hey there, On Thursday I took my uncle's macMini to the local Genius Bar because it would no longer boot. The next day they returned it with the non-Apple 2GB SO-DIMM removed from the top slot and said my third-party RAM was bad. Well, no. It turns out it won't boot with any SO-DIMM in the top slot. So I took it back for a "quick drop" on Sunday. On Monday they tell me that they have ordered a replacement logic board. On Wednesday (today) I get the machine back. It does boot even though the top RAM slot is filled, however (1) I see white-on-black boot text when booting and shutting down, and (2) clicking the "Turn AirPort On" button has no effect--it continues to say "Status: Off". Any ideas on these? For the first, I notice lots of unexpected stuff returned by "nvram -p": Compare this to my machine, which has only I figure that could exlpain item (1), but could it also explain item (2)? Suggestions for how to proceed, anyone?
