MacBook air won't start unless I hold the power button for at least 5s
I have a MacBook Air 2013, and now it won't start up correctly, I have to push and hold the power button for at least 5 seconds, if I just push quickly it starts, it then goes to standby mode, then it shuts down completely.
Found a component that wasn't working so now at least it won't shutdown, but still a bit slowish and the power button isn't working to well, I installed a new OS onto the system but nothing changed, tried to change the power and other component but nothing.
Any clues are most welcome thanks a lot!
Well, I have two MacBook Air's (both are 2013 models), I used one as the parts to fix the other. I switched, the batteries, the I/O board, and yesterday even the screen.
I also tried reinstalling the system from scratch nothing! And I even tried the Apple hardware test, and I got "No issue found" reference code ADP000
Yesterday I changed the entire display and uppercase assemblies, and nothing!
When I gave it to a friend a month ago he found a certain chip "exploded" and changed it but since then nothing changed.
Thank you so much again :)
Is dit een goede vraag?
