How to troubleshoot sudden text input failure?
This happened for the first time since I started using this MacBook Pro in the last 10 weeks or so. The keyboard suddenly stopped working and the only keys that worked are the function keys (as special keys, ie., adjust sound brightness etc.) and the Ctrl+number to switch between expose screens. I have tried several other combinations and nothing else worked. Even after connecting to it over VNC the keyboard didn't work. It did recover after a reboot, but I hate rebooting, that is so windows like. I am wondering what techniques I could have used to recover from this situation if it were to happen again. May be there is something diagnostic that we can do to figure out the root cause? I am relatively a newbie, so anything would help.
Since you tried using VNC from another machine, this isn't a hardware issue; since the keyboard belonged to that other machine and worked outside of VNC, right? – Daniel Beck – 2011-05-21T05:53:31.920
Try
Ctrl-Shift-Eject
to shut off the screen. This should be another combination that works, since it cannot be intercepted by software, just like the function keys. – Daniel Beck – 2011-05-21T05:54:59.813I didn't try Ctrl-Shift-Eject so can't confirm that it works. Not sure if it helps to narrow down though. Yes, since it didn't work from VNC also, it is definitely not a hardware issue. – haridsv – 2011-05-22T17:46:19.060
Consider contacting NReilingh, the user that posted the question we assume this is a duplicate of, and exchange lists of the software you use. It's possible a third-party application causes this, so if you both use some of the same software, it might be worth checking those programs.
