I opened the case and tried to see in the dark if I could see a mini lightning when bending (because of a bad ground somewhere). Let's hope the problem's not mobo related. This could be motherboard or chip related (de-soldered solderings here or there), or case related. So suddenly the problem wasn't random anymore. I discovered that it would crash if I bend it : Power on, one hand on each side applying a light bend in the two directions made my MBPR crash. So I bought a 13 inchs retina as replacement and continued to diagnose my 15 inchs in parallel. An expensive operation, since the warranty was expired by 2-3 months. I took it to my local Apple provider and I was told I would have to change the motherboard. I tried all the solutions found here and there including replacing the thermal paste, smc or pram reset -> no luck. Sometimes after crashing, hard shutdown and restart, it wouldn't display or even power on the backlight, for one hour or one day and suddenly it would display again !!
It took me ages to discover what exactly did my MBPR crash, as it was crashing "randomly" for me. I was disappointed because of the evolving symptom (crashes more and more frequent and sometimes no display at power on) Crash usually with a message of "read error" or some display related crash dumps, often linked to the switching of graphic card (integrateddedicated).įor a long times a suspected some burnt chip (because of using 1-3 external screen all the day) and seeing istatmenu with crazy temperatures of 90-105☌.
I hope you'll enjoy.Īs many of retina mid-2012 owners (and perhaps other versions) I encountered the symptom of my machine crashing more and more frequently (from once per week to more times per day).
