My 2007 MacBook Pro had insomnia. It would wake up randomly and refuse to go to sleep. What killed it was it woke up in a plane's overhead bin causing it die from overheating in my laptop bag. My 2012 MacBook Pro would just refuse to wake up sometimes. My 2016 MacBook Pro is sometimes slow to wake from sleep, but no major issues yet. My 2007 Mac Pro would cause a kernel panic when putting it sleep.
