Random Shutdown on Macbook Pro (15" mid 2014)
i have a Macbook Pro (Retina, 15', Mitte 2014) with El Capitan installed (10.11.6 (15G1004)).
It keeps randomly shutting down. This happens like this:
1. Screen turns black (does not turn off, logo-light is still on)
2. Fans accelerate,
3. After 5-10 secods, it turns off (screen & apple-logo turns off)
4. i can boot normally. no crash report.
I was not yet able to reproduce the problem. ive tried a lot:
- happens with or without power cord plugged in
- resetting the smc does not change anything
- reinstalling OSX does not change anything
- it feels like it happens mostly when having high CPU Usage, but running a benchmark (cinebench) to put pressure on the CPU does not automatically shut it down
- also happens with no CPU Usage at all (but fewer times)
What diagnostics can i provide to give you more detail?
What monitor tools are available to get more information about what happens?
Anybody encountered this... ever?
I'd appreciate your help!
MacBook Pro with Retina display, OS X El Capitan (10.11.6)
