In the old-line IBM PC PSU's, there was always a big label on the
outside 'No user servicible parts inside' and a non-standard screw
sealing it. Every one that I've opened had a socketed fuse inside.
Haha, reminds
me to tell about a headless screw... has no slot,
just blank head where slot or hole for the typical screwdriver's tip
to fit in. Tony told me to bite on it with pair of pliers and
turn. They does unscrew. (!!)
I wonder if they were shear-head scews. They had a head once (probably
a male hexagon to be gripped with a normal spanner), but it was
designed to shear off when the screw was fully tightened. They're used
for things like car ignition switches (so a car thief can't easily
remove the lock from the steering column).
That was on PC RT PSU housing.
Now why you'd want to make a PSU so difficult to repair is beyond
me...
