This happened to me recently when I was, umm, playing with the new Lombard.
My wife has a 400 Pismo, and I decided I'd see if the DVD drive from her Pismo would work in the Lombard. (I hadn't, at that time, read the Apple KB article that tells me absolutely definitely that it won't). I'd also been playing with RAM, and the HD in the Lombard - I think I'd had the whole of the processor card off, and the HD out (both these are candidates for replacement, indeed subsequently the HD has been changed). Anyway, I popped the Pismo DVD drive into the r/h Lombard expansion slot and booted up. The Chime rang, but nothing else - no 'white apple'. Then I noticed first a burning smell and then a whisp of smoke emerging from the ventilation slots at the back of the r/h side. So I pulled the power adapter out and popped the battery out, and thing went dead. My first fear was that the Pismo DVD drive had fritzed itself/everything, but on popping that out it was quite cold, and there was no evidence of heating around it at all. So that went carefully back into my wife's Pismo. Then I unhooked the keyboard and went back to the areas I'd been digging around in before. The processor card seemed OK, but the HD seemed pretty hot, esp as it hadn't really been on for any length of time. Further investigation revealed that the orange ribbon cable connecting the HD to the motherboard was scorched, in part of the wide area under the r/h side of the HD; indeed, there was a hole burnt through the cable. Looking carefully at the cable I realised that there weren't actually any conductors in the burnt area, so it can't have been an overheating wire. Then I found that a small hole had actually been burnt in the bottom casing, just below where the cable was. After leaving everything to cool down I reconnected, booted up, and it ran fine. Since then I've had no trouble. I've also replaced the HD with a 20Gb IBM (because the original was too small, not because of problems), and that went in without any problems. All I can surmise is one of two things: a) there is something in the Pismo DVD drive which caused this, even though it didn't seem to affect the DVD drive itself; or b) when I replaced the HD earlier I didn't seat the cradle properly in the sockets in the heat-sink chassis that are intended to accept it, and as a result the heat, being unable to dissipate itself through the heatsink conducted through the cable to a point on the casing that the drive was in fact pressing against. This was pretty worrying, of course, and not what I wanted to experience. Has anyone else experienced anything similar? Any knowledge about this sort of event 'in the community'?
