iBook down

My iBook appears to be dying. It started playing up a while back, mainly with the AirPort it wasn’t dectecting networks when I woke it from sleep. The my iBook started Kernal panicing, and now it will on turn on in safe mode. Even then it can’t find the Airport card. Think I will be taking a trip to the Apple store in Nottingham on Monday. Doh. Hope it’s not too pricey!
