Ok so I’ve done a bunch. I use a flathead small screwdriver right near the connector on the bottom and begin cracking and separating it at the bottom. Then I move it around and separate the two halves.. the nice thing is any marks are small and by the bottom of the wire coming out.. I’ll try to take a pic to explain.. sometimes you can crack the sides by pushing in. I’ll warn you if you have a really dried out plastics they just crack and break. I offer no warranty’s or success with this. I’m simply telling you how I perform this. Good Luck

My 145b adapter opened pretty easily by heating up the glue with a hot air gun and then squeezing the sides. My PB520c adapter was a nightmare and had to be cut open

I tried that using 2 screwdrivers and a clamp and it didnt do anything except squeeze the capacitors juice out im afraid of the capacitors exploding and a fire hazard . I guess i should keep trying though

Never had any issue with that trick. 

 

Two screwdriver rods, one on each side and a good vice is all that is required. 

 

Two minutes job.

Jesus, how hard did you clamp down?  I honestly think you'd best not repair things yourself

yikes. I guess the caps were gonna need replacing anyways...??

If it doesn't come apart with the vice strategy, honestly, it's probably going to be a pain and cutting it open might be the best solution to avoid further damage to the internal board. (Although "capacitor juice" is most likely indicative of a goner.) In that case, brittle and dried plastics aren't really going to stop you if you have a nice tool and a steady hand.  good luck!

Sometimes I think thats true esp with old computers lol. I didnt put alot of pressure at all. It was a smaller vice and the thing wasnt budging at all. All of a suden its got some brown juice oozing out

That’s just HOW bad those caps are leaking. There’s so much fluid loose in the brick that it’s oozing out now. There’s a few ELNA caps in there that leak really bad.

Vice with two pencils or rods works great. On one I did have to move the rods around as it didn't 'snap' open - squeeze, move, squeeze, move - but eventually it came apart. And by eventually I mean 5 minutes tops, so not long at all.

 

But no one prepared me for the smell that first time. It's ungodly. I once had an old cat with failing kidneys that would relieve itself in the living room corner, poor thing, but the smell... concentrated-urine-from-a-dying-cat smell. It's like that.
