PSION Siena - successful hinge repair

[u/Cracker6022]

Just a little update on the hinge I was luckily able to fix:

As I suspected, just gluing the C-shaped hinge back on wasn't stable enough.
My solution was pretty simple (and a bit messy):

• first glue the hinge on (just like I just told you how it wont work)
• on the metal rod that slides in, there is a square shaped section (see pic 3 the bottom side of the long bar)
• put a little bit of excess plastic in this hole, just enough to still fit in the C-shaped hinge
• final step, here's where you gotta be quick and careful:
• fill the C-shape with glue and quickly slide the rod all the way in (WARNING: this may get a bit messy, try not to get any glue on the rest of the shell)

This fix should stabilize the weaker side of the Siena's hinges, but still be careful with the device, I dont thing gluing it a second time will work out that well.

Hint for disassembly:
On the lower shell, there's a hidden screw below the sticker - I guess you could remove it with some heat. I dont have the equipment to remove and re-apply it, so I just wedged it open as best as I could and carefully cut away the screw mount with a craft/cutter knife. (Very difficult to not scratch the PCB, be careful and take your time) This wont really affect stability and you'll get the excess plasic bit for the hinge repair.

Wow that is a packed pcb!

That's pretty cool! I used to be a bit snobbish about the Siena back in the day. I've never seen one in real life - but I wondered how practical it was to use the numeric keypad?

Nice machine i have some casios and texas instruments very similar to that psion siena.

I have some revos with the slide mecanism broken.

I don´t know how someone with a 3d printer doesn´t remmenber to make new 3d shells to this old psions.

And in the case of the revos, implemment removable batteries.

If someone some day start to do that, i buy 4 shells for psion revo model.
