Hmm, sounds like something isn't seated right. Take
the machine farther apart. On some Dell laptops, there
is a power regulator board that plugs against the
motherboard with a couple of flat white connectors.
It's held down with a screw or two. Same kind of
arrangement is sometimes found on older machines with
processor boards (as opposed to bare chips). When a
laptop gets dropped, it twists the plastic case out of
whack, and unseats things like this. Remove the board,
dust it, and firmly reseat it. Any other kind of
module should be reseated firmly as well.
