What could have caused it? A poor job at the factory with the heat transfer paste, getting too hot a few times, the case being flexed, maybe by lifting it one-handed from a corner, or carrying it in a shoulder bag resting against your hip while walking. This probably was a symptom of an issue and/or the cause of the LB failure. I don't think you did anything 'wrong.'ĭuring normal use we used a chill mat to keep it cool and to guard us from burns as this machine gets uncomfortably hot even when web browsing. I would like to have some advice regarding practices and necessary precautions so I can avoid other machines to have the same luck.Īs already stated, electronics can just fail. Where I live, while thunderstorms are very uncommon, power outages and surges may occur from time to time. During normal use we used a chill mat to keep it cool and to guard us from burns as this machine gets uncomfortably hot even when web browsing. After being done, we put it to sleep (again plugged) rather than shutting it down. Since then we leave the computer most of the time plugged in while using it. Components, including RAM, are factory originals.Īlmost a year ago, the battery life decreased significantly (it only held charge for about 1 hour before having to plug it back). Never been dropped, and also I've never opened it (neither let someone else) to clean it on the inside. It's used only by two people (my wife an I), we've never spilled any kind of liquid onto it.

The machine is used 99% of the time at home, so I am not normally carrying it away or traveling. Unfortunately this last one was the only that did not meet my expectations. I chose the machine based on its outer construction, portability, ease of use, speed, Mac OSX and durability. I'm also aware that manufacturing processes have natural variations and that defective items can escape from quality control regimes, so this can be that I was lucky enough to end up with a defective unit.Īlthough a powerful machine, I use it mostly to light work like web browsing, music, photo and video library storage, sync an iPhone, and some video/music editing. I know that a diagnosis can only be made by examining the faulty board, however what I'd like to do is understand if there are practices which may seem “normal” during use, but instead are a time-bomb for the machine. While I'm in the decision making process of whether having it repaired or replaced, I just want to get some advice as what could have gone wrong. Yesterday my 23-month-old MacBook Pro was diagnosed with a dead logic board.
