Wow, I thought I was the only one. Bought mine in November 2016 and had three logic board failures of varying degrees of severity.
This is the first time I have encountered somebody with this same issue.
Did you order a unit with an English keyboard from Apple Japan? Mine is a 13" delivered on 2016/11/18 with a UK (英語-英国) keyboard. I wonder if this can be narrowed down further?
Full specs are –
• 3.3GHzデュアルコアIntel Core i7プãƒã‚»ãƒƒã‚µï¼ˆTurbo Boost使用時最大3.6GHz)
• 16GB 2,133MHzメモリ
• 512GB PCIeベースSSD
When my keyboard was replaced they swapped it out for a US keyboard (UK keyboard would have been a long wait) and the logic board problem reoccurred.
The first time it occurred was random – I was using Line (fully charged, closed, connected to a display), so nothing too intensive, and the screen suddenly went to black as if powered off. The unit randomly would switch on about a week later for a few minutes, which was not enough time to salvage anything. I could get it to switch on one last time about a month later before sending it in for repair. Behaviour was as if the unit's battery was depleted.
