I have a 15" 1.33GHz PB with 10.4.2 installed. My F1 -F5 keys no longer work. Nor does the restart button. My expose keys, F9 -F12 do, however. It's not the keyboard, because I find that I cannot restart from the Apple menu, either. This has happened before, but I don't recall what fixed it. I have run fsck, permissions fix, etc, but no love. The only way to restart the machine is from the command line. Anyone else experience this??

Wait a minute. Can you not even push the power button to bring up the slee/restart/shut down dialog box? Try resetting the PMU. Follow the instructions at Apple for your machine.

Do the keys work if you hold down the function key in the lower-left corner?

Maybe the Use the "F1-F12 keys to control software features" checkbox got checked in the Keyboard and Mouse control panel.
