but that's all.

Any ideas?

Thanks

Faulty cable that connects the keyboard to the motherboard, or something is preventing the signal reaching the motherboard. See an Apple genius pronto.

Does the trackpad work and does an external keyboard work?

And it might be a stupid question, but is num lock on? I've thought my keyboard stopped working before but it was because num lock was on...

To my surprise, when I rebooted, my trackpad and keyboard were dead! Dead dead. Not even available for a PRAM reset during boot.
So I borrowed a USB keyboard and mouse, which worked fine. I tried several things, for two hours, until I found another MacBook Pro EFI Firmware Update.app from Sept. 27, 2007. I installed that, which rolled me back, I guess. Then I got my keyboard and trackpad back.

Thanks guys.
Track pad doesn't work either. Just about to plug in an external keyboard to see if that works.

if both trackpad and keyboard are non-functional, the usual culprit is the topshell cable - it has either popped out of its pressure-fit connector (not unheard of) or broken (rare).

Try booting from your Mac OS X Install DVD and see if the keyboard & trackpad work there -- if they don't you have a hardware failure, and its time for your lappy to see the Apple doctors at your nearest friendly reseller.

Hi again.
Thanks for all the advice. After leaving the computer off for a while and re-starting it was back to normal. Not convinced that it's solved the problem, but at least it's going for now. Once again, thanks for all your thoughtful suggestions.
