one row of letters on keyboard not responding

I was typing away at an email this morning when the row of letters starting with "a" just stopped working. So the keys a,s,d,f,g,h,j,k,l,; along with all their shift counterparts and anyother combination I can think of don't work. Funny thing is the ' key works just fine.

I didn't spill anything on it, drop it or do anything else I can think of to cause this. I have tried repairing permissions, restarting all to know avail. I connected USB keyboard works fine and ALL the other keys work just fine as well. I also check the num locks and caps lock keys - still no working.

I have a tech repair guy who said it doesn't sound like the keyboard is bad but he hasn't actually looked at it, only gone on what I said. Is there anything else I can do?

All the other keys work just fine, backlighting works fine on ALL keys. I have also reset the PRAM to no avail.

I did check out the website you mentioned but doubt it would be a lose cable only effecting the one row. Certainly could be but I am going to wait a few days and try some more things. For right now a USB keyboard is helping me get along.

Just wanted to say a big thank you for the tip, as the bottom row of my venerable PB17 G4 stopped working this week (keys Z-to-?) and removing the additional Crucial 512Mb stick and rebooting solved the problem. I was just about to open everything up and check the cable and then would obviously have found nothing wrong, and would have had to send the computer in for an expensive tech repair. Now all's I need is a new RAM stick. Thanks again!
