Subject: Macbook RSS (Random Shutdown Syndrome) fixed
Hi Mike, I just repaired a macbook with Random Shutdown Syndrom. Perhaps it might be interesting for your site.

How to:
If you are fit in soldering it is an easy job.
Disassemble the top case and lift the heatsink with fan+cables.

Next step: Look at the small black cables, in my case they were melted to one block and sticked on blank metal (heatsink). This causes a short circuit and forces the system to these immediately shut downs.

I decided to position the new cable section far away from the heatsink and mounted them on the fan housing, fixed with hot glue.

Pay attention to the cable's height - the topcase must fit.
The fourth cable I run in the space between heatsink bracket and fan, surrounded by thick shrinkage tubing.
I also mounted extra paperboard between the heat shrink tubing and the heatsink to protect the isolation from the heatsink«s heat.
That is all, assemble the macbook and perform a long time test if modification is successful.
Regards Juergen
