Got an iMAC where the first LED Blinks on button press but not turning on.
Its not Q8450 and i have steady 12V
I'm not getting pm_slp_s4_l and not pulsing either.
is the criteria for s4 en same as macbook?
that did the trick, i drill it down to SSD issue. Problem is i tried several SSD(apple ssd), known good working and tested with another macbook runs fine! but some of them were not detected at all, getting Folder logo on boot, but found 1 that boots and shut down properly now.
Macbook air 2017 initially came in with no boot, troubleshoot and found that SSD was dead. had it replaced and when running diagnostic and other stuff found it was laggy when on battery. found out Battery connector was broken. now also notice that the macbook will not/takes a long time to shut...
sorry for ranting but WTF??? board came from a customer who previously passed to a shop who says can't be fix and needed board replacement.
she needed data but sabotaging the board for business? i'll make sure this shop is properly backlisted and known to all local shops and customers to stay...
no other component that i can find that are missing related to SSD.
when you say Classic SSD failure, the NAND itself fail?
i see alot videos with same symptoms but they do a CPU reball instead and SSD is back.
