It happened to me twice already. When I awoke my Macbook Pro from sleep, the whole screen was filled with a checkered pattern with some green and pink pulses. What could this be? I could not restart because the keyboard was not responding. I had to remove battery, reinsert and restart. It's OK now but I'm afraid it will happen again.

    Same thing is happening to me. From left upper corner to lower right, checkerboard lines...

    Then you see a box under curser made of lines, then freeze up!

    What worries me is the last computer I had, a 17inch powermac had this issue, and it was a motherboard replacement!

    What have you learned?

    Mine started doing that right after the warranty expired. Seems to be getting worse. It happens to mine if the power cord isn't connected when it returns from sleep mode, or if you disconnect the power cord while it's on. The "calculating" message appears next to the battery symbol at the top of the screen, then the screen turns into little blocks and freezes up. The only way to get the thing working again is to remove the battery and reinstall it.

    Everyone told me how much better Macs were than PCs, and like an idiot I listened to them. This is my first Mac, and will be my last. In my 25 years in IT I've never had a nearly-new laptop go south on me like this. And Apple's warranty period is a joke.
