lid shut laptop = high cpu load?

[Zach]

Would be interesting to see complete top output, to see what process
is hogging resources.  Does it do it every time you close the lid, or
just this once?  If it's every time, then likely it's something that
one of the acpi scripts is trying to do.

Not sure if you did this already, but you may want to install ssh,
then ssh into the box before before you close the lid.  Start up top
and any other tools you want to use, then close the lid.  top has a
way to write it's output to disk, though I'm not sure what it is right
now.

You may want to pipe things through tee to get screen output as well
as writing to disk.  That way if the box quits responding, you'll
still have stuff written to disk for analysis after you reboot.
