I’m still under warranty, and Apple has ‘repaired’ it twice for this same exact issue. Apple Genius Bar opened it up, disconnected the battery and reconnected it.Attempted both SMC & NVRAM Reset by both myself and apple.If I connect my phone to it, it’ll charge/stop charging when I hold the power button down and turn it on/off but nothing otherwise. I DO hear the chime when I connect it to power.Caps lock button does not light up when pressed.Both times it was not connected to any external accessories, although on most days I do use the Vava VA-UC006 USB-C Hub for both an external display and charging. It was working a few hours ago, I shut it down, then less than an hour later went to turn it on and it did not turn on. My issue is that the laptop will not turn on, the screen stays black, I don’t even see the Apple logo.
