Mac mini Late 2012 lower RAM socket stopped working during Mojave installation. Re-installed Sierra, but no luck. Only screws near the RAM sockets are two which fastens the blower through metal tubes to the logic board. No sign of other screws nearby after unscrewing the blower. Any other screws somewhere I can try? Thx Les
Only one rubber tube in the four screws, though. Will investigate further.
One more issue:
Step 11 First picture FCB refitting. I can't seem to get the flex cabe back into the slot.
Is the connector plating supposed to go in at the top? I have an X10 which is very much similar to the X20, except for this flex cable which is not twisted as shown in the third picture (Step 11).
