Okay, I've never heard of this happening to anyone... I just had to give up my oh-so-convenient airport for dialup access. I tend to move around my room with my iBook (800, 14 inch), and just this afternoon I grabbed it without realizing the phone cord was still plugged in. When I hit the end of the cord, the computer was yanked back since the cord was still in the modem port. I didn't drop it, all I had was the pull - not even too strong. All of a sudden, I got a screen flicker, and then it froze. Rebooted, and at the loadup screen (that gray thing with the startup indicator), it does the same thing. All I can think of is to open the darned thing up and see if any connections are loose... Just my luck, I was about to sell the darned thing too.
Any hints on what to check out?
