Hey all --
I've had this HP 2100S mini sitting on the bench for a bit, waiting, and I
wanted to go through the power supply and test/reform the capacitors this
past weekend. The processor service docs cover getting the supply out
(which is slightly cumbersome) and I have that step done. But neither the
processor docs nor the power supply service docs seem to cover how one
disassembles the supply itself. (Has a really thorough guide to how the
thing works though, that I'm hoping I won't actually have to use anytime
soon.)
There are a lot of parts in this unit, and I'm not seeing a method to the
madness. The capacitors are fairly easy to *get to* but actually removing
them for testing / replacement seems to be another matter entirely. Anyone
out there done this before and have any advice?
Thanks!

Josh: Did you figure out a safe PS disassembly procedure? If so, what and how did it
go?

No, I didn't. I'm going to have to devote a fair amount of time to a
careful disassembly with copious notes and it's not something I can commit
to right now, so it's reassembled and back on the shelf for the time
being. I'm used to HP gear being a bit more user-serviceable, but I guess
they did have a ton of stuff to cram into this supply and not a lot of
space to put it in.
