After getting spontaneous start-ups at random times, I ran apple hardware test, reset SCM (I think I did it right,) and PRAM. Wondering how to interpret the error code beyond "failed sensor" and if I have to go running off for service / get them to interpret my code? Does anyone in this forum know what the codes mean? The computer has been operational otherwise, but want to prevent imminent meltdown if the weird startup behavior is the beginning of the end my MacBook Pro, early 2011.
