    So I just got a brand new macbook pro non-retina for school, because my family didn't want me to wait. I got it just a few hours back, and it has been great except, that if I am using the computer while it is charging the charger gets really warm and the left side near the charger gets a bit warm. However, if the MacBook is off and plugged in there is no heat at all. Is this normal or is this something to do with the computer or charger? Thanks for any help.

    It is quite normal for your charger to get very hot while charging your Mac. It is also normal for your Mac to get hot while running, especially under heavy workloads.

    The Mac barely does anything, I don't even have office I currently use the web app that is free. Also, the battery drains pretty fast I think in 30 mins its down from 100% to 85% and the battery estimated life in the indicator fluctuates from time to time.

    If it is indeed a brand new system that's only a few hours old, then let it sit while powered on over night. Spotlight indexing will consume system resources as it builds its first-time index.

    Although, I'm not certain that accounts for 15% drop in battery after 30min.

    At any rate, I would start by letting it sit over night while plugged in and turned on, just to let Spotlight have enough time to finish what it needs to do. Then, after a couple days or so, if you still notice the issue, then perhaps bring it in to an Apple store and have somebody there look at it.

    Your "time remaining" indication is an ever-changing estimate, based on the current workload of your system. It will fluctuate up and down from minute to minute as your power demands change. It is not perfectly accurate, but only an estimate.

    There are many factors that impact your battery life. See the BATTERY LIFE FROM A CHARGE section of the following link for details, including tips on how to maximize your battery life.
    The link below should answer most, if not all, of your battery/charging questions. If you haven't already done so, I highly recommend you take the time to read it.
