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:

Another issue is: it seems the free maintainance announced through http://support.apple.com/kb/TS2377 seems to be obsolete, isn't it ?

    Finally resolved...

    It's because of the fact that my mbp is too old to be upgraded to lion ...

    Although I've seen successful experiences of upgrading mbp 895 (manufactured by the end of 2007) to lion, it's a disaster due to random death halt according to my experiences..


    It seems 10.7.4 could be OK since I have met no problems for more than one week, however, when upgrading to 10.7.5, the death halt happened every half an hour, while even if I downgraded to 10.7.4, it doen't help, while when I continuously downgraded to snow leopard 10.6.8, it works normally.
