Qual è il Macbook Pro (con scheda video integrata) che vi è durato di più senza aver bisogno di riparazioni nel corso degli anni?
3 anni fa diversi miei amici e amiche mi hanno convinta a passare ad Apple perché ne esaltavano la qualità costruttiva, l'estetica, la stabilità del sistema, il supporto tecnico. Tutti a ripetermi: "Sì, lo sappiamo, è una grossa spesa all'inizio, ma consideralo un investimento: un Mac ti dura come minimo 5-6 anni!"
Come si dice, le ultime parole famose...
Oggi permettetemi di pensare: a che pro spendere altre migliaia di euro per una macchina che probabilmente ti abbandonerà tra 2-3 anni? O è sempre e solo questione di fortuna/sfortuna? Visto il crescente numero di casi per i Macbook 2011, risulta abbastanza evidente che non lo è...
Riporto alcuni commenti presi qua e là:
My Macbook Pro 2011 was also a replacement Apple had provided for the Macbook Pro 2009, which had flickering problems when on the battery saver mode (using the 9400m GT). After reading all these articles regarding dedicated card failure of Macbook Pros year after year it seems to me to all Macbook Pros with dedicated graphics will eventually fail within a couple of years.
I have the very same suspicion. If you actually use your computer like it is meant to be used (professionally), then it will most probably have a greatly reduced lifespan.
The MacBook Pro 15-17 unibody design from 2008-12 is very much the same inside across all generations inside and out, with the CPU and GPU close together on a narrow stretch of the logic board between twin fans and the 'palm tree' style heatsink, originally designed for the thermal dissipation of an intel core2duo CPU and nvidia 9 series GPU. Both chips attached to the heatsink by the usual over application of thermal compound.
2010 - arrandale core i5/i7 plus nvidia 3 series GPU, more heat to dissipate and more failures.
2011 - Our sandy bridge core i7/AMD models, the hottest heat combination by far of all inside a 15/17 inch MacBook Pro. The CPU is 45w and is far larger than the older chips. AMD have not disclosed its power ratings but the AMD 'northern islands' architecture these models have do run hot. 2011 is the same year that the 5 year exemption from 2006 expired for using lead free solder on CPU/GPU. The OTT thermal compound makes them run hotter doesn't help either taking heat away for a system designed for a much smaller and cooler pair of chips 3-4 years previously.
2012 - 17 discontinued, 15 has the ivy bridge i7 CPU which is in essence a shrunken version of the Sandy Bridge and runs far cooler plus the Nvidia 6 series GPU. Nvidia's new Kepler architecture, renowned for good performance with far lower power and heat. Less failures as a consequence, plus improvements in lead free soldering solutions.
In my opinion 2011 I'd describe as a perfect storm of weak points in the MacBook Pro thermal design, rectified a year later by lowering the power and the heat which are causing many of these units to fail is no coincidence. Lead free solder banned I would suggest is primary factor but I feel it's the sum of all the parts which have made this thread 4,000 long.
I don't think I'm wrong and firmly believe that those in Cupertino looking at the failure statistics do either!
) Piuttosto alla fine nessuno mi ha detto come si comporta la temperatura della cpu sui propri mac. Se è normale che mentre si apre una pagina web sale a 55 per poi riscendere dopo 2 secondi a 42 e così via. Mi è rimasto solo questo dubbio...
