2018年7月发布,15英寸 MacBook Pro,型号 A1990,拥有True Tone技术的LED背光15.4英寸显示器,最高6核心的酷睿 i7 处理器。

Why won't my MacBook Pro turn on?

Computer was on and working fine. I closed it to move to another room and it would not wake up from sleep when I opened it. No lights, no keyboard lights, no fan, no noises. Tried hard shutdown by holding power key down. Left it closed overnight and it still won't boot up. Plugged it back into power and still no response. Tried resetting SMC, but of course that does nothing. Any suggestions?

What is your charger? An original Apple unit or something else and are you using the original USB-C cable.

Original charger and usb-c. The battery was at about 90% when it wouldn't wake up.

This is not sounding good ;-{

The power logic on the logic board has failed. You’ll need to visit Apple to see if they will cover it under warranty. If not you’ll need a new logic board.
