MBPr random shutdowns after display/mobo replacement
I don't expect to receive help here for this issue. I'd just like to share what extreme problems I have with my 15" MBPr Late 2013 bought in early 2014. It's a 2.6 Core I7 with 16GB RAM and the 1TB SSD, to be precise.
From the start I've had random wake-from-sleep-issues that I couldn't track down. I learned to live with it, blaming it on carrying over older installations from Mac to Mac.
Around February, my display started to dissolve from the edges. So I asked my dealer what I should do. He told me to hand in the machine to our local Mac repair service (Apple authorized). Service had a cost free replacement of the display and the mainboard for me (some connection was dead and Apple replaced it). They showed me that the system was running fine at their offices for a couple of hours.
Coming home, I started to use the computer as usually – and it would shut down completeley randomly; during startup, during light usage. Rather when being on WiFi and battery than while being connected to Ethernet networking and on power. There is no warning whatsoever.
Since I still suspected, that the problem may partly be connected to my vintage base installation, I decided to install Yosemite on an external drive, boot from that, and wipe out the MBPr SSD for good. I did a zeroing of the entire SSD and started a clean install of Yosemite on the MBPr. Up to the first reboot from the internal SSD everything looked fine. But the initial boot wouldn't work. The fans came on and after about ten minutes the machine turned itself of. I turned it on again and it would show the same behavior two times and finally boot to the installation wizard.
Then I created an admin account, opened the updates panel – and the machine turned off again. This is what happens every single time now – on a fresh, empty machine.
I am writing this on this very machine while being safe booted. At the moment, this is the only way to have the MBPr usable. On monday, I'll take the machine back to service.
