Macbook air is dead after High sierra update
After I updated my Macbook Air 13" early 2015 to High Sierra, everything seemed to work fine. But after the Macbook went to sleep, it never came back. It was dead. Only charging worked. After the usual debugging with Apple customer care, it didn't come back. I submitted it to the Service center and they fixed it by replacing RAM IC. Again it worked fine. Once I got it back to home and using it for a few hours, it went to sleep since it was idle for some time. It is dead again.
Has anyone faced this issue here? Is there any way to fix this issue permaenently? Is rolling back to Sierra the only solution? At this point, I am not even sure if that will be a permanent solution.
MacBook Air (13-inch, Early 2015), Mac OS X (10.7.5)
