Indeed, a CPU board screw (bottom left) came loose in my machine. If I'd
known what it was earlier I'd have fixed it right away, but I don't think
it actually contributed to my 2400's death anyway, because the machine was
sitting flat for days before it went.
It's safe to say IBM followed their own practice, and IMO the inside of the
2400 looks more like a Thinkpad than a Powerbook. There are just too many
little screws, layered boards, and generally a whole lot of little off-the-
shelf parts held together with intermediary resistors and string. Compare to
a Duo or 100 series, where half the chips are custom ASICs and everything's
in one place. Granted it's cheaper to make them the IBM way, but sometimes
you get what you pay for.
But someone really liked little screws when they built this thing - aside
from the risk of loose ones, you could leave half of them out and not affect
it structurally plus you'd probably shave half a pound off the weight. ;)
