No, I haven't the slightest idea, especially since you didn't bother
supplying the manufacturer and model number.
If you're missing parts, you can find just about anything from various
online computer salvage operators. Also on eBay. Be prepared to
overpay. The few surviving repair shops that actually do their own
repair usually have a fair collection of scrap parts laying around.
Ask, and you might receive.
Fractured at the screw point so only half
the screw hole remains , a highly stressed point, going by the amount
of
force required to turn this pintle rod.
I've used hili-coil inserts to fix those. Also threaded brass inserts
commonly used in plastic molding. Drill it out and epoxy the insert
inplace. The smallest you can get is 4-40 which is a tolerable
substitue for the common 3mm metric screw. I've also mixed aluminum
dust with epoxy and built up the broken part sufficiently to thread
the hole. It worked, but the owner had to be very careful when
opening the hinge. It lasted about 3 years, which isn't too horrible.
All these methods were a PITA and far too much work. If it ever
happens again, I'll just epoxy the hinge to the base metal and be done
with it.
You might want to look at hints at:

Incidentally, such breakage usually happens because the screw wiggles
loose. I recommend Loctite on enything threaded into aluminum.

Thanks for some interesting ideas. I was thinking of using some
expanded
aluminium, anchored into the aluminium, with a fresh drilled small hole
or
two and small nut/bolts. To give a scaffold for epoxy to anchor onto.
Also
underscore the plastic to give a bit of key. What is the function of
aluminium dust in epoxy, other than a colourant?
To the others in the thread , if I wanted to get hints on (apparently ,
oftn
walletctomy) buying specific replacement stuff from e-bay or how to
google
I
wouldn't be posting repair queries to sci.electronics.repair which has
the
word repair in the title. Why do you think I deliberately did not
mention
make and model?
Sometimes, my friend, you don't do yourself any favours. With an arsy
attitude like that, you don't deserve to get help with your half baked
bodge
repair projects. I offered you a solution based on the activities of a
friend who is a proper professional at laptop repairs, that would not
have
cost you a lot of money, otherwise he wouldn't be doing it, as he makes
a
proper living at it, and I wouldn't have suggested it to you, knowing
your
penchant for fixing everything with some **** dissolved in epoxy, and
some
obscure material not intended for the job. So go ahead, and waste forty
quidsworth of your time, on a bodged repair that won't last five
minutes.
Sheesh.

Oh well said that man -

If I replaced the whole hinge, I'd have to find out how to take the laptop
apart to get to the other part of the hinge, C-clip or whatever is buried
inside. Anyone's guess what chance of colateral damage just doing that.
Obtain a part, without being ripped off and having the correct one supplied.
Whereas all I've to do is find a way of building up the lost few square mm
of aluminium of the hinge anchor plate and make good some of the broken away
and missing plastic of the display surround/lid. All nicely exposed and easy
to work on. Why go to all that bother if a bit of epoxy and some Al mesh/
minimal hardware/drilling is all that's required. The hinge mount failed in
quite normal use , so direct replacement likely to do the same.
