Hey guys
Got a bit of an interesting occurance with my Powerbook G4 12" 1.33. Quite a while ago I dropped my bag with it inside, causing the corner of the frame to bend a bit and make it difficult to plug the power in, and make it stay. Finally, I decided to open it up and try to bend the frame back with the help of pbfixit. To my shock and horror, as I was unscrewing the keyboard from the underneith, I'm pretty sure I shocked the logic board where there it pokes through beside the RAM expansion slot I nervously put it all back together, and to my delight, it worked. Or did it?
My first KP occured while running tiger. I was unplugging the power, and as it changed power saving modes it crashed. I thought "oh well Ill just have to deal with this", but it turned out to not be such a regular occurance. KP's started happening with more frequency, in random places. Power plugged in or battery, many apps open or just a few. Highly frustrating. Unfortunately at this point I hadn't read about the log file so I didn't actually look at what the error messages were...
In desperation earlier today, I installed panther to see if that might somehow work. To my dismay, about 30 minutes after installing it I received another KP while just idling. At this point I started searching the forum, and figured out how to get the logs. Here is the one from that time:

Airport?? I was most confused... The strangest part of all was that after rebooting from that KP it has run perfectly for 9 hours, something it hasn't done since before I opened it up. Before I opened it up it has only ever seen one KP. The Apple Hardware Test showed everything as being fine, although I know that this isn't always true..
Any ideas guys?? Sorry about my long-windedness...
Many thanks,
Danno
