Thanks for the advice Jeff. And the link. I did take this machine
apart once about 5 years ago to replace the hard drive. That all went
fine.

That's a start. However, to reflow the BGA chips on the motherboard,
you'll need to remove the motherboard from the plastic case. I take
photos as dive into the machine. Seems to impress (or panic) the
customer. For example:

Photo of the above heat pipe radiator AFTER I blew compressed air into
the area from the outside. The only way to get the crud out is to
tear it apart.

Also, this one way it could be easily cleaned:
http://www.learnbydestroying.com/jeffl/pics/repair/Dell%20Inspiron%201525/index.html
The bottom cover comes off exposing the entire heat pipe assembly,
which is then easily cleaned. Too bad Dell (or Foxcom) designed it
into a crappy machine (Inspiron 1525) with miserable BGA soldering.

More later. Gotta run.
