My mid-2012 Macbook Pro has been shutting down several times in the past 2-3 days, with the last two times happening now and a couple of minutes ago. Originally I thought that the motherboard could be overheating because often a general area next to the fan is very hot (sometimes burning hot), so I cleaned the fan and motherboard using compressed air
the green square is in general where the excessive heat is coming from
Any help with this is greatly appreciated, because I don't know what is going on (and I fix these), because this is my school/everything else computer, and I need to be able to type on it in school.
Yes, 1. SIP is enabled 2. I recently reinstalled macOS Sierra through the recovery partition 3. There is no hard drive in the hard drive slot because recently (starting about a week ago) the computer won't read any hdds that I connevt, but the ribbon connector works 4. The hdd is in the superdrive slot
Info about the computer: mid-2012 Macbook Pro, 1tb 2012 5400rpm wd blue hdd, 16gb ram, non-apple greenbox battery, 13 inch, Intel graphics card and processor (i5 I think), has had no history of doing this (as far as I know)
It turns out that while overheating was probably a problem, and was probably going to destroy my computer, It still shuts down when everything is was cooler. I was running on battery power with my hdd connected externally. Does this suggest that there is a battery problem or a motherboard problem?
