Will not power on

Not sure if your problem is the same as mine, but I am having the same issue as you are. After taking it apart the only thing I noticed was the bus ribbon cable that runs from the PCB board at the top of the keyboard and mounts around the power button and connects to the main board had the contacts coming off so they were not connecting properly. I have been unable to locate that specific ribbon cable so far other than from Ali express which makes me nervous. However most of the things I’ve read that says if the computer doesn’t power on to check this cable. Good luck and I hope you find a solution.
