Recently, I upgraded my mbp which was produced by the end of 2007 (macbook pro 895) with geforce 8600m graphic card, from 10.5.8 to 10.7.5.

I noticed that logic board failure might occur on my mac, however, at least i was fortunate during past 5 years while not that lucky just after ugrading..


My phenomenon is: the screen suddenly distorted and the overall system hung without any response until I power off and restart. I am not sure whether it's just the logic board failure, but I feel that it might have something to do with software as shown in: 10.7-lion-upgrades/


Another issue is: it seems the free maintainance announced through seems to be obsolete, isn't it ?
