It's been a while since I've opened a PowerBook since I'm no longer working for an Apple Authorized Service Provider, but I recall that there is a magnet inside the case along the back between some of the ports - I think to help hold the port cover closed. Perhaps it came unglued, and got attracted to the metal shell of the VGA connector. Why don't you take a nice closeup picture, and either E-mail it to me or send the URL to me and/or the list - I'll confirm if it's the right shape and size for this magnet, or if it's something else. As far as getting to it to either remove it or put it back in place, it would be difficult. You'd have to remove the logic board - it can be tricky getting it back in place once you've pulled it out. Also, you'd want to replace the thermal pad between the CPU and the heatsink after breaking the one that's there now when removing the logic board; and most average people don't have thermal pads lying around the house. ;-) John <simplymail at ururk.com> writes: > If I need to, I can post a picture, but... > > I have a PB G4, 550... > > and in the back, where the VGA port is, sandwiched between the metal > and "inner" metal, there is this round thing - I can shove it to the > side, otherwise it gets in the way of my external monitor plug.
