Macbook Air Shutting off itself

[christinalevinee]

I have a 2014 Macbook Air 13". Early 2014.

4GB, 128GB SSD.

The battery was charged full, I set it to download/Install High Sierra and I went to bed. It was still downloading. Computer was NOT plugged in, running on battery alone.

I woke up and the computer was off. I thought maybe it had installed and turned off or inactivity or whatever. I turned it on. It came on and after a few moments, just shut off itself.

Connected the charged and the light kept changing between green and orange. And ever since then, the laptop will not come on and stay on.

I tried the Shift+Mac key three button thing. No difference.
I got into recovery, it still shut off.

When your Mac experiences a random shut down, the best thing to do is reboot it and immediately restart it again. This two-step process is necessary because some programs don’t always shut down correctly the first time around. To begin the second reboot, select Restart from the Apple menu.

Unfortunately, just rebooting your Mac might not solve the problem. If this is the case, Apple recommends resetting the SMC, which is a subsystem of Intel processor-based Macintosh computers. It is similar in function to the older System Manager Unit (SMU) or Power Management Unit (PMU) of non-Intel Macintosh computers. The SMC controls your computer’s thermal and power management, battery charging, video mode switching, sleep and wake, hibernation, and LED indicators.
