Chosen Solution
I have a mid 2012 retina 15 MacBook Pro. I have a program that I use to test the computer that will let me know the FPS and the GPU heat. It seems if the computer is unplugged from a power source and goes past 80 C it will go black and a few seconds later the fans will stop spinning (shutting down). When I hit the power button it acts as if it is dead and shows a “plug device in” sign. Once I plug the computer in it will fireback up within 10 seconds and continue where it left off on the program. However if I run the same test for 20+ minutes with the power adapter connected it never shuts down. Not really sure that this is normal and would like you know the community’s thought on this issue I have experiencing. Update (09/23/2017) Here are the results from coconutbattery. I checked the battery but it seems to be “normal”. As for my current energy saver settings I have the battery power set at 2 minutes for display sleep and 10 minutes for computer sleep. Even if the display was to go to sleep I do not think I would be seeing a sign showing “plug in battery”. Thanks again guys, let me know!
You seem to have the same issue as me: a bad battery (I fix those but am too lazy to repair mine since it is plugged in all day anyway). Download and install “coconut battery” and report here the results. Also, if you click on the battery (when the charging cable is disconnected), do you get the message “replace now?” Finally, at what OS version are you now?
Go to settings –> Energy Saver. See what your settings are for “Computer Sleep” and “Display Sleep”. There are separate settings for when the MacBook Pro is on Battery vs Plugged In.
This is my coconutbattery results. Thanks!
