Baking Soda soaks up the superglue quite well. It’s easier to use than the steel powder. I’ve used it if there is some of the original plastic left to bond to. Useful for other stuff too.
But the resultant solid is not as sturdy as using powdered steel dust (at least I’ve convinced myself of that) . These crappy little mounting posts are subject to both compression, shear, and extension stress.
JB putty would work great, but it doesn’t stick to plastic as well as regular JB or superglue.
Once the joint starts to go, unless the user takes remedial action quickly, the little posts crumble and you’re are left with the little brass inserts unsupported by anything other than the surrounding components.
This user had the screen duct taped together to keep it from coming apart. The hinge was forcing the screen to pry itself asunder.
On this particular laptop the hing actually has a component that floats unsupported and acts as a lever to the hinge mounting points. I made a support to brace it from below so it doesn’t have a chance to flex as much. Popsicle stick shaved thinner and cut to shape did the trick.
Dell, in it’s wisdom, peens over the threads on the hinge pin. Making nearly impossible to disassemble without taking the whole frigging thing apart.
And don’t get me started on cable routing through the hinge area.
Dell isn’t the only company that has great ideas. There are some Toshiba laptops that are great PCs. I’m typing on one now. If the keyboard goes, the replacement is relatively expensive as laptop keyboards go. BUT, it’s attached to the top clam shell with plastic studs melted into the mounting holes on the keyboard.
So to remove the old one, you melt the studs with an iron. Shape them us as best you can so the new KB will fit. Then hope you have enough plastic to work with to secure the new KB. Or try superglue and baking soda
How do you quote a repair like that? Well, if it works, it will be 2 hours in labor plus parts. But it might not work. And I won’t know if it works till after I’m done.
Good to know about UV not liking to stick to plastic. That’s key to doing this type of repairs.
All the Best,
