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!
