Macbook Air "Core i5" 1.6 13" (Early 2015)
No water damage and never been dropped and sadly out of warranty and without Apple Care.
It started to crash intermittently and then started to reboot. Sometimes it would reboot and work for a while but then it started rebooting every few minutes.
I reset the VRAM & SMC and now I am stuck with a black screen and infinite boot chime.
I get one clean boot chime and then infinite distorted chimes every 2-3 seconds .. this isn't the standard 3 or 9 chimes which suggests Motherboard or RAM .. it is infinite! It doesn't stop until I hold in the Power Button.
So I popped the MBA open, knowing that the RAM couldn't be easily addressed, but considered pulling the battery for a period of time, re-seating the SSD etc etc. Nothing seemed to change.
However when I remove the video connector cable (the slightly angled one in top left corner with black tab) the infinite chime goes away and I get a standard single one chime startup. Obviously I have a black screen at this point and cannot see if the system is starting correctly.
So next step, pressing Shift Key does not put it in Safe Mode - it just hangs on Apple Logo with progress bar, however holding Command + V loads Verbose Mode and then all starts correctly, unfortunately without wifi at this point.
System Information shows the correct RAM Slots, Sizes & Status on both is OK
But rebooting causes the Infinite Chime to return.
So everything works fine in Verbose Mode, but can't Enter Regular Mode, Safe Boot, Diagnostics or Recovery Mode. How would one perform a fresh install from Verbose Mode when Wi-Fi is disabled?
Any ideas ?
