I took my Macbook in because it was hard to start. I would have to try and boot it several times.?

Question

I took it into the Apple Store and left it for servicing. I got it back and works fine, but the paperwork says they just ran a dynastic and could not find anything wrong. Is it possible they did fix something, but for some reason do not want to say? It use to heat up quite hot, but now is just gets warm (The under side). Any thoughts?

Answer 1

Probably they made some minor adjustment or something.

For example System Preferences > Energy Saver > Processor Performance > change to: Reduced. Would cause it to run cooler.
