Sorry, SMDFlea...you are right. The MacBook Air A1466 SN is: FVHYHWZAJ1WK.You can also read in the back cover EMC3178. The MoBo is 820-00165-A.
It must be the latest batch, because it has Big Sur installed without tricks. It has 8Gb RAM, and only 120Gb SSD (I'm going to change it, amongst other things, like the startup delay problem...annoying!).

EDIT: This happens even without internal SSD. Even when you reset NVRAM; the time between chimes is veeeery looong. The curious thing is that, once started, the machine works like a charm (well...with Big Sur...I don't like it, but it works normally). I was thinking about the SMC reset signal, which can be "delayed" by any reason. But all signals in the scope appears well, compared to an older, working normally board (older, of course).

Serial number ? Read the rules.

Hello everybody: I have a problem in the bench with an A1466. It takes a lot of time since you push the PWR until the chime sounds. After that, the machine runs perfectly. But it takes 20...30 secs to gimme the chime sound. I thought maybe it will be a problem in the BIOS. This machine is an A1466 EMC3178 (it has Big Sur, so maybe the firmware was updated in the process of Big Sur installation, because the original EMC was EMC2678). I'll go to update here the bin file which is (suposedly) giving me this error, so I beg your help. TIA for your always invaluable help.

I have a a1989 that I got from marketplace but they guy who sold it to me ghosted me and I can't get past the activation lock asking for his login any help? I'm not are well versed as all of you with computers also so sorry if I sound confused

Those models have T2 security, so it's not as easy to remove activation lock. There are numerous other threads on this excellent forum that discuss T2 unlocking. Best find which version of iBridge you have installed. I'd make another thread with your issue too.
