Mac shuts down randomly
Hi,
I have the problem, that my Mac is randomly shutting down without knowing what it causes.
First of all I have a MacBook Pro Retina 15" Late 2013. Processor 2GHz intel Core i7, 8 GB RAM, Graphics: Intel iris Pro and macOS Sierra 10.12.3. Currently there are two portions running on the computer. The second one uses Bootcamp with Win 10
This Problem appeared first since I erased my MacOS partition and reinstalled macOS (I did not erase the whole disk only the first partition). Once it happens the screen turns black (the backlight stays on) & the ventilators start to get really noisy for 5-10 seconds until the Power goes off. Once I restart the computer sometimes there is a message that the computer unexpectedly shut down, sometimes not. Furthermore the message does not look like a typical Kernel Panic message more like if someone cut off the power.
What I could figure out so far:
- If the power adapter is plugged in it normally doesn't happen, unless it just happened (while it was unplugged) if I plug it in now it might happen again even if its now plugged in.
- Disabling the Wifi reduces the probability of shutting down randomly
- Most of the times it shuts down while using a Browser (but not always!)
- While playing for example CSGO (heavy using) it never has shut down
- erasing the partition again didnt help (no extra programs where installed after reset but it still happened)
- Using Windows on the BootCamp partition works perfectly fine
- the Hardware Diagnostics did not find any error
- reseting the SMC didn't help
- it normally shuts around 90 % of battery
- sometimes if it shuts down once I restart it it shuts down again within one minute after login
I hope you can help me, I am really frustrated right now because you normaly don't expect something like that from such a device after 3 Years. Does anyone know if the Reseting without flushing the BootCamp partition can cause problems? I didnt want to wipe the whole disk so far because currently I can't reinstall Bootcamp and its sometimes the only way to use my Mac while I don't have power without being interrupted the whole time.
Oh and as the device ist 3 Years old I guess I don't have any warranty anymore.
If you guys have any other Idea what else could cause this problem or more questions I would be glad to hear. Btw. I know a lot of technical /computer science stuff so if you need me to do try anything just tell me
