View Full Version : Keyboard doesn't work after using superduper

06-23-2007, 12:13 AM
Hi, I made a copy of all files from my macintosh hd to my external drive. I restarted the computer booting from the external drive and everything was fine. So I copied all files from the external to the internal harddrive and restarted the computer with the internal harddrive. Everything looked fine until I went down to my dock. All the icons were screwed up. The icons were blank sheets and folders. I also noticed that the function keys on my macbook pro wouldnt work since I couldnt change the screen brightness or volume.
I thought this was caused by my internal harddrive being named "untitled" and not "macintosh hd" and this was causing the problems.

So I decided to redo everything and copy all files from my external to my internal drive. This time I made sure the internal drive was named "Macintosh HD." After it was done copying the files I shutdown the computer and disconnected the external harddrive. The computer took a little longer than usual to start up. After I logged in, I noticed the dock icons were fine but now the keyboard and trackpad on the macbook pro does not work. I can only use my external keyboard and mouse to control the computer. Also, I can't control my volume or screen brightness from my external keyboard.

Any help is greatly appreciated!

But everything works fine on the original copy when you start up from the backup drive?

No, now the keyboard/trackpad no longer works when started up from either drive. Whats strange is that I only made one back up of my original system. The first time i copied it to my internal drive only the function keys wouldn't work. The second time I re-copied it using the same backup is when the entire keyboard wouldn't work.

Did you back up from a different model Mac? I've never seen a keyboard stop working like this before, and it seems like it's a "unexpected hardware" issue.

-Nope, same computer.

Aright I figured it out. The first time I tried copying the drive back to the internal only the function keys wouldn't work. So I recopied the clone to the internal hd again just to see if it would make a difference. And this time the entire keyboard and trackpad wouldnt work.
It was driving me crazy! But I figured it out. So what was causing the keyboard and trackpad not to work? A stick of ram. When I made the clone I had 2 gigs of ram installed. Afterwards I had taken a stick out and was copying the clone with 1 gig of ram.

Now I don't know how the ram affects just the keyboard and trackpad but that was it.

Thanks for your help Dnanian.

Really! That's curious, but I'm glad you figured it out.
