I have finally taken my A1200 apart so many times that my case threads stripped out.
I came up with a fix that still utilizes the stock screws...
Parts:
Wire nuts
2-part epoxy
dremel tool
shish kabob skewer
large screw
1. Using the large screw remove the springy thing from the wire nut. This springy thing will work as a helicoil(TM). my springy things were a little long so I clipped a few rings off of the top.
2. Use a drill or dremel to enlarge the screw hole so the springy thing fits. Fill the entire column with epoxy.
3. Insert springy thing and use skewer to force out excess epoxy.
4. After letting epoxy dry, reassemble A1200.
Hopefully you don't need steps 5, 6 and 7 which are disassemble A1200 because the HD LED is not working, reconnect FastATA wire that came off and finally, reassemble A1200.
