Hey Everyone, This May, I will be travelling to Nepal. During my time there, I am going on a trip to the base camp at Mount Everest. It's a 12 day trek, and days 2 - 10 are spent above 10 000 feet. Also, the maximum altitude that we will be at is 17 598 feet. My plan from the beginning was to turn it off completely so that the hard drive won't be spinning, due to the problems caused by high altitude. It will be stored in its sleeve (possibly inside a larger soft case as well), and will remain inside my backpack the whole time. I did a live chat with Apple Support, and the guy that I spoke to mentioned the hard drive problems, LCD issues with high altitude, as well as low temperature issues. Any idea if these will be major concerns, if my laptop is shutdown for the entire trek and is stored in my backpack the whole time? It's not like I'm going to be trying to run it at base camp, where temperatures can be in the negatives during the day. Plus, body heat should (theoretically) transfer through to the laptop. I appreciated any help. Leaving it at home isn't an option (as people on Trip Advisor so rudely suggested in other ways regarding other electronics questions), since part of my trip involves school, so I need it. Thanks in advance!
