Hi all! I have a problem with my Macbook air 2012. OS 10.9.5.
This morning my sound were not working so i rebooted my machine. And here the problems start. My macbook now goes into sleep mode after 5 Seconds! And when it does so, i have to unplug/plug magsafe to get it back on. Then another 5 seconds before it shuts down again. I have tried SMC and PRAM resets. I am not able to do a erase+reinstall because the Internett is lost every 5 seconds due to the black screen. However when i pressed OPTION+ON button to get into the reboot menu the screen didnt shut down. Until I clicked on Recovery, then it started again. So, has anyone had the same problem? Any solutions? Is there a connection to the no-working sound? Help is extremely appriciated!
Edit: New info: I can still charge my phone while the screen goes black, if thats helpful for you guys.
