Hi Everyone, I recently replaced a battery and a keyboard in a MacBook 2015 Pro and having issues with it randomly going to 100c and max fans as well. Mainly at bootup. Ran Apple Hardware Test and reported no issues. Nothing running that could cause it to heat up that much. Even going into the Apple Hardware Test it would rev up even before running the tests. There wasn’t this issue before replacing the parts that I’m aware of. Any ideas on what could be the issue? Attached TG Pro images:
Thanks heaps Leigh
I don’t see the fan in your capture, that’s important too! But we need to see all of this during the time things are struggling. For now I think we have a good enough clue on what’s happening. We can see the high water marks (the lines) which tells me the system has encountered time points when the processing load was quite heavy! I think your issue is likely a very full drive and/or running too many tasks concurrently. So lets get a better idea on whats happening under the covers! Look at your drive size and how much is free (unused) you want to have between 1/4 and 1/3 unused. If you don’t do a good clean up getting rid of old stuff or back it up. Next, the next time things get rough, open up Activity Monitor its in your Application/Utilities folder click on the CPU button and % CPU column so the most used is on the top, see what processes (apps) are running hard. Compare it to when things are normal thats what you need to drill down on what these processes are doing.
