Chosen Solution
Hey there! My system has been shutting down consistently at around 70%-80%. To add to that, once I plug in the MagSafe in for a little bit, and it lights up, I can unplug it and the system will continue working until the battery is gone. I find that certain applications like games and such turn it off, but document applications don’t.
I’ve followed alongside lots of examples: Installed CoconutBattery, made sure the design capacity is well above 70%Resetted SMC, let the computer sit from 100% to 0% multiple times already, and it doesn’t shut down in this case when I run some scripts to drain the batteryRan Apple Hardware Diagnostics with the extended test and no errors came back I was wondering if anybody has any solutions to this?
Unfortunately those look as first signs of a graphic card failure. If you use a benchmarking App such as Valley (https://benchmark.unigine.com/valley) and Mac shuts down at every lauch you have your confirmation of it. That’s probably happening right now when you use an App calling for discrete card use.
