Opening up a PowerBook 500 series AC Adapter (Model No M1893)

[twillkickers]

I am trying to open up an old PowerBook 500 series AC adapter to recap it. However I can't find any instructions online of how to open one. Has anybody opened up one before? Are there any screws under the sticker need to undo first, or should I just start trying to ply the plastic open at the divide? Thanks.

IIRC no screws, pretty hard to get inside one of those.

I can confirm. Just peeled off the label and there were no screws under there. What tool did you use to get it open?

careful with these. the plastic is as brittle as glass.

Sorry for the late update. I basically destroyed the plastic getting it open. Still not entirely sure if there is a proper way. If someone has a good fix tutorial for these it would be appreciated!

Nope. Pretty much just broke into many pieces when I tried to get one apart. I ended up reassembling the various plastic bits and wrapping the whole thing in duct tape. It has held up for years like that. A rotary tool of some sort may be a good solution though.

I opened one of these by drilling small holes and then used snap ring pliers, a small dental type pick, and a plastic pry bar. When the plastic wound't separate, I drilled another hole then scraped plastic out between the holes with the pick then separated with the pliers. Not pretty, a few gouges but not destroyed. I attempted a recap without success..its still not working, so I just used the cord on a toshiba power supply as described in a previous post. If you want the case, then message me...its about to end up in a box never to be seen again.
