Since I got the MBP back roughly 3 weeks ago, I noticed that the battery life has diminished. And significantly that is. I can use the machine for a maximum of two hours now, whereas it can stay almost 3.5 to 4 hours before. I wonder if the logic board replacement has got anything to do with it (although I highly doubt). For all I know, this could have been going on for a while but I was just unaware of. It’s been more than a year anyway.
Anyhow, before I check with Apple Care, I decided to diagnose it myself first (not an expert, so let’s just check the stats). This way, I can avoid excuses technicians always make when dealing with customers (i.e. like try to reset PRAM first, etc).

And so it happened to me… On a Saturday morning, I am the latest victim of the Macbook Pro Early 2008 bug. Apparently, according to Apple, it is a problem with NVIDIA GeForce 8600M GT graphics processor. In my case, it is more than a distorted video. Upon bootup, it shows these distorted lines at first, tries to load the OS, then stops with Apple’s own version of BSD (Black Screen of Death i call it) [see screenshots below]. Logic board fail.
The Apple Support website has THIS explanation:
In July 2008, NVIDIA publicly acknowledged a higher than normal failure rate for some of their graphics processors due to a packaging defect. At that same time, NVIDIA assured Apple that Mac computers with these graphics processors were not affected. However, after an Apple-led investigation, Apple has determined that some MacBook Pro computers with the NVIDIA GeForce 8600M GT graphics processor may be affected. If the NVIDIA graphics processor in your MacBook Pro has failed, or fails within three years of the original date of purchase, a repair will be done free of charge, even if your MacBook Pro is out of warranty.
Apple is issuing refunds to customers who may have paid for repairs related to this issue. Please contact Apple for details on the refund process.
