1 Not Turning On after install of Big Sur
Hello, I have recently updated my MacBook to big sur and have not been able to turn it on since.
I have reason to believe it is a problem with the USB port not charging it or maybe the logic board.

Does the backlight turn on or do you hear a startup chime when you press the power button? If you press the power button while holding the option key does it show Macintosh HD?
