Last night my ibook G4 started to have the problem of repeated need to turn off the unit thru a pop up message. I suspect a logic board problem as stated in some threads. Brought the unit to digital hub at vmall this afternoon and will know the problem by tom or Friday. I know this has been discussed in the forums but my question is will apple extend my apple care for a couple of months to see if the repairs done with my iBook are ok. My apple care will expire this Feb 10, 2009. Thanks.
