Any dilute acid, I guess (the battery electrolyte is
alkaline). Then wash
with distilled water and dry. No harm in then using isopropyl alcohol on
the boards to clean off other dirt, although that'll do nothing for the
battery problem
yeah, that what I think.
I have to gather up a fat painter brush (round one), vinegar, and
distilled water tomorrow.
There are several PSUs used in the 6150 from what
I've heard. One of
them is assembled by self-tapping screws with no slots in the heads (no
idea how they got them in, possibly they had heads that were then broken
off, like some security screws). It's worth gripping the heads with
self-locking pliers and trying to unscrew them.
Gasp, that was already defeated easily because they're too proud by a
mere common self-locking pliers. 4 of them but they're plain fine
pitch not self-tapping kind. I saw them with both security and
slotted screws all "wood self-tapping kind".
I've never seen blind rivets (as in, you can't
get to the back of the
panel after assembly which is the case here) which aren't of the
pop-rivet type. Certainly not in a computer anyway.
*Smacks my head*, that is how I sees those because it looked like
rivets to me. :) They're like slotless screws. :)
Oh yeah! there are one type that has twisted ridges that are pushed
in by machine. How did I know? That was from younger days when I
was stripping out guts out of old consumer stuff and car stuff. :-)
