macbook issue help!!!

[Clearviper]

so i recently got a 15inch macbook pro 2015 and i like it alot however its done this 3 times today

ill beusing it and it will randomly shut off completey and ill power it back on and then it shuts off again and on the 3rd try i turned it back on and i checked fan control app for the temp and it had reached over 90c degrees just from starting it up and it will randomly spike from 60-70 to -87-94c

so im wondering if its shutting off cause it reaches the max temp, 

i dont really know how to find out the issue or the main cause

Could be the ventilation is clogged. Look up a teardown for your model to show you how to open it up, then you can give it a bit of air duster action.

 

If that doesn't work, at 9 years old, it's possible that the thermal paste has degraded too far. Again, a teardown vid should show you how to repaste the CPU.

so in theroy there isnt anything wrong and its probably just a cooling issue

Is this your "pretty much brand new" one you got secondhand?

 

Who knows what kind of life it had before you got it. Check to see if the fans are clogged up with dust. It could've been sitting closed on a table connected to a monitor, mouse, and keyboard, never cycling the battery because it's always plugged in. (Cooling was never that great on the aluminum Intel Macbooks anyway; Apple prioritized low noise over cooling performance.)

 

The battery could be bad just from age, regardless of the number of cycles it has on it.

I'm not sure if I'd be confident enough to say probably. But cooling is definitely where I would start diagnostics.

you were completey right bro, i did a lot of testing with in the last few hours and it only crashes while doing really intesive stuff off the charger if its connected it does not turn off at all. it took quiet a few hours of

serching through logs and trying trial and error stuff, and at one point it crashed and wouldnt charge at all so i booted it up got it to crash and what do you know it started charging again, battery is half toast it lasts awhile but crashes alot

i ended up messaging him on facebook and told him my issue, he said he had 2 more that had actual ogrinally batterys in them so i went and returned the unit to him and he gave me one that actually had 1tb ssd in it for the same price, he had offered to to let me keep the other macbook and get 150$ back but i just wanted something that worked right out of the box, but so far so good on the different one, no shutting off or overheating.
