MacBook Air 11" keeps shutting down and does not reboot
My Macbook air 11" Mid 2012 keeps shutting down and then when I try to reboot it does not come back, the power button does not respond at all.
After a couple of hours it sometime boots and takes me to the login but shuts down shortly. Sometimes it does not just want to boot at all.
The device is charged to 95% and have tried the same with power connection on as well.
The one time I was able to fully boot it in the last 2 days, I ran a full apple hardware diagnostics for over an hour and it reported no error codes or failures.
