OK – this might not be one of my ordinary subjects but this was soooo annoying. Sometimes when I closed the lid of my MacBook Pro there were something still running. This caused the battery to drain in about 20 minutes and the computer to go very, very hot. For the first time ever I actually burned myself on a computer.
I have checked around the net for a solution, and even went into a MacStore but as the error comes and goes there’s not much security in the tips.
As suspected one process doesn’t have time to close down and just keeps running. But which one?
In my case it was something called Safe Sleep (that prevents unsaved data from being lost if the power goes out). This is disabled by the following commands in a Terminal window:
sudo pmset -a hibernatemode 0
sudo nvram "use-nvramrc?"=false
Thank you MacFixer for that solution – works perfect
