i don't want settings turned to never. I also tried the Caffeine app but couldn't even get it to start, and so here I am.
Thanks in advance!
Go to settings. Battery. You should see options for when you want computer to sleep, shutoff, ect. I suggest only setting it to never when you are powered via ac. You could write a little shell script to detect when the barttery percentage is below x%, and send the cutoff signal to your music program. Just a thought.
