They don't conflict. Spotlight is a pig on any first run on a newly accessed filesystem. On the other hand, Sophos will double the load caused by controlling all these filesystem accesses. I suggest you to let Spotlight terminate its heavy initial run alone by temporarily turning off the On-Access control of Sophos: I also suggest you to turn off the scan ...
Apple makes 3 different chargers for their MacBooks that you need to be concerned about: 45-Watt -- For MacBook Airs. 60-Watt -- For 13" MacBook Pros. 85-Watt -- For 15" and 17" MacBook Pros. You can use a higher-wattage charger than you MacBook requires, but not a lower-wattage one. Yours was an 85-watt charger. If your friend's charger was a 60-watt, ...
If you can at least start the Mac up and make the battery lights flash, it's lint. Here's how you clean lint from a port: Get a toothpick. Stick it in the port. Carefully rub the inside of the port. Pull out the toothpick. Repeat.
Yes, undoubtedly. I can attest that Linux installed as a dual boot partition has similar battery life to Mac. Perhaps slightly shorter due to the lesser optimisation for the hardware. In a virtual machine, despite lots of clever optimisations and CPU hardware virtualisation features, there are inevitably two whole OSes with two kernels and two display ...
yes, dual boot maybe a better way, but you will lose all pros of Macbook. There's another way of using Ubuntu, which is Docker. I bet you've heard of it, but you may not know is latest Docker beta uses a native virtualisation mechanism, and it doesn't need virtualbox any more. I hope this could make you feel comfortable
You could try, charging and uncharging it a few times, it might help. But I wouldn't really rely on that. I bought a replacement battery for my iPhone 5 via iFixit and I am really happy with it - it shouldn't be much more than 1/4 of the price you named. So make sure you don't get an extra cheap one of eBay, those won't make you happy for long.
