I was very interested to read this document. I think there is a problem with the Cinema Display and that it is frying the computer.
My husband bought each of us a macbook pro. His was hooked up to the cinema display. After about a year, his MBP started to suffer intermittent failures where it would suddenly shut off and have to be hard rebooted. After 2 years, the power or logic board on his MBP completely failed. He bought a new MBP and a Thunderbolt display, and I inherited his Cinema Display for use with my original MBP.
After one month of use with the cinema display, my MBP started to have the same problems. It has to be hard rebooted almost every time I disconnect or reconnect with the cinema display. I went to the Genius bar, and they confirmed that my MBP logic board needs to be replaced; I'm just holding out until spring break to take it back in, as they say it may take a week. Fortunately, I have AppleCare for my MBP.
Our cinema display is 3-4 years old, but it looks like, even though it appears to be working, I should probably get rid of it. I can't keep frying computers!
I'm posting this because I'm wondering how many others are experiencing this problem.
