Well…I'm the idiot. When swapping out my ram, I broke the tabs that keep the ram boards in place. (See step 4 - RAM in the topic called "Installing MacBook Pro 15" Core 2 Duo Model A1211 RAM").
What part(s) do I need to replace? Apple says I need to replace the mother board. But when I look at the mother board, it doesn't show the ram assemble/tabs.
Any ideas?
