My airport card for the 5.5 macbook pro 13 in unibody (mid/late 09 model) suddenly stopped working. It was working perfectly earlier this week in class/work, but when i brought it home (in a hand-held latched and padded case) I got an error saying, "airport card not installed." The trip from classroom to home took about 5 minutes, with no banging the comp around.

I went through the boot option-command-p-r and the other procedure as well (sorry forgot the sequence of keys) as indicated by applecare support people over the phone with no luck. Also, under "about this mac" -> "more info" -> network -> airport readout is only:

Software Versions:
Menu Extra: 6.0 (600.22)
configd plug-in: 6.1 (610.2)
System Profiler: 6.0 (600.9)
Network Preference: 6.0 (600.22)
AirPort Utility: 5.4.2 (542.23)
IO80211 Family: 3.1 (310.6)

with NO "interfaces" readout below that as there should be if the hardware were working or was plugged in correctly. I have also tried completely reinstalling the OS (newest snow leopard) to no avail. Note that when connected via ethernet, the internet works great. And my wireless network works great on my other machines.

Basically, I've come to the conclusion that the airport wireless card has come loose (had similar issue with RAM coming loose on the new iMac), and I can't find a definite answer anywhere as to it's location inside the macbook pro 13in 5.5 unibody, and whether it's accessible to plug back in correctly, or replace myself?
